CVE-2026-1552Public exploitNetwork attack vector

Database disclosure via unfiltered searchml SQL input

Published Jan 29, 2026 · Updated Jan 29, 2026

SQL injection in SEMCMS 5.0 allows remote authenticated users to read database data through searchml in SEMCMS_Info.php. SEMCMS_Info.php incorporates the externally supplied searchml value into an SQL statement without validation or sufficient filtering. A valid SEMCMS session is required; the published UNION-based request demonstrates database reads, while broader effects depend on database privileges.
