CVE-2025-24017Public exploitNetwork attack vector

Unauthenticated account takeover via unescaped tag-search input

Published Jan 21, 2025 · Updated Feb 12, 2025

Cross-site scripting in YesWiki before 4.5.0 allows remote attackers to execute JavaScript through a crafted tag-search link. tools/tags/handlers/page/listpages.php inserts non-existent tag names from the tags parameter into HTML span elements without output encoding. Exploitation requires a victim to click the link; code then runs in that user's session and can expose data or alter the account and wiki content.
