Technical details
FileRun redefines PHP's escapeshellcmd() function as a no-op in CLI.php, effectively disabling shell metacharacter escaping. This allows attacker-controlled input to reach exec() sinks unsanitized. The vulnerability can be exploited through two paths: (1) an interactive attack via image_preview.php with a crafted args parameter, requiring superuser authentication, or (2) a persistent attack by injecting malicious payloads into thumbnails_ffmpeg_args or thumbnails_ffmpeg_ss configuration fields, which then execute when any user triggers video thumbnail generation. The root cause is the neutralization of a critical security function that should prevent shell injection. FileRun 2026.3.0 patches this vulnerability; versions before 2026.3.0 are affected.
