CVE-2026-33129

A flaw was found in H3, a minimal HTTP framework. A remote attacker can exploit a Timing Side-Channel vulnerability in the requireBasicAuth function. This vulnerability arises from the use of an unsafe string comparison, allowing the attacker to deduce valid passwords character-by-character by...

CVE-2026-32935

A flaw was found in phpseclib, a PHP secure communications library. When using Advanced Encryption Standard AES in Cipher Block Chaining CBC mode, a remote attacker can exploit a padding oracle timing attack. This vulnerability may allow the attacker to decrypt sensitive information by observing...
