{"id":"DEBIAN-CVE-2026-47065","details":"ZDRES-232: resolveProxyClass Not Overridden - acceptMatchers Filter Bypass via java.lang.reflect.Proxy   Assessment: Fully addressed.   When the serialised stream contains a TC_PROXYCLASSDESC (the marker  for a java.lang.reflect.Proxy ), JDK’s ObjectInputStream.readProxyDesc()  is dispatched. JDK then calls the default  ObjectInputStream.resolveProxyClass(interfaces) implementation, which  performs Class.forName(intf, false, latestUserDefinedLoader()) for EACH  interface name and constructs the proxy class — bypassing the accepted  classes list .   ZDRES-233: Class.forName(name, initialize=true, classLoader) in  readClassDescriptor Triggers Static Initialiser of Allow-Listed Classes   Assessment: Fully addressed.   For ANY class on the allow-list, deserialising a stream that names it triggers the class’s   (static initialiser) BEFORE any instance is constructed. This means an  attacker who supplies a class name on the allow-list (e.g., the  developer wrote accept(“com.myapp.*\") , attacker supplies  com.myapp.SomeClass ) causes \u003cclinit\u003e of SomeClass — and many  real-world classes have side-effecting static initialisers   Both issues have been fixed.","modified":"2026-09-01T16:06:47.247291105Z","published":"2026-06-03T11:16:19.800Z","upstream":["CVE-2026-47065"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-47065"}],"affected":[{"package":{"name":"mina","ecosystem":"Debian:12","purl":"pkg:deb/debian/mina?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.7.dfsg-13","1.1.7.dfsg-14"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-47065.json"}},{"package":{"name":"mina2","ecosystem":"Debian:12","purl":"pkg:deb/debian/mina2?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.1-3","2.2.1-4","2.2.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-47065.json"}},{"package":{"name":"mina2","ecosystem":"Debian:13","purl":"pkg:deb/debian/mina2?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.1-4","2.2.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-47065.json"}},{"package":{"name":"mina2","ecosystem":"Debian:14","purl":"pkg:deb/debian/mina2?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.2.9-1"}]}],"versions":["2.2.1-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-47065.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"}]}
