CVE-2026-42574

The CVE-2026-42574 issue affects apko dirFS used to build/publish OCI images. A crafted APK could place a TypeSymlink tar entry whose target points outside the build root, enabling traversal to host paths via subsequent directory creation or write operations within the same or later archive. Root...

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...

CVE-2026-44340

PraisonAI is a multi-agent teams system. Prior to version 4.6.37, the safeextractall helper that all recipe pull, recipe publish, and recipe unpack flows route through validates each archive member's name for absolute paths, .. segments, and resolved-path escape — but does not validate...

CVE-2026-44340

PraisonAI prior to 4.6.37 does not validate member.linkname or reject symlink/hardlink archive members in _safe_extractall, and calls tar.extractall(dest_dir) without a data filter. A bundle could contain a symlink inside dest_dir with a linkname outside it, followed by a file path traversing the...
