smallbitvec: Integer overflow in safe API leads to heap buffer overflow

Summary An integer overflow in the internal capacity calculation of smallbitvec can lead to an undersized heap allocation, resulting in a heap buffer overflow through safe APIs only. This allows memory corruption without requiring unsafe code from the caller. Details The issue originates from...

SharpCompress has directory traversal via directory entries in WriteToDirectory (zip slip variant)

Summary A path traversal vulnerability in IArchive.WriteToDirectory allows a malicious archive to create directories outside the intended extraction root. For TAR archives, this can be escalated to arbitrary file writes by chaining with a symlink entry, giving a full write primitive on the target...

epa4all-client has a VAU Signature bypass

Impact In SignedPublicKeysTrustValidatorImpl.isTrusted, the ECDSA signature verification at line 45 discards the boolean return value of Signature.verify. The method performs certificate chain validation, OCSP check, and signature algorithm setup, but never checks whether the signature actually...

Mistune has XSS via unescaped figclass/figwidth in Figure directive

In src/mistune/directives/image.py, the renderfigure function concatenates figclass and figwidth options directly into HTML attributes without escaping lines 152-168. This allows attribute injection and XSS even when HTMLRendererescape=True is used, because these values bypass the inline renderer...

Mistune Math Plugin has an XSS Escape Bypass

Summary The mistune math plugin renders inline math $...$ and block math $$...$$ by concatenating the raw user-supplied content directly into the HTML output without any HTML escaping. This occurs even when the parser is explicitly created with escape=True, which is supposed to guarantee that all...

view_component: System Test Entry Point Path Check Allows Sibling Directory Escape

Summary The system test entrypoint canonicalizes a user-controlled file path with File.realpath, then checks whether the resolved path starts with the temp directory path. This is not a safe containment check because sibling directories can share the same string prefix. Severity: Medium; test-rou...

view_component: Preview Route Can Dispatch Inherited Helper Methods

Summary The preview route derives an example name from the URL and calls it with publicsend. The code does not verify that the requested method is one of the preview examples explicitly defined by the preview class. As a result, inherited public methods on ViewComponent::Preview are...

Summary EmlParser.getrawbodytext recurses unconditionally for every nested message/rfc822 attachment without any depth limit. An attacker who can supply a badly crafted EML file with approximately 120 nested message/rfc822 parts triggers an unhandled RecursionError and aborts parsing of the...

LangChain vulnerable to unsafe deserialization of attacker-controlled objects through overly broad `load()` allowlists

LangChain contains older runtime code paths that deserialize run inputs, run outputs, or other application-controlled payloads using overly broad object allowlists. These paths may call load with allowedobjects="all". This does not enable arbitrary Python object deserialization, but it does allow...

free5GC's NEF crashes via logger.Fatal on PFD notification delivery failure (attacker-controlled notifyUri)

Summary free5GC's NEF terminates the entire process when a stored PFD-subscription notifyUri cannot be reached.
