CVE-2026-72561: Peppermint Lab Peppermint

High severity, CVSS 8.8. EPSS: 0.4% chance of exploitation in the next 30 days.

A broken access control vulnerability in Peppermint Lab Peppermint through commit ba6e217 allows any authenticated non-administrative user to reconfigure the platform global OIDC/SSO settings via an unprotected configuration endpoint. The endpoint performs no administrative role check before applying new OIDC issuer settings. An attacker can redirect all SSO logins to an attacker-controlled identity provider, enabling credential harvesting for all platform users.
