CVE-2026-55529 PraisonAI: Origin validation bypass in MCP HTTP Stream transport allows browser-mediated unauthenticated tool execution on local MCP server

PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.58, the MCP HTTP Stream validateorigin method accepts requestorigin.startswithallowed, so the attacker-controlled localhost.evil.example HTTP origin matches the localhost allowlist. Without an API key, a malicious webpage can submit...

CVE-2026-77814

ispathtrusted in scripts/iib/api.py compares the requested path against each allowed parent directory with path.startswithparentpath, without appending a path separator. A directory whose name merely begins with an allowed path therefore satisfies the comparison, so where /data/images is allowed ...

CVE-2026-77814

Infinite Image Browsing , a Stable Diffusion WebUI extension, contains a path traversal flaw in is_path_trusted (scripts/iib/api.py). The function uses path.startswith(parent_path) without appending a path separator, so a directory whose name merely begins with an allowed path (e.g., /data/images...
