Fastfeedparser
Monthly
Unbounded recursion in FastFeedParser (Python RSS/Atom parser) allows remote attackers to crash applications via malicious HTML meta-refresh redirect chains. Affecting all versions prior to 0.5.10, attackers can trigger denial-of-service by serving infinite meta-refresh redirects when parse() fetches attacker-controlled URLs, exhausting the Python call stack with no recursion depth limit. EPSS data not available, no public exploit identified at time of analysis, but exploit development is trivial given the straightforward attack vector requiring only HTTP server control.
