CVE-2026-49490 May 31, 12:07 HIGH This Week

SQL injection in OpenCATS 0.9.1a and later allows authenticated attackers to execute arbitrary SQL queries against the backend database by abusing DataGrid filter handling on the Candidates module's Tags column. The flaw bypasses the application's column filterable restrictions, enabling data theft or modification of the recruitment platform's stored candidate records. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.

CVE-2026-49489 May 31, 12:04 HIGH POC This Week

SQL injection in OpenCATS through 0.9.7.4 allows authenticated users to extract arbitrary database contents by injecting malicious SQL into the sortDirection parameter of ajax/getDataGridPager.php. Publicly available exploit code exists (Exploit-DB 52579, Packet Storm), and the issue was disclosed via a GitHub Security Advisory coordinated with VulnCheck. The CVSS 4.0 base score of 8.4 reflects high confidentiality impact with a subsequent-system scope change, though exploitation requires a valid low-privileged account.

CVE-2026-27760 Apr 28, 13:43 CRITICAL POC PATCH Act Now

Remote code execution in OpenCATS installer allows unauthenticated attackers to inject and execute arbitrary PHP code by manipulating the AJAX endpoint's databaseConnectivity action parameter. The injected code persists in config.php and executes on every page load while the installation wizard remains incomplete. Publicly available exploit code demonstrates breakout from define() string context using quote and statement separator techniques. Patch available via GitHub commit 3002a29, though CVSS AC:H (high complexity) suggests exploitation requires specific timing or environmental conditions during installation phase.
