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"}], "source": {"advisory": "GHSA-8j8m-p79x-g4jm", "discovery": "UNKNOWN"}}}}
