CVE-2026-33684: CWE-862: Missing Authorization in WWBN AVideo
WWBN AVideo versions prior to 29.0 contain a missing authorization vulnerability in the signUp API that allows privilege escalation. Attackers who can solve a CAPTCHA can self-assign elevated permissions such as emailVerified, canUpload, canStream, and canCreateMeet during account registration without proper authentication. This bypasses intended access controls and allows unauthorized capabilities. The issue is fixed in version 29.0.
AI Analysis
Technical Summary
CVE-2026-33684 describes a missing authorization vulnerability (CWE-862) in WWBN AVideo's signUp API prior to version 29.0. The API method set_api_signUp improperly accepts user-supplied parameters for emailVerified, canUpload, canStream, and canCreateMeet without verifying the request is authenticated with a valid APISecret. This allows any user who passes a CAPTCHA to escalate privileges by self-granting these permissions during account creation, circumventing administrator restrictions. The vulnerability is resolved in version 29.0.
Potential Impact
An attacker can escalate privileges during account registration by self-assigning elevated permissions, including marking their account as email-verified and enabling upload, streaming, and meeting creation capabilities. This undermines access controls and potentially allows unauthorized use of restricted platform features. There is no direct confidentiality or availability impact reported. The CVSS v3.1 base score is 5.3 (medium severity).
Mitigation Recommendations
Upgrade WWBN AVideo to version 29.0 or later, where this vulnerability is fixed. Patch status is confirmed by the vendor stating the issue is resolved in version 29.0. Until upgrading, restrict access to the signUp API or implement additional verification to prevent unauthorized parameter manipulation.
