- mina2 - Apache MINA is a network application framework which helps users develop high performance and high scalability network applications easily
Details
It was discovered that Apache MINA lacked an acceptMatchers allowlist
mechanism to restrict which classes could be deserialized. An attacker
could use this to execute arbitrary code. This issue only affected
Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-52046)
It was discovered that Apache MINA's deserialization filter could be
bypassed via multiple code paths. An attacker could use this to execute
arbitrary code by sending a specially crafted serialized object over the
network. (CVE-2026-42778, CVE-2026-42779, CVE-2026-47065)
