python: Python: CPU Denial of Service in HTML parser via repeated unterminated markup declarations

A flaw was found in Python. Its incremental HTML parser can be exploited by a remote attacker. By sending specially crafted, uncontrolled data with repeated, incomplete markup declarations, the attacker can cause the system to consume excessive central processing unit CPU resources. This leads to...

CVE-2026-73628

Serendipity versions = 2.3.5 and . In include/functionsrouting.inc.php serveSearch, the sanitisation pipeline runs urldecode after HTML-encoding, so a single URL-encoded HTML payload survives striptags and htmlspecialchars and is then decoded back into live HTML in the page. A crafted search link...
