Summary
webTareas version 2.4 and earlier allows an authenticated user to arbitrarily upload potentially dangerous files without restrictions. This is working by adding or replacing a personal profile picture. The affected endpoint is /includes/upload.php on the HTTP POST data. This allows an attacker to exploit the platform by injecting code or malware and, under certain conditions, to execute code on remote user browsers.
Exploit prediction
2.37% chance of exploitation in the next 30 days, higher than 83% of all scored CVEs (FIRST EPSS, 2026-11-08).
