{"id":"UBUNTU-CVE-2026-19864","details":"Eclipse Jetty's `SessionAuthentication` retains authentication credentials in a serializable object. When the credentials contain a plaintext password and the authenticated session is persisted to a session data store, the password may consequently be written to persistent storage in plaintext. An attacker with sufficient privileges to read the persisted session data may obtain the plaintext passwords of authenticated users.","modified":"2026-10-17T12:58:46.514352920Z","published":"2026-10-16T00:00:00Z","upstream":["CVE-2026-19864"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-19864"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-19864"},{"type":"REPORT","url":"https://github.com/jetty/jetty.project/security/advisories/GHSA-q6wx-j9wr-fj7f"},{"type":"REPORT","url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/229"}],"affected":[{"package":{"name":"jetty9","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/jetty9?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.2.14-1"],"ecosystem_specific":{"binaries":[{"binary_name":"jetty9","binary_version":"9.2.14-1"},{"binary_version":"9.2.14-1","binary_name":"libjetty9-extra-java"},{"binary_name":"libjetty9-java","binary_version":"9.2.14-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-19864.json"}},{"package":{"name":"jetty9","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/jetty9?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.2.22-2","9.2.22-3","9.2.23-1","9.4.15-1~18.04.1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"9.4.15-1~18.04.1ubuntu1","binary_name":"jetty9"},{"binary_version":"9.4.15-1~18.04.1ubuntu1","binary_name":"libjetty9-extra-java"},{"binary_version":"9.4.15-1~18.04.1ubuntu1","binary_name":"libjetty9-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-19864.json"}},{"package":{"name":"jetty9","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/jetty9?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.4.18-2build2","9.4.26-1"],"ecosystem_specific":{"binaries":[{"binary_version":"9.4.26-1","binary_name":"jetty9"},{"binary_name":"libjetty9-extra-java","binary_version":"9.4.26-1"},{"binary_version":"9.4.26-1","binary_name":"libjetty9-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-19864.json"}},{"package":{"name":"jetty9","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/jetty9?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.4.39-3","9.4.44-2","9.4.44-3","9.4.44-4","9.4.45-1"],"ecosystem_specific":{"binaries":[{"binary_version":"9.4.45-1","binary_name":"jetty9"},{"binary_version":"9.4.45-1","binary_name":"libjetty9-extra-java"},{"binary_version":"9.4.45-1","binary_name":"libjetty9-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-19864.json"}},{"package":{"name":"jetty9","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/jetty9?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.4.51-2","9.4.53-1"],"ecosystem_specific":{"binaries":[{"binary_version":"9.4.53-1","binary_name":"jetty9"},{"binary_version":"9.4.53-1","binary_name":"libjetty9-extra-java"},{"binary_version":"9.4.53-1","binary_name":"libjetty9-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-19864.json"}},{"package":{"name":"jetty12","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/jetty12?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["12.0.32-1"],"ecosystem_specific":{"binaries":[{"binary_name":"jetty12","binary_version":"12.0.32-1"},{"binary_name":"libjetty12-extra-java","binary_version":"12.0.32-1"},{"binary_name":"libjetty12-java","binary_version":"12.0.32-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-19864.json"}},{"package":{"name":"jetty9","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/jetty9?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.4.58-1","9.4.58-2"],"ecosystem_specific":{"binaries":[{"binary_name":"jetty9","binary_version":"9.4.58-2"},{"binary_name":"libjetty9-extra-java","binary_version":"9.4.58-2"},{"binary_version":"9.4.58-2","binary_name":"libjetty9-java"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-19864.json"}},{"package":{"name":"jetty12","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/jetty12?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["12.0.17-3.1","12.0.32-1"],"ecosystem_specific":{"binaries":[{"binary_name":"jetty12","binary_version":"12.0.32-1"},{"binary_version":"12.0.32-1","binary_name":"libjetty12-extra-java"},{"binary_name":"libjetty12-java","binary_version":"12.0.3
