CVE-2025-34434: AVideo < 20.1 ImageGallery Plugin Unauthenticated File Upload and Deletion

CriticalCVSS 9.3 · v4.0—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 37/100)

  • 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: 0.46% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • No fixed version is recorded, but the references include a patch (commit or PR) link.

Low priority for now. See the fix and affected versions sections below.

Primary sources: NVD · CVE.org · FIRST EPSS

AVideo versions prior to 20.1 with the ImageGallery plugin enabled is vulnerable to unauthenticated file upload and deletion. Plugin endpoints responsible for managing gallery images fail to enforce authentication checks and do not validate ownership, allowing unauthenticated attackers to upload or delete images associated with any image-based video.
