description

VibeBP versions through 1.9.9.8.1 are affected by an authorization flaw in user metadata updates. An authenticated user with at least Subscriber permissions may elevate their own account to administrator; access to such an account is required.

mitigation

Disable VibeBP or restrict untrusted Subscriber and other low-privilege accounts until a vendor-fixed release is available. Monitor user-role changes and revoke unexpected administrator privileges.

outcome

Upstream: a detection for this already ships elsewhere, so we didn't generate a new one. The credit goes to whoever did.
