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...

CVE-2026-44336

PraisonAI is a multi-agent teams system. Prior to version 4.6.34, PraisonAI's MCP Model Context Protocol server praisonai mcp serve registers four file-handling tools by default — praisonai.rules.create, praisonai.rules.show, praisonai.rules.delete, and praisonai.workflow.show. Each accepts a pat...
