CVE-2026-76635
baserCMS before 5.3.0 contains a SQL injection vulnerability in BcDatabaseService.php that allows authenticated administrators to inject attacker-controlled table names and configuration values directly into SQL statements across sequence update, CSV export, and table management operations. Attackers can chain a backup restore code injection flaw, where PHP code outside class definitions in schema files executes unconditionally upon loading, to plant malicious table names and trigger error-based SQL injection that retrieves database version, schema contents, and arbitrary data from the PostgreSQL backend.
