CVE-2026-73698
HighCVSS 7.2Summary
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.
Risk Assessment
An attacker can escalate privileges to superuser and potentially achieve code execution. Deployments with delegated administrator accounts are at risk.
Recommendation
Upgrade FileRun to version 2026.3.0 or later. Limit the number of delegated administrator accounts and monitor changes to the df_users_permissions table.
Other vulnerabilities in FileRun
See all- CVE-2026-73699High
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.
- CVE-2026-73694High
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.
- CVE-2026-73693High
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.
- CVE-2026-14863High
FileRun up to and including version 2026.2.0 contains an OS command injection vulnerability that allows authenticated attackers to achieve remote code execution by uploading a file with a malicious filename containing shell command substitution sequences. The thumbnail generation system passes filenames wrapped in shell double-quotes directly to exec() without escapeshellarg() sanitization, allowing commands to be evaluated.
Original NVD description (English source)
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, causing the getValuesString() method in DB/DP.php to interpolate raw array values directly into an INSERT statement without parameterization. Because the underlying PDO connection uses emulated prepared statements enabling stacked queries, attackers can manipulate the df_users_permissions table to escalate a delegated administrator account to superuser privileges, and may additionally achieve code execution via unsanitized path values passed to require_once in the logs listing component.
