{"id":"CVE-2026-10050","summary":"Digest authentication lossy encoding","details":"In Eclipse Jetty, the Digest authentication server-side component uses ISO-8859-1 to encode the password as bytes.\n\n\n\nThis 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.\n\n\n\nIf 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`.\n\n\n\nAn 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.\n\n\n\nRecent 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.","aliases":["GHSA-2fvj-hgj9-j2gr"],"modified":"2026-09-08T03:46:07.700091974Z","published":"2026-08-04T11:02:40.503Z","related":["SUSE-SU-2026:3631-1","openSUSE-SU-2026:11505-1"],"database_specific":{"cwe_ids":["CWE-173","CWE-303"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/10xxx/CVE-2026-10050.json","unresolved_ranges":[{"extracted_events":[{"introduced":"9.4.0"},{"last_affected":"9.4.62"},{"introduced":"10.0.0"},{"last_affected":"10.0.30"},{"introduced":"11.0.0"},{"last_affected":"11.0.30"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"eclipse"},"references":[{"type":"WEB","url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/120"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/10xxx/CVE-2026-10050.json"},{"type":"ADVISORY","url":"https://github.com/jetty/jetty.project/security/advisories/GHSA-2fvj-hgj9-j2gr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-10050"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jetty/jetty.project","events":[{"introduced":"52d94174e2c7a6e794c6377dcf9cd3ed0b9e1806"},{"fixed":"e860638b60a1baac7f68130fd14bc7d18840e95e"},{"introduced":"c8372b65bd15404de1444d68902c0455a3a69b64"},{"fixed":"d7fcfb623d8dc0429b75cb7be2f4b9f0ffea6f52"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:eclipse:jetty:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"12.0.0"},{"fixed":"12.0.36"},{"introduced":"12.1.0"},{"fixed":"12.1.10"}]}}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-10050.json"}}],"schema_version":"1.9.0","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"}]}
