CVE-2026-14863

FileRun before 2026.3.0 contains a PHP object injection vulnerability caused by incorrect options passed to unserialize() in the Perms::getPerms() method. An authenticated attacker with database write access can inject a serialized gadget chain into permissions table columns processed on every authenticated page load to write arbitrary files, such as PHP webshells, to web-accessible paths.

FileRun before 2026.3.0 contains a SQL injection vulnerability that allows delegated or simple administrators to execute arbitrary SQL by submitting the description parameter as an array. The getValuesString() method in DB/DP.php interpolates raw array values directly into an INSERT statement without parameterization, and the PDO connection uses emulated prepared statements enabling stacked queries. Attackers can manipulate the df_users_permissions table to escalate a delegated administrator to superuser, and may additionally achieve code execution via unsanitized path values passed to require_once in the logs listing component.

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.

FileRun before 2026.3.0 contains an OS command injection vulnerability in the PhotoProofSheet handler. An authenticated user with upload permission can execute arbitrary commands by uploading files with shell metacharacters in their names, such as backticks, semicolons, or $() sequences, then triggering the PhotoProofSheet endpoint. This is due to missing escapeshellarg() sanitization in the ImageMagick montage command construction.
