CVE-2026-74903 1 B3log 1 Siyuan 2026-08-18 4.3 Medium
SiYuan before v3.7.4 contains an insufficient access control vulnerability in the /api/lute/spinBlockDOM endpoint, which is guarded only by CheckAuth middleware instead of CheckAdminRole like its sibling endpoint. Authenticated users with RoleEditor or RoleReader roles can invoke the endpoint to transform arbitrary DOM input, and large payloads cause endpoint starvation through per-path mutex serialization.
CVE-2026-74899 2026-08-18 9.8 Critical
openssl_encrypt versions before 1.4.0 contain a sandbox escape vulnerability in IsolatedPluginExecutor that exposes Python type objects in restricted exec() builtins. Attackers can traverse the Python class hierarchy via __class__.__mro__.__subclasses__() to access system functions and execute arbitrary OS commands.
CVE-2026-74892 2026-08-18 7.5 High
openssl_encrypt versions before 1.4.0 contain a hardcoded default secret key in the standalone telemetry server configuration that is used for API key hashing. Attackers who know this default value can predict or forge API key hashes to compromise telemetry API authentication.
CVE-2026-74887 2026-08-18 0 Low
openssl_encrypt before 1.4.0 imports Python's non-cryptographic 'random' module (Mersenne Twister PRNG) at line 15 of openssl_encrypt/modules/pqc.py. No direct calls to random.* were present in the code, so no cryptographic operation is currently affected; however, the import creates a hazard that future code could inadvertently use random.randint() instead of a cryptographically secure alternative (secrets/os.urandom), producing predictable values since the Mersenne Twister state can be recovered from approximately 624 outputs. Fixed by removing the import in 1.4.0.
CVE-2026-74882 2026-08-18 7.5 High
openssl_encrypt versions before 1.4.0 contain an insecure default configuration that trusts the entire RFC 1918 private address space in IntegrityProxyConfig trusted_proxies. Attackers on private networks can forge client certificate headers to bypass mTLS authentication when ProxyAuth validation is relaxed or modified.
CVE-2026-74877 2026-08-18 8.8 High
openssl_encrypt versions before 1.4.0 contain a missing ownership verification vulnerability in the revoke_key method that allows authenticated clients to revoke any other client's key. Attackers can revoke arbitrary keys by providing a valid ML-DSA signature, bypassing the intended ownership restriction.
CVE-2026-74872 2026-08-18 9.8 Critical
openssl_encrypt versions before 1.4.0 contain an arbitrary code execution vulnerability in the Whirlpool hash implementation that uses broad glob patterns to load .so modules without integrity verification. Attackers can place malicious .so files matching the whirlpool*py313*.so pattern in site-packages directories to achieve native code execution when the module is loaded.
CVE-2026-74867 1 B3log 1 Siyuan 2026-08-18 4.2 Medium
SiYuan versions before 3.7.4 contain a cross-site request forgery vulnerability in the session-cookie authentication branch of CheckAuth() that lacks Origin/Referer validation and sets no explicit SameSite attribute on session cookies. Attackers can craft malicious web pages that perform unauthorized actions on behalf of authenticated users by submitting requests with valid session cookies, relying on browser default SameSite policies rather than server-enforced protections.
CVE-2026-74842 1 Kira-pgr 1 Promptshopmcp 2026-08-18 6.3 Medium
A vulnerability was found in Kira-Pgr PromptShopMCP up to 5bc0cd17358e19a5415d11a531088170d7b81452. Affected is the function download_image of the file server.py of the component Image-Toolkit-MCP-Server. Performing a manipulation of the argument image_url results in server-side request forgery. The attack may be initiated remotely. The exploit has been made public and could be used. This product uses a rolling release model to deliver continuous updates. As a result, specific version information for affected or updated releases is not available. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2026-74798 1 B3log 1 Siyuan 2026-08-18 8.7 High
SiYuan kernel before v3.7.4 contains a path traversal vulnerability in the database_clean MCP tool. The tool performs only an empty-string check on the id parameter before passing it to RemoveUnusedAttributeView (kernel/model/attribute_view.go), which builds a filesystem path via filepath.Join without validating that id matches SiYuan's node-ID format. An authenticated MCP client can supply path traversal sequences in id to cause the kernel to copy an arbitrary file readable by the process into SiYuan's history directory (arbitrary file read) and then delete the original file (arbitrary file deletion). The corresponding HTTP API handler was hardened in GHSA-7hm9-v7vf-7g4w, but this MCP caller was not.
CVE-2026-74792 1 Scriban 1 Scriban 2026-08-18 7.5 High
Scriban before 7.0.0 (affected versions <= 6.6.0) contains a stack overflow vulnerability in nested array initializer parsing. Deeply nested array initializers recurse through a path (ParseArrayInitializer → ParseExpression → ParseArrayInitializer) that is not covered by the ExpressionDepthLimit counter added in the fix for GHSA-wgh7-7m3c-fx25. An attacker who can supply untrusted input to Template.Parse can trigger an uncatchable StackOverflowException that immediately terminates the process, even with the default ExpressionDepthLimit enabled.
CVE-2026-74007 2026-08-18 5.3 Medium
Unauthenticated Sensitive Data Exposure in 3D FlipBook – PDF Flipbook Viewer, Flipbook Image Gallery <= 1.16.20 versions.
CVE-2026-74004 2026-08-18 5.4 Medium
Subscriber Broken Access Control in Gravity Booster &#8211; Styles &amp; Layouts for Gravity Forms <= 6.0 versions.
CVE-2026-73997 2026-08-18 7.5 High
Unauthenticated Denial of Service Attack in Starter Templates by Kadence WP <= 2.3.3 versions.
CVE-2026-73996 2026-08-18 9.8 Critical
Unauthenticated Arbitrary File Upload in Masteriyo - LMS <= 2.3.2 versions.
CVE-2026-73994 2026-08-18 7.5 High
Unauthenticated Broken Access Control in Charitable <= 1.8.11.3 versions.
CVE-2026-73522 2026-08-18 7.5 High
COVESA Open1722 through 0.9.2 contains a stack buffer overflow vulnerability that allows unauthenticated remote attackers to write past the end of a fixed 15-slot stack array by sending a crafted UDP datagram containing more than 15 ACF-CAN messages. The avtp_to_can() function increments its write index without bounding it against the caller-supplied array size, and because the listener accepts datagrams from any sender matching a hardcoded unauthenticated stream ID transmitted in plaintext, attackers can corrupt adjacent stack memory to achieve arbitrary code execution or denial of service.
CVE-2026-73424 1 Withastro 1 Astro 2026-08-18 6.5 Medium
Astro is a web framework for content-driven websites. From 10.0.3 until 11.0.3, the Astro Vercel adapter in packages/integrations/vercel/src/serverless/entrypoint.ts accepts x_astro_path for the public /_isr function based only on the x-vercel-isr header, allowing unauthenticated GET requests to render routes protected only by Vercel edge path rules or split edge middleware. This issue is fixed in 11.0.3.
CVE-2026-73399 2026-08-18 6.5 Medium
Unauthenticated Broken Authentication in Flutterwave WooCommerce <= 3.3.0 versions.
CVE-2026-73397 2026-08-18 9.8 Critical
Unauthenticated Deserialization of untrusted data in Youzify <= 1.3.7 versions.
