NVD description

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.

    Disclosure

    VulnCheck disclosed four FileRun vulnerabilities enabling remote code execution and privilege escalation before version 2026.3.0. CVE-2026-73693 permits command substitution through uploaded filenames in the contact-sheet handler, while CVE-2026-73694 enables shell commands through the superuser FFmpeg test endpoint. CVE-2026-73698 allows delegated administrators to inject stacked SQL statements; chained with unsafe permission deserialization (CVE-2026-73699), it enables webshell deployment and code execution without superuser privileges. FileRun 2026.2.1 did not remediate the two command injections. Version 2026.3.0, released September 6, 2026, fixes all four vulnerabilities and removes shell interpretation from external-program calls.

    Post summary

    VulnCheck disclosed four critical FileRun vulnerabilities with detailed exploitation vectors, and FileRun released a patch (2026.3.0) to remediate them.
