CVE-2026-72561Network attack vector

Credential harvesting via unauthorized OIDC issuer change

Published Aug 11, 2026 · Updated Aug 11, 2026

Broken access control in Peppermint through commit ba6e217 allows remote authenticated users to replace the platform's global OIDC issuer. The global settings endpoint applies attacker-supplied OIDC/SSO settings without verifying that the caller has an administrative role. Any non-administrative account can redirect later SSO logins to an attacker-controlled identity provider and harvest platform credentials.
