1) Missing Authorization (CVE-ID: CVE-2026-33684)

CWE-ID: CWE-862 - Missing Authorization

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to self-grant upload, streaming, and meeting creation permissions and bypass email verification.

The vulnerability exists due to missing authorization in AVideo's API plugin set_api_signUp method when applying user-supplied account permissions without validating APISecret. A remote attacker can submit a registration request with a valid CAPTCHA and emailVerified=1, canUpload=1, canStream=1, and canCreateMeet=1 to create an account with elevated permissions and verified email status.
