CVE-2026-72561: CWE-284: Improper Access Control in Peppermint Lab Peppermint
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.
AI Analysis
Technical Summary
This vulnerability arises from improper access control in Peppermint Lab Peppermint, specifically through a commit identified as ba6e217. The affected configuration endpoint does not verify if the user has administrative privileges before allowing changes to the platform's global OIDC/SSO settings. As a result, any authenticated user without admin rights can reconfigure the SSO issuer to an attacker-controlled identity provider, facilitating credential harvesting for all users relying on SSO authentication.
Potential Impact
An attacker with any authenticated user privileges can exploit this vulnerability to redirect all SSO login attempts to an attacker-controlled identity provider. This can lead to widespread credential harvesting, compromising the confidentiality and integrity of user credentials and potentially allowing full platform compromise. The CVSS score of 8.8 reflects high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the configuration endpoint to trusted administrators only, if possible, and monitor for unauthorized changes to OIDC/SSO settings.
