{"id":"UBUNTU-CVE-2026-94301","details":"The fix for CVE-2026-47065/ZDRES-232 (\"resolveProxyClass Not Overridden - acceptMatchers Filter Bypass via java.lang.reflect.Proxy\"), released on 2026-06-02 and announced as \"Fully addressed\" in MINA 2.2.8, 2.1.13 and 2.0.29, was committed to the  2.2.X branch only. The 2.0.X and 2.1.X maintenance branches never received the resolveProxyClass() override, so the 2.0.29 and 2.1.13 artifacts listed as fixed -- and every later release on those lines, up to and including the current 2.0.30 and 2.1.14 -- remain vulnerable to the exact allow-list bypass that CVE-2026-47065 was meant to close.","modified":"2026-09-24T02:03:14.121034529Z","published":"2026-09-21T15:17:00Z","upstream":["CVE-2026-94301"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-94301"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-94301"},{"type":"REPORT","url":"https://lists.apache.org/thread/rzos6zds5x7obl8trkvznt1djw4f996p"},{"type":"REPORT","url":"https://lists.apache.org/thread/x4667tn5ozbvkc3wz87lhzogbfl0dczj"}],"affected":[{"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-2026-94301.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_name":"libmina2-java","binary_version":"2.0.16-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94301.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_name":"libmina2-java","binary_version":"2.0.19-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94301.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-2026-94301.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":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94301.json"}},{"package":{"name":"mina2","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/ubuntu/mina2?arch=source&distro=esm-apps%2Fresolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.1-4","2.2.1-4ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"libmina2-java","binary_version":"2.2.1-4ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-94301.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
