{"id":"UBUNTU-CVE-2026-118636","details":"**UNSUPPORTED WHEN ASSIGNED** JavaNativeMessageDecoder in the MINA 3.0 codec module calls ObjectInputStream.readObject() on frame bytes with no class filter, so an application that puts it in front of an untrusted peer is open to gadget-chain RCE. As the 3.0.0 branch is inactive, we do not plan to release a version that fixes this issue. Users are recommended to use the latest Apache MINA 2.2.X branch.","modified":"2026-11-04T03:30:27.065867517Z","published":"2026-11-03T00:00:00Z","upstream":["CVE-2026-118636"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-118636"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-118636"},{"type":"REPORT","url":"https://lists.apache.org/thread.html/h76nwcrkvsffhsk2kq6cjzc6srtnty7x"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-118636"},{"type":"REPORT","url":"http://www.openwall.com/lists/oss-security/2026/10/31/3"}],"affected":[{"package":{"name":"mina","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/mina?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.7.dfsg-11"],"ecosystem_specific":{"binaries":[{"binary_name":"libmina-java","binary_version":"1.1.7.dfsg-11"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-118636.json"}},{"package":{"name":"mina2","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/mina2?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.7+dfsg-2","2.0.9-1","2.0.9-2"],"ecosystem_specific":{"binaries":[{"binary_name":"libmina2-java","binary_version":"2.0.9-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-118636.json"}},{"package":{"name":"mina","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/mina?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.7.dfsg-11","1.1.7.dfsg-12"],"ecosystem_specific":{"binaries":[{"binary_name":"libmina-java","binary_version":"1.1.7.dfsg-12"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-118636.json"}},{"package":{"name":"mina2","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/mina2?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.16-2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.0.16-2","binary_name":"libmina2-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-118636.json"}},{"package":{"name":"mina","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/mina?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.7.dfsg-13"],"ecosystem_specific":{"binaries":[{"binary_name":"libmina-java","binary_version":"1.1.7.dfsg-13"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-118636.json"}},{"package":{"name":"mina2","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/mina2?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.19-2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.0.19-2","binary_name":"libmina2-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-118636.json"}},{"package":{"name":"mina","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/mina?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.7.dfsg-13"],"ecosystem_specific":{"binaries":[{"binary_version":"1.1.7.dfsg-13","binary_name":"libmina-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-118636.json"}},{"package":{"name":"mina2","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/mina2?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.4-2","2.1.5-1","2.1.5-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmina2-java","binary_version":"2.1.5-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-118636.json"}},{"package":{"name":"mina","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/mina?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.7.dfsg-13","1.1.7.dfsg-13ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmina-java","binary_version":"1.1.7.dfsg-13ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-118636.json"}},{"package":{"name":"mina2","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/mina2?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.1-3","2.2.1-3ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmina2-java","binary_version":"2.2.1-3ubuntu0.1~esm1"}]},"database_specific":{"source":"htt
