CVE-2025-52995: File Browser vulnerable to command execution allowlist bypass

MediumCVSS 6.6 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 26/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.63% (FIRST EPSS); higher than 50.6% of all records.
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. Special conditions such as timing or configuration are required.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: filebrowser filebrowser 2.33.10.

Low priority for now. Upgrade to filebrowser filebrowser 2.33.10 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit files. Prior to version 2.33.10, the implementation of the allowlist is erroneous, allowing a user to execute more shell commands than they are authorized for. The concrete impact of this vulnerability depends on the commands configured, and the binaries installed on the server or in the container image. Due to the missing separation of scopes on the OS-level, this could give an attacker access to all files managed the application, including the File Browser database. This issue has been patched in version 2.33.10.
