CVE-2026-26204 1 Wazuh 1 Wazuh 2026-04-30 4.4 Medium
Wazuh is a free and open source platform used for threat prevention, detection, and response. From version 1.0.0 to before version 4.14.4, a heap-based out-of-bounds WRITE occurs in GetAlertData, resulting in writing a NULL byte exactly 1 byte before the start of the buffer allocated by strdup. Due to unsigned integer underflow and pointer arithmetic wrapping, the write lands at offset -1 from the buffer, corrupting heap metadata. A malicious actor can potentially leverage this issue through a compromised agent to cause denial of service or heap corruption by injecting a specially crafted alert into the alerts log file monitored by wazuh-logcollector. This issue has been patched in version 4.14.4.
CVE-2026-7402 2026-04-30 8.1 High
Improper Control of Interaction Frequency vulnerability in MeWare Software Development Inc. PDKS allows Flooding. This issue affects PDKS: from V16.20200313 before VMYR_3.5.2025117.
CVE-2026-6522 1 Wireshark 1 Wireshark 2026-04-30 5.5 Medium
RPKI-Router protocol dissector infinite loop in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service
CVE-2026-4775 3 Debian, Libtiff, Redhat 5 Debian Linux, Libtiff, Enterprise Linux and 2 more 2026-04-30 7.8 High
A flaw was found in the libtiff library. A remote attacker could exploit a signed integer overflow vulnerability in the putcontig8bitYCbCr44tile function by providing a specially crafted TIFF file. This flaw can lead to an out-of-bounds heap write due to incorrect memory pointer calculations, potentially causing a denial of service (application crash) or arbitrary code execution.
CVE-2026-7397 1 Nousresearch 1 Hermes-agent 2026-04-30 4.4 Medium
A security flaw has been discovered in NousResearch hermes-agent 0.8.0. This affects the function _check_sensitive_path of the file tools/file_tools.py. The manipulation results in symlink following. Attacking locally is a requirement. The exploit has been released to the public and may be used for attacks. Upgrading to version 0.9.0 is able to mitigate this issue. The patch is identified as 311dac197145e19e07df68feba2cd55d896a3cd1. Upgrading the affected component is recommended.
CVE-2026-4424 2 Libarchive, Redhat 14 Libarchive, Enterprise Linux, Enterprise Linux Eus and 11 more 2026-04-30 7.5 High
A flaw was found in libarchive. This heap out-of-bounds read vulnerability exists in the RAR archive processing logic due to improper validation of the LZSS sliding window size after transitions between compression methods. A remote attacker can exploit this by providing a specially crafted RAR archive, leading to the disclosure of sensitive heap memory information without requiring authentication or user interaction.
CVE-2026-6869 1 Wireshark 1 Wireshark 2026-04-30 5.5 Medium
WebSocket protocol dissector crash in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service
CVE-2026-4111 1 Redhat 11 Ai Inference Server, Discovery, Enterprise Linux and 8 more 2026-04-30 7.5 High
A flaw was identified in the RAR5 archive decompression logic of the libarchive library, specifically within the archive_read_data() processing path. When a specially crafted RAR5 archive is processed, the decompression routine may enter a state where internal logic prevents forward progress. This condition results in an infinite loop that continuously consumes CPU resources. Because the archive passes checksum validation and appears structurally valid, affected applications cannot detect the issue before processing. This can allow attackers to cause persistent denial-of-service conditions in services that automatically process archives.
CVE-2026-6536 1 Wireshark 1 Wireshark 2026-04-30 5.5 Medium
DLMS/COSEM protocol dissector infinite loop in Wireshark 4.6.0 to 4.6.4
CVE-2018-25298 1 Merge 1 Merge Pacs 2026-04-30 5.3 Medium
Merge PACS 7.0 contains a cross-site request forgery vulnerability that allows attackers to perform unauthorized actions by crafting malicious HTML forms targeting the merge-viewer endpoint. Attackers can submit POST requests to /servlet/actions/merge-viewer/summary with login credentials to hijack user sessions and gain unauthorized access to the PACS system.
CVE-2026-5657 1 Wireshark 1 Wireshark 2026-04-30 5.5 Medium
iLBC codec crash in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service
CVE-2026-5201 2 Gnome, Redhat 9 Gdk-pixbuf, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-04-30 7.5 High
A flaw was found in the gdk-pixbuf library. This heap-based buffer overflow vulnerability occurs in the JPEG image loader due to improper validation of color component counts when processing a specially crafted JPEG image. A remote attacker can exploit this flaw without user interaction, for example, via thumbnail generation. Successful exploitation leads to application crashes and denial of service (DoS) conditions.
CVE-2026-3288 1 Kubernetes 1 Ingress-nginx 2026-04-30 8.8 High
A security issue was discovered in ingress-nginx where the `nginx.ingress.kubernetes.io/rewrite-target` Ingress annotation can be used to inject configuration into nginx. This can lead to arbitrary code execution in the context of the ingress-nginx controller, and disclosure of Secrets accessible to the controller. (Note that in the default installation, the controller can access all Secrets cluster-wide.)
CVE-2018-25304 1 Freedownloadmanager 1 Free Download Manager 2026-04-30 8.4 High
Free Download Manager 2.0 Built 417 contains a local buffer overflow vulnerability in the URL import functionality that allows attackers to trigger a structured exception handler (SEH) chain exploitation. Attackers can craft a malicious URL file that, when imported through the File > Import > Import lists of downloads menu, causes a buffer overflow in the Location header response that overwrites the SEH chain and executes arbitrary code.
CVE-2026-5989 1 Tenda 2 F451, F451 Firmware 2026-04-30 8.8 High
A flaw has been found in Tenda F451 1.0.0.7. Affected is the function fromRouteStatic of the file /goform/RouteStatic. Executing a manipulation of the argument page can lead to stack-based buffer overflow. The attack can be launched remotely. The exploit has been published and may be used.
CVE-2025-14576 1 The Qt Company 1 Qt 2026-04-30 N/A
Insufficient validation of node IDs in Qt SVG module allows arbitrary QML/JavaScript code injection when loading malicious SVG files through the VectorImage component in Qt Quick. While QML execution is typically more restricted than native code execution, this could still lead to denial of service, information disclosure, or other impacts depending on the application's privilege level and data access.
CVE-2018-25316 1 Tenda 1 W308r 2026-04-30 9.8 Critical
Tenda W308R v2 V5.07.48 contains a cookie session weakness vulnerability that allows unauthenticated attackers to modify DNS settings by exploiting insufficient session validation. Attackers can send GET requests to the goform/AdvSetDns endpoint with a crafted admin language cookie to change DNS servers and redirect user traffic to malicious sites.
CVE-2026-7399 2026-04-30 8.1 High
Authorization bypass through User-Controlled key vulnerability in MeWare Software Development Inc. PDKS allows Privilege Abuse. This issue affects PDKS: from V16.20200313 before VMYR_3.5.2025117.
