{"id":"UBUNTU-CVE-2026-10050","details":"In Eclipse Jetty, the Digest authentication server-side component uses ISO-8859-1 to encode the password as bytes. This was done because the initial specification for HTTP did not specify explicitly a charset, and it was assumed to be ISO-8859-1 for historical reasons. If the password contains characters that cannot be represented in ISO-8859-1, they are silently replaced by `?`. This happens with passwords that contain Chinese, Cyrillic or Greek characters, for example: `αβ123` converts to `??123`. An attacker can send a request with a digest `Authorization` header crafted with a password made of only `?` characters; the server would match any password of the same length that contains non-ISO-8859-1 characters. Recent HTTP Digest [RFC-7616](https://datatracker.ietf.org/doc/html/rfc7616) supports a `charset` parameters that defaults to UTF-8 that allows for correct encoding/decoding of passwords.","modified":"2026-08-10T09:45:12.154401284Z","published":"2026-08-04T11:22:00Z","upstream":["CVE-2026-10050"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-10050"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-10050"},{"type":"REPORT","url":"https://github.com/jetty/jetty.project/security/advisories/GHSA-2fvj-hgj9-j2gr"},{"type":"REPORT","url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/120"}],"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_name":"libjetty9-extra-java","binary_version":"9.2.14-1"},{"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-2026-10050.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_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","binary_version":"9.4.15-1~18.04.1ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-10050.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_name":"jetty9","binary_version":"9.4.26-1"},{"binary_name":"libjetty9-extra-java","binary_version":"9.4.26-1"},{"binary_name":"libjetty9-java","binary_version":"9.4.26-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-10050.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_name":"jetty9","binary_version":"9.4.45-1"},{"binary_version":"9.4.45-1","binary_name":"libjetty9-extra-java"},{"binary_name":"libjetty9-java","binary_version":"9.4.45-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-10050.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_name":"jetty9","binary_version":"9.4.53-1"},{"binary_name":"libjetty9-extra-java","binary_version":"9.4.53-1"},{"binary_name":"libjetty9-java","binary_version":"9.4.53-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-10050.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_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-2026-10050.json"}},{"package":{"name":"jetty9","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/jetty9?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.4.57-1","9.4.57-1.1","9.4.58-1"],"ecosystem_specific":{"binaries":[{"binary_version":"9.4.58-1","binary_name":"jetty9"},{"binary_name":"libjetty9-extra-java","binary_version":"9.4.58-1"},{"binary_name":"libjetty9-java","binary_version":"9.4.58-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-10050.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
