CVE-2013-10075Network attack vector

Session revival via missing-record recreation

Published May 8, 2026 · Updated May 8, 2026

Insufficient session expiration in Apache::Session 1.94 and earlier allows remote attackers to revive deleted sessions through stale IDs. Apache::Session::Store::File and Apache::Session::Store::DB_File recreate a stored session when its requested identifier has no record, rather than treating it as absent. Exposure requires an application to use either affected store and accept a deleted session identifier; revived state can restore data intended for deletion.
