CVSS v3.1 |
| A flaw has been found in HKUDS nanobot up to 0.2.1. The impacted element is the function ExecTool._prepare_command of the file nanobot/agent/tools/shell.py of the component Login-shell Environment Handler. Executing a manipulation can lead to information disclosure. The attack requires local access. The exploit has been published and may be used. Upgrading to version 0.3.0 is sufficient to resolve this issue. This patch is called 4525. The affected component should be upgraded. Multiple issues were reported to the project. They reacted with a high level of professionalism and kindness: "The report concerns shell startup files reintroducing environment variables when command execution defaults to a login shell. The default was changed so exec does not use a login shell unless explicitly requested". |

| In the Linux kernel, the following vulnerability has been resolved:
KVM: SVM: Bump asid_generation on CPU online to avoid ASID collision after hotplug
If a vCPU stays scheduled out (or blocked) while the last pCPU it ran
on goes through a hotplug cycle (online->offline->online), and the vCPU
then resumes execution on the same pCPU, then it is possible for it to
run with an ASID that has now been assigned to a different vCPU,
resulting in stale TLB translations being used.
svm_enable_virtualization_cpu() resets asid_generation to 1 and sets
next_asid to max_asid + 1 on every CPU online event, including hotplug
cycles. Because next_asid starts beyond the pool boundary, the first
call to new_asid() after an online event always wraps the pool,
incrementing asid_generation to 2 and assigning ASIDs starting from
min_asid.
Consider two vCPUs from different VMs, vCPU-A pinned to CPU-X holding
asid_generation=2 and ASID=N from before the hotplug event:
1. CPU-X goes offline and back online: asid_generation resets to 1,
next_asid = max_asid + 1.
2. One or more vCPUs migrate to CPU-X and call new_asid(), wrapping
the pool and consuming ASIDs starting from min_asid. Eventually
vCPU-B from a different VM is assigned asid_generation=2, ASID=N
— the same ASID that vCPU-A held before the hotplug.
3. vCPU-A enters pre_svm_run() on CPU-X: current_vmcb->cpu is
unchanged so the migration branch is skipped. Its saved
asid_generation=2 matches sd->asid_generation=2, so the generation
check silently passes and vCPU-A continues running with ASID=N —
the same ASID just freshly assigned to vCPU-B.
Both vCPUs from different VMs now run on CPU-X with the same ASID,
causing them to share NPT TLB entries and producing stale translations.
The collision manifests as a KVM internal error (Suberror: 1, emulation
failure). The NPT page fault reports a faulting GPA far outside the
VM's physical memory range — a sign of stale TLB translations being
used. KVM falls back to instruction emulation, which fails on
FPU/XSave instructions (XRSTOR, STMXCSR) that the emulator does not
implement.
Fix this by incrementing asid_generation instead of resetting it to 1
in svm_enable_virtualization_cpu(). On module load, asid_generation
starts at 0 (memset) and the increment produces 1, identical to the
old behaviour. On subsequent hotplug cycles the generation advances
beyond any value a vCPU previously observed on this CPU, so the
generation check in pre_svm_run() reliably forces new_asid() on every
vCPU after every hotplug cycle. |
| In the Linux kernel, the following vulnerability has been resolved:
sched_ext: Preserve rq tracking across local DSQ dispatch
dispatch_to_local_dsq() can run from scx_bpf_dsq_move_to_local() while
ops.dispatch() has recorded the current rq. Moving a task to a local DSQ
may switch to the source or destination rq before synchronously invoking
ops.dequeue() through the following path:
SCX_CALL_OP(dispatch, rq)
ops.dispatch()
scx_bpf_dsq_move_to_local()
scx_flush_dispatch_buf()
finish_dispatch()
dispatch_to_local_dsq()
scx_dispatch_enqueue()
local_dsq_post_enq()
call_task_dequeue()
SCX_CALL_OP_TASK(dequeue, locked_rq, ...)
The nested callback saves the recorded rq and restores it on return. If
the rq tracking does not follow the lock switch, update_locked_rq() can
trigger the following lockdep assertion while restoring an rq which is
no longer held:
WARNING: kernel/sched/sched.h:1641 at call_task_dequeue+0x160/0x170
Call Trace:

Introduce switch_rq_lock() to update the tracking state together with
each rq lock handoff. Use it in dispatch_to_local_dsq(),
move_remote_task_to_local_dsq() and the in-balance paths of
scx_dsq_move(), ensuring that scx_locked_rq() consistently refers to the
rq whose lock is actually held throughout the lock dance. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: validate ACE size against SID sub-authorities
set_ntacl_dacl() validates sid.num_subauth before copying an ACE, but
does not verify that the declared ACE size contains all sub-authorities
described by that field. An undersized ACE can therefore be copied
and later make the POSIX ACL deduplication walk inspect data beyond
the copied ACE boundary.
The existing initial bound check is also too small. It only ensures
that the ACE size field is accessible before set_ntacl_dacl() reads
sid.num_subauth farther into the input buffer.
Require enough input for the fixed SID header before accessing
num_subauth, reject ACEs smaller than that header, and skip ACEs
whose declared size cannot contain the complete SID. This makes the
validation consistent with the other ACE walk paths. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: bound DACL dedup walk to copied ACEs
set_ntacl_dacl() can stop copying ACEs before consuming the full input
DACL when size accounting overflows.
When that happens, num_aces reflects only the ACEs that were actually
copied into the output DACL, but set_posix_acl_entries_dacl() still
receives nt_num_aces and uses it to walk the existing ACE array during
dedup.
That makes the dedup walk scan past the copied ACE array and inspect
buffer tail that does not contain valid ACEs.
Split the two meanings currently carried by the NT ACE count. Pass the
number of copied NT ACEs to bound the dedup walk, and preserve the
original "input DACL had NT ACEs" state separately for the
Everyone/default ACL fallback.
This keeps the dedup walk aligned with the ACEs that are actually
present in the rebuilt DACL. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: validate num_subauth when copying ACE in set_ntacl_dacl
set_ntacl_dacl() copies each ACE from the attacker-controlled stored
security descriptor verbatim into the response DACL without checking
sid.num_subauth. The ACE bytes (including an unchecked num_subauth)
originate from an authenticated SMB2_SET_INFO(SecInfo=DACL) that is
stored raw via ksmbd_vfs_set_sd_xattr(); parse_dacl() rejects a bad ACE
with `break` rather than an error, so parse_sec_desc() still returns
success and the malformed SD reaches the xattr intact.
On a subsequent SMB2_QUERY_INFO(SecInfo=DACL) for an inode carrying a
POSIX access ACL, build_sec_desc() -> set_ntacl_dacl() ->
set_posix_acl_entries_dacl() walks the copied ACEs and reads
ntace->sid.sub_auth[ntace->sid.num_subauth - 1]
with num_subauth taken straight from the stored SD. Since sub_auth[]
is fixed at SID_MAX_SUB_AUTHORITIES (15), a crafted num_subauth (e.g.
255) drives an out-of-bounds heap read of ~1 KB with an offset fully
controlled by an authenticated client.
The sibling functions already gate this field:
parse_dacl() -- num_subauth == 0 || > SID_MAX_SUB_AUTHORITIES
parse_sid() -- num_subauth > SID_MAX_SUB_AUTHORITIES
smb_copy_sid() -- min_t(u8, num_subauth, SID_MAX_SUB_AUTHORITIES)
set_ntacl_dacl() is the lone inconsistent path that omits the check.
Add the same num_subauth validation in set_ntacl_dacl() before copying
the ACE, matching the gate already enforced by parse_dacl(). |
| A missing authentication vulnerability in dulldusk/phpfm through 1.8.0 allows an unauthenticated remote attacker to access the full file manager functionality including reading, writing, deleting, and uploading files anywhere on the server filesystem. |
| HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.11, XhtmlParser.java imposes no maximum element nesting depth, so a deeply nested text.div narrative triggers unbounded recursion between parseElementInner() and parseElement(), raising a StackOverflowError. An attacker who can submit FHIR resources containing such narratives can thus crash a parsing or validation worker thread, affecting validator services and any application that parses attacker-supplied FHIR JSON or XML. This issue is fixed in version 6.9.11. |
| Pathling is a set of tools that make it easier to use FHIR and clinical terminology within health data analytics. Prior to version 2.0.0 of Pathling Server, Pathling's `/$result` endpoint allows a caller who can obtain any valid async export job ID to supply `file` parameter values containing path traversal sequences. The handler verifies only the supplied `job` and never normalises or confines the requested `file` path to that job's `jobs/<jobId>` directory before opening it as a filesystem resource. Because async export scratch space lives under the same warehouse database root as persisted resource tables, an attacker can use their own export job to read other files from the warehouse. This is fixed in Pathling Server 2.0.0. The `$result` handler now resolves and canonicalizes the requested file path and rejects any request that escapes the job's `jobs/<jobId>` directory. As an interim mitigation, disable the async export operations (`pathling.operations.exportEnabled`, `patientExportEnabled`, `groupExportEnabled`, `bulkSubmitEnabled`) or enable authentication and restrict export capability to trusted callers. |
| Pathling is a set of tools that make it easier to use FHIR and clinical terminology within health data analytics. Prior to version 2.0.0 of Pathling Server, the `$import-pnp` operation in Pathling Server accepts a caller-supplied `exportUrl` and uses it as the remote FHIR Bulk Export endpoint without constraining it to a trusted source. When PNP credentials are configured, Pathling builds a credentialed bulk-export client targeting the caller-chosen host, downloads manifest-selected files, and then reclassifies those staged files as trusted local `file://` imports - bypassing the configured `allowableSources` allowlist that protects the ordinary `$import` operation. This is fixed in Pathling Server 2.0.0. As a workaround, disable the `$import-pnp` operation (`pathling.operations.importPnpEnabled=false`) or do not configure PNP credentials. |
| Element Call is a native Matrix video conferencing application. Versions 0.5.17 through 0.19.3 report analytics data to a PostHog server, when configured to by a `posthog` key in config.json or by the `posthogApiHost` and `posthogApiKey` URL parameters. Several fields of this data (`$initial_person_info`, `$session_entry_url`, and `$current_url`) were found to contain the full URL of the user's visited page, including the fragment. Users of a standalone Element Call ‘SPA’ instance such as https://call.element.io may therefore have reported the full URLs of certain calls, including encryption passwords, to the configured PostHog server, potentially compromising the confidentiality of the calls to actors who could access both the PostHog analytics data and the encrypted media streams. The same issue is present in Element Call's embedded package, but in practice it does not impact applications using this package (including Element Web, Element Desktop, Element X iOS, and Element X Android) because they distribute encryption keys over Matrix rather than encoding a password in the URL. The issue is patched in Element Call 0.19.4. Some workarounds are available. Users may opt out of analytics in the 'Feedback' tab of Element Call's settings and create new links for future calls. Admins who host Element Call as a standalone application may disable PostHog analytics entirely by removing the `posthog` key from their deployment's config.json file. |
| Hono is a Web application framework that provides support for any JavaScript runtime. From 3.8.0 to 4.12.33, memo() from hono/jsx retains the result of a server side render and reuses it for later renders with comparator equal props, and request scoped values read inside the component take no part in that comparison, so a response can contain HTML rendered for another user's request. Components wrapped with memo() are compared by props alone; values read implicitly during rendering, such as JSX Context through createContext() and useContext(), useRequestContext() from hono/jsx-renderer, and getContext() from hono/context-storage, do not participate, and the retained result lives as long as the wrapped component, so it outlives the request that produced it. A user may receive a response containing HTML rendered for another user when both render the same memoized component with comparator equal props on the same warm instance, which may disclose another user's account or profile data, disclose request scoped secrets embedded in HTML such as CSRF tokens, or expose role specific content to users who should not receive it. This issue is fixed in version 4.12.34. |
| An unrestricted file upload vulnerability in dulldusk/phpfm through 1.8.0 allows an unauthenticated remote attacker to execute arbitrary PHP code on the server. The application ships with an empty upload extension filter ( = array) and no authentication enabled by default (auth_pass is empty string), allowing an unauthenticated attacker to upload a PHP webshell and execute it by browsing to the uploaded path. |
| A server-side request forgery (SSRF) vulnerability in gabehf/Koito through v0.3.2 allows an authenticated user to make the server perform HTTP requests to arbitrary internal or external hosts by supplying a crafted image_url value in the PATCH /apis/web/v1/album/{id}/image endpoint. |
| An OS command injection vulnerability in alseambusher/crontab-ui through 0.4.2 allows an unauthenticated remote attacker to inject arbitrary cron job entries by sending a crafted GET request to /crontab with URL-encoded newlines in the env_vars parameter. |
| An OS command injection vulnerability in alseambusher/crontab-ui through 0.4.2 allows an unauthenticated remote attacker to execute arbitrary system commands by importing a crafted crontab database file. The POST /import endpoint accepts arbitrary .db files and overwrites the application database without validation. |
| A user enumeration vulnerability in bluewave-labs/Checkmate through 2.1.0 allows an unauthenticated remote attacker to determine whether a given email address is registered. The POST /api/v1/auth/recovery/request endpoint returns HTTP 200 for registered email addresses and a different status code for unregistered ones, enabling attackers to enumerate valid user accounts. |
| A cache poisoning vulnerability in CoreBunch/Instatic through 0.0.14 allows an unauthenticated remote attacker to poison the shared process-wide render cache by manipulating the u query parameter of the GET /_instatic/hole/<nodeId> server island endpoint. |
| A missing authentication vulnerability in frangoteam/FUXA through 1.3.3 allows an unauthenticated remote attacker to query all historical sensor data via the DAQ_QUERY Socket.IO event. When secureEnabled=true, all other sensitive Socket.IO events (DEVICE_BROWSE, HOST_INTERFACES, DEVICE_TAGS_REQUEST, etc.) call isSocketAdminAuthorized to verify the connection token, but the DAQ_QUERY handler in server/runtime/index.js lacks this check entirely. |
