{"id":"CVE-2025-11143","aliases":["GHSA-wjpw-4j6x-6rwh"],"url":"https://o3.security/vulnerability/CVE-2025-11143","summary":"org.eclipse.jetty:jetty-http has different parsing of invalid URIs","details":"The Jetty URI parser has some key differences compared to other common parsers when evaluating invalid or unusual URIs. Specifically:\n\n#### Invalid Scheme\n| URI | Jetty | uri-js (nodejs) | node-url(nodejs) |\n|---|---|---| --- |\n| `https>://vulndetector.com/path` | scheme=`http>`| scheme=`https` | invalid URI |\n\n#### Improper IPv4 mapped IPv6\n\n| URI | Jetty | System.Uri(CSharp) | curl(C) |\n|---|---|---| --- |\n| `http://[0:0:0:0:0:ffff:127.0.0.1]` | invalid | host=`[::ffff:127.0.0.1]` | host=`[::ffff:127.0.0.1]` | \n| `http://[::ffff:255.255.0.0]` | invalid | host=`[::ffff:255.255.0.0]` | host=`[::ffff:255.255.0.0]` | \n\n#### Incorrect IPv6 delimeter priority\n\n| URI | Jetty | urllib3(python) | furl(python) | Spring | chromium |\n|---|---|---| --- |---|---|\n| `http://[normal.com@]vulndetector.com/` | host=`[normal.com@]` | invalid | invalid | | |\n| `http://normal.com[user@vulndetector].com/`  | host=`[noirmal.com@vulndetector | | | host=`normal.com` | invalid |\n| `http://normal.com[@]vulndetector.com/`  | host=`normal.com[@] | | | host=`normal.com` | invalid |\n\n#### Incorrect delimeter priority\n\n| URI | Jetty | urllib3(python) | jersey |\n|---|---|---| --- |\n| `http://normal.com/#@vulndetector.com` | host=`vulndetector.com` | host=`normal.com` | host=`normal.com` |\n| `http://normal.com/?@vulndetector.com` | host=`vulndetector.com` | host=`normal.com` | host=`normal.com` |\n\n\n### Impact\nDifferential parsing of URIs in systems using multiple components may result in security by-pass. For example a component that enforces a black list may interpret the URIs differently from one that generates a response.\nAt the very least, differential parsing may divulge implementation details. \n\n### Patches\nPatched in Supported Open Source versions.\n* 12.1.5 - Supported and available on Maven Central\n* 12.0.31 - Supported and available on Maven Central\n* 11.0.x  - EOL Release, patches available on [tuxcare](https://tuxcare.com/) and [herodevs](https://www.herodevs.com/)\n* 10.0.x  - EOL Release, patches available on [tuxcare](https://tuxcare.com/) and [herodevs](https://www.herodevs.com/)\n* 9.4.x - EOL Release, patches available on [tuxcare](https://tuxcare.com/) and [herodevs](https://www.herodevs.com/)\n\n### Workarounds\nNone\n\n### Resources\n\n + [Java Eclipse Jetty Report_ Incorrect Parsing Priority of the IPv6 Hostname Delimeter.pdf](https://github.com/user-attachments/files/22222625/Java.Eclipse.Jetty.Report_.Incorrect.Parsing.Priority.of.the.IPv6.Hostname.Delimeter.pdf)\n + [Java Eclipse Jetty Report_ The Parsing Priority of the Delimiter.pdf](https://github.com/user-attachments/files/22222626/Java.Eclipse.Jetty.Report_.The.Parsing.Priority.of.the.Delimiter.pdf)\n + [Java Eclipse Jetty Report_ Parsing Difference Due to Deformed Scheme.pdf](https://github.com/user-attachments/files/22222627/Java.Eclipse.Jetty.Report_.Parsing.Difference.Due.to.Deformed.Scheme.pdf)\n + [Java Eclipse Jetty Report_ Improper IPv4-mapped IPv6 Parsing.pdf](https://github.com/user-attachments/files/22222630/Java.Eclipse.Jetty.Report_.Improper.IPv4-mapped.IPv6.Parsing.pdf)","published":"2026-03-05T09:26:59.830Z","modified":"2026-09-06T03:45:12.736671720Z","cvss":{"score":3.7,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N"},"epss":{"score":0.00159,"percentile":0.05227,"asOf":"2026-08-26"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.eclipse.jetty:jetty-http","fixedVersion":null},{"ecosystem":"Maven","name":"org.eclipse.jetty:jetty-http","fixedVersion":null},{"ecosystem":"Maven","name":"org.eclipse.jetty:jetty-http","fixedVersion":null},{"ecosystem":"Maven","name":"org.eclipse.jetty:jetty-http","fixedVersion":"12.0.31"},{"ecosystem":"Maven","name":"org.eclipse.jetty:jetty-http","fixedVersion":"12.1.5"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/11xxx/CVE-2025-11143.json"},{"type":"ADVISORY","url":"https://github.com/jetty/jetty.project/security/advisories/GHSA-wjpw-4j6x-6rwh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-11143"},{"type":"PACKAGE","url":"https://github.com/jetty/jetty.project"},{"type":"WEB","url":"https://github.com/user-attachments/files/22222625/Java.Eclipse.Jetty.Report_.Incorrect.Parsing.Priority.of.the.IPv6.Hostname.Delimeter.pdf"},{"type":"WEB","url":"https://github.com/user-attachments/files/22222626/Java.Eclipse.Jetty.Report_.The.Parsing.Priority.of.the.Delimiter.pdf"},{"type":"WEB","url":"https://github.com/user-attachments/files/22222627/Java.Eclipse.Jetty.Report_.Parsing.Difference.Due.to.Deformed.Scheme.pdf"},{"type":"WEB","url":"https://github.com/user-attachments/files/22222630/Java.Eclipse.Jetty.Report_.Improper.IPv4-mapped.IPv6.Parsing.pdf"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-06T03:45:12.736671720Z"}}
