{"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":"2026-08-06T03:48:33.739629256Z","published":"2026-08-04T11:02:40.503Z","related":["CGA-mhwc-69g2-8cp8"],"database_specific":{"cna_assigner":"eclipse","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":[{"source":"AFFECTED_FIELD","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"}]}]},"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":"28100e8da711e44c0722ed10bd413ae862497539"},{"last_affected":"ae9286497b46fd709861e330fb364408a946d6e5"},{"introduced":"c8372b65bd15404de1444d68902c0455a3a69b64"},{"last_affected":"b1fb145d4b0ea34d7636012359604367f4de7496"}],"database_specific":{"extracted_events":[{"introduced":"12.0.0"},{"last_affected":"12.0.35"},{"introduced":"12.1.0"},{"last_affected":"12.1.9"}],"source":"AFFECTED_FIELD"}}],"versions":["jetty-12.0.35","jetty-12.1.9","jetty-12.1.5","jetty-12.0.31","jetty-12.1.4","jetty-12.0.30","jetty-12.1.2","jetty-12.0.23","jetty-12.1.0.beta1","jetty-12.0.22","jetty-12.0.19","jetty-12.0.15","jetty-12.0.14","jetty-12.0.6","jetty-12.0.5","jetty-12.0.0x"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/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"}]}
