CVE-2026-73694

HighCVSS 7.2
Published: Translated: NVD NIST

Summary

FileRun before 2026.3.0 contains an OS command injection vulnerability caused by a no-op redefinition of escapeshellcmd() in CLI.php that strips shell-metacharacter escaping. Attackers can exploit this interactively via image_preview.php with a crafted args parameter (requiring superuser authentication) or persistently by storing malicious payloads in thumbnails_ffmpeg_args or thumbnails_ffmpeg_ss that execute when any user triggers video thumbnail generation.

Risk Assessment

An attacker can execute arbitrary commands as the web-server user, leading to server compromise. The persistent path does not require superuser privileges, increasing exposure.

Recommendation

Upgrade FileRun to version 2026.3.0 or later. Inspect and clean the thumbnails_ffmpeg_args and thumbnails_ffmpeg_ss configuration values.

Original NVD description (English source)

FileRun before 2026.3.0 contains an OS command injection vulnerability caused by a no-op redefinition of escapeshellcmd() in CLI.php that strips shell-metacharacter escaping, allowing attacker-controlled input to reach an exec() sink unsanitized. Attackers can exploit this through an interactive path via image_preview.php with a crafted args parameter requiring superuser authentication, or through a persistent path by storing malicious payloads in thumbnails_ffmpeg_args or thumbnails_ffmpeg_ss that execute when any user triggers video thumbnail generation.
