HighCVSS 7.1 · v4.0—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 28/100)

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. A low-privileged account is enough. No user action is required. 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.

Primary sources: NVD · CVE.org · FIRST EPSS

WWBN AVideo contains a path traversal vulnerability in plugin/AI/receiveAsync.json.php that allows holders of any valid AI token to write arbitrary .vtt files by injecting traversal sequences into the unsanitized response[lang] parameter. Attackers can send a type=translation request with a crafted lang value to plant attacker-controlled content in the webroot or overwrite other users' subtitle files.

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.
