Directory Traversal

zip-lib is vulnerable to Path Traversal. The vulnerability is due to improper caching of path validation results during archive extraction, where directory traversal checks are bypassed after the initial symlink validation, allowing attackers to extract files outside the intended target directory...

CVE-2026-47078

The CVE affects Erlang/OTP stdlib’s zip handling (lib/stdlib/src/zip.erl). zip:unzip/1,2 and zip:extract/1,2 validate entry paths with zip:check_dir_level/2, which tracks directory depth; while .. can decrement the counter and normal components increment it, a path like ../x/y may become negative...

Important: python3.14

Issue Overview: tarfile.extractall with the 'data' or 'tar' filter could be bypassed by a crafted archive where a hardlink references a symlink stored at a deeper name than the hardlink itself. The extraction fallback validated the symlink at it's archived location but recreated it at the...
