What is CVE-2026-34574?

An issue exists in Parse Server, where authenticated users can bypass session immutability guards by sending a null value in a PUT request to the session update endpoint. This vulnerability allows attackers to nullify the session expiry, making an active session valid indefinitely and circumventing the configured session length policies. This flaw impacts versions prior to 8.6.69 and 9.7.0-alpha.14. The offending versions have since been patched to close this security loophole.

parse-server < 8.6.69 < 8.6.69

parse-server >= 9.0.0, < 9.7.0-alpha.14 < 9.0.0, 9.7.0-alpha.14
