Overview nltk is a Natural Language Toolkit NLTK is a Python package for natural language processing. Affected versions of this package are vulnerable to Server-side Request Forgery SSRF via the validatenetworkurl address-policy check in nltk/pathsec.py. An attacker can make a strict-mode...

GHSA-XW9Q-2MV6-9FR8 Fedify has an incomplete SSRF mitigation after GHSA-p9cg-vqcc-grcx: validatePublicUrl allows special-use IPv4 ranges

Summary Fedify previously addressed SSRF/internal network access in GHSA-p9cg-vqcc-grcx by adding public URL validation before runtime document and media fetching. However, the current IPv4 validation logic appears incomplete. The validatePublicUrl protection relies on isValidPublicIPv4Address to...
