CVE-2025-35433Network attack vector

Persistent access via unsaved token rotation

Published Sep 17, 2025 · Updated Sep 17, 2025

Insufficient session expiration in CISA Thorium before 1.1.1 allows remote authenticated users to retain account access after a reset. The password-update path generates a replacement token but fails to save it, leaving the previously issued token valid. A previously authenticated token and an LDAP-enabled cluster are required; the token continues to authorize API access after the account password changes.
