CVE-2026-18968Public exploitNetwork attack vector

Reflected XSS via unescaped tag parameter

Published Aug 5, 2026 · Updated Aug 5, 2026

Reflected XSS in ttttonyhe OBlog allows remote attackers to execute script in a victim's browser through a crafted tags.php URL. In tags.php, the archive-banner h2 directly echoes the tag query value from $_GET without HTML output encoding, allowing markup to enter the response. OBlog 3ca6a45a2fcc81f6086751d8af124658720e8f8f is affected; exploitation needs no account but requires a victim to open the crafted link, and the published assessment limits impact to rendered-page integrity.
