DescriptionCVE.org

AVideo through 29.0 contains an information disclosure vulnerability in plugin/Live/stats.json.php that allows unauthenticated attackers to retrieve stream keys and m3u8 URLs by accessing the endpoint without authentication. Attackers can enumerate private, unlisted, and group-restricted live streams by parsing the hidden_applications array in the JSON response to obtain sensitive streaming credentials.

AnalysisAI

Unauthenticated information disclosure in AVideo through 29.0 exposes private live-stream credentials - including stream keys and m3u8 playlist URLs - to any network-accessible attacker who queries the unprotected plugin/Live/stats.json.php endpoint. The hidden_applications array in the JSON response contains metadata for private, unlisted, and group-restricted live streams that the platform explicitly intends to conceal from unauthorized viewers. …

Vulnerability AssessmentAI

Exploitation The Live streaming plugin must be installed and active - this is an optional component, not part of the AVideo core. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H) is well-calibrated: the attack is fully unauthenticated, requires no special conditions, and yields high confidentiality impact via stream key exposure. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation The primary fix should be applied by upgrading AVideo to any version above 29.0 that addresses GHSA-8g4j-g3r6-73xr; however, an exact patched release version is not confirmed in the available data - verify the GitHub advisory at https://github.com/WWBN/AVideo/security/advisories/GHSA-8g4j-g3r6-73xr for the precise release. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: identify all AVideo instances running version 29.0 or earlier and confirm which deployments host the Live plugin with active streams. …
