Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache MINA mina-core versions 2.1.0 to before 2.1.12 and 2.2.0 to before 2.2.7 are vulnerable to unsafe deserialization of untrusted data, because an earlier fix for CVE-2026-41635 was not applied to these branches. An attacker who can supply serialized data that an application reads through IoBuffer.getObject() can bypass the class allowlist and may execute arbitrary code. Users should upgrade mina-core to 2.1.12 or 2.2.7.
