CVE-2026-62379
OpenAM: Unauthenticated Remote Code Execution via Class.forName in AuthXMLUtils.createCustomCallback
Summary
## Summary A pre-authentication remote code execution vulnerability affects OpenAM. The remote authentication endpoint (`/authservice`, PLL) accepts an XML element that names an arbitrary Java class, which the server then loads and instantiates without validation. On a default configuration this is reachable **without authentication** and allows an attacker to run code on the server. ## Impact Unauthenticated remote code execution / full server compromise on any OpenAM instance with default settings. ## Affected All releases up to and including 16.1.1 (the defect predates the Open Identity Platform fork). ## Remediation Upgrade to `16.1.2`. ## Interim mitigation - Require the remote-auth security token by enabling `sunRemoteAuthSecurityEnabled` (rejects unauthenticated `/authservice` calls). - Restrict or block external network access to `/authservice` until patched. ## Credit Vulnerability discovered by Zhixi "Jace" Sun of ASM/VI at TikTok.
