SillyTavern: Path Traversal allows file existence oracle

Summary A path traversal vulnerability in the static file route handler allows any unauthenticated user to determine whether files exist anywhere on the server's filesystem. By sending percent-encoded ../ sequences %2E%2E%2F in requests to static file routes, an attacker can check for the existen...

Arbitrary File Read via Percent-Encoded Path Traversal in nltk.data.find() / nltk.data.load() - Incomplete Fix of Issue #3504

The security fix for path traversal PR 3522, pathsec module that was merged into NLTK 3.9.3 to address GitHub Issue 3504 is incomplete. The UNSAFENOPROTOCOLRE regex in data.py:57 checks for literal ../ but url2pathname on line 653 decodes percent-encoded sequences after the validation, not before...
