The vulnerability is triggered through manipulation of the POST parameter file[] in the filemanager.php handler.

EPSS is not available, and the vulnerability is not listed in the CISA KEV catalog, suggesting no confirmed large\u2011scale exploitation yet. The attack vector is likely a remote HTTP POST request to filemanager.php with a crafted file[] parameter. Successful exploitation would grant the attacker read access to files on the server, potentially exposing sensitive data or configuration files. The vulnerability does not inherently provide code execution but could be leveraged in a broader compromise if sensitive files are read or if an attacker later injects code via other channels."}}}}, "created": "2026-04-17T20:40:08.867973+00:00", "updated": "2026-04-18T09:30:25.677396+00:00", "vendors": ["prasathmani", "prasathmani$PRODUCT$tiny_file_manager"]}
