Symlink Attack

Overview tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed. Affected versions of this package are vulnerable to Symlink Attack via StaticFileHandler.validateabsolutepath in tornado/web.py, which uses os.path.abspath to validate that a...

CVE-2026-103754 Ansible-runner: ansible-runner: path traversal and symlink escape in unstream_dir() allows file write outside the target directory

A flaw was found in ansible-runner. The unstreamdir function, which receives and extracts a streamed zip archive on the worker side of the ansible-runner transmit/worker protocol, re-creates symbolic links from archive content without validating the link target and applies chmod and utime to an...
