Network-accessible API requires only a low-privilege account (PR:L); confidentiality impact is partial (email, username, flags); no integrity or availability impact.

DescriptionCVE.org

AVideo through revision c3edcc274c389816d434acadac07ee78eaf330c1 (master, 2026-08-23) incompletely sanitizes sensitive user fields in the APIName=video response. Video rows include columns joined from the video owner's user record, and API::get_api_video() calls removeSensitiveUserFields() only when the caller is neither authenticated nor using a valid API secret; it never compares User::getId() with the row's users_id. As a result, any low-privilege authenticated account can request another user's video and receive the owner's email address, account name (user), and isAdmin, canUpload and canStream flags, which are removed for guests and should be returned only to the owner or to callers with a valid API secret. No patched version was available at the time of the advisory.

AnalysisAI

Incomplete authorization logic in AVideo's video API endpoint exposes private user account fields to any authenticated low-privilege user. The API::get_api_video() method calls removeSensitiveUserFields() only when the caller is a guest or lacks a valid API secret, but never compares the authenticated caller's user ID against the video row's users_id column. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid low-privilege authenticated session on the target AVideo instance - the attacker must hold any registered account. … 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:L/UI:N/VC:L/VI:N/VA:N) accurately reflects the limited but concrete confidentiality impact: network-reachable, trivially exploitable by any registered user, no special conditions required. … 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 No vendor-released patched version was identified at time of analysis; organizations should monitor https://github.com/WWBN/AVideo/security/advisories/GHSA-qwp4-vh4w-2fh9 for an upstream fix. … Detailed patch versions, workarounds, and compensating controls in full report.
