Denial Of Service (DoS)

markdown-it is vulnerable to Denial of Service DoS. The vulnerability is due to quadratic-time processing in the smartquotes rule when typographer: true is enabled, which allows an attacker to supply specially crafted markdown containing consecutive quotation marks and consume excessive CPU...

RUSTSEC-2026-0179 Unbounded SCRAM iteration count allows a malicious server to cause CPU-exhaustion denial of service

A malicious, compromised, or man-in-the-middle server can supply an arbitrarily large SCRAM-SHA-256 PBKDF2 iteration count during authentication. The client runs it inline with no upper bound, pinning a tokio worker thread for minutes per connection, possibly stalling the whole async runtime...
