CVE-2025-52996: File Browser's Password Protection of Links Vulnerable to Bypass

MediumCVSS 4.3 · v3.1—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 17/100)

  • 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: 0.38% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

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. In versions 2.32.0 and prior, the implementation of password protected links is error-prone, resulting in potential unprotected sharing of a file through a direct download link. This link can either be shared unknowingly by a user or discovered from various locations such as the browser history or the log of a proxy server used. At time of publication, no known patched versions are available.
