Technical description

WWBN AVideo is an open source video platform. Prior to version 29.0, Privilege Escalation is possible through unguarded permission parameters in signUp API, which allows any user who can solve a CAPTCHA to self-grant elevated permissions during account registration. The set_api_signUp method in the API plugin accepts emailVerified, canUpload, canStream, and canCreateMeet parameters from user-supplied input and applies them to newly created accounts without verifying that the request was authenticated with a valid APISecret. By self-granting account attributes, attackers can mark their own accounts as email-verified without owning the address (bypassing email-gated functionality) and award themselves upload, streaming, and meeting-creation permissions, circumventing administrator access controls that intentionally restrict these capabilities for new users. This issue has been fixed in version 29.0

Remediation
