CVE-2026-88875 — AVideo Incomplete API Sanitization Information Disclosure
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.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.3% (30-day exploitation probability)+3
- Technical severity (medium)+3
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Wwbn Avideo).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes, errors and authentication anomalies.
Affected scope
Vendor, product and versions as the sources word them.

What should defenders know first?
CVE-2026-88875 is "AVideo Incomplete API Sanitization Information Disclosure", rated Medium. It affects Avideo (Wwbn); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 4.3 describes technical severity. EPSS 0.31% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
