CVE-2026-30994Public exploitNetwork attack vector

Credential disclosure via public session log

Published Apr 15, 2026 · Updated Apr 15, 2026

Sensitive information exposure in Slah CMS 1.5.0 and earlier allows remote attackers to read active session credentials without authentication. The session() function in config.php appends every session key and value in plaintext to the web-accessible public/assets/js/logged.js static file. Any network client can retrieve the file directly, exposing usernames, passwords, login state, and user identifiers that enable administrative account access.
