{"id":"CVE-2025-1948","aliases":["GHSA-889j-63jv-qhr8"],"url":"https://o3.security/vulnerability/CVE-2025-1948","summary":"Eclipse Jetty HTTP clients can increase memory allocation","details":"### Original Report\n\nIn Eclipse Jetty versions 12.0.0 to 12.0.16 included, an HTTP/2 client can specify a very large value for the HTTP/2 settings parameter SETTINGS_MAX_HEADER_LIST_SIZE. The Jetty HTTP/2 server does not perform validation on this setting, and tries to allocate a ByteBuffer of the specified capacity to encode HTTP responses, likely resulting in OutOfMemoryError being thrown, or even the JVM process exiting.\n\n### Impact\nRemote peers can cause the JVM to crash or continuously report OOM.\n\n### Patches\n12.0.17\n\n### Workarounds\nNo workarounds.\n\n### References\nhttps://github.com/jetty/jetty.project/issues/12690","published":"2025-05-08T17:48:40.831Z","modified":"2026-09-06T03:45:46.206292268Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.00748,"percentile":0.52113,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.eclipse.jetty.http2:jetty-http2-common","fixedVersion":"12.0.17"}],"fix":{"url":"https://github.com/jetty/jetty.project/commit/c8c2515936ef968dc8a3cecd9e79d1e69291e4bb","label":"jetty/jetty.project@c8c2515"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/1xxx/CVE-2025-1948.json"},{"type":"ADVISORY","url":"https://github.com/jetty/jetty.project/security/advisories/GHSA-889j-63jv-qhr8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-1948"},{"type":"REPORT","url":"https://gitlab.eclipse.org/security/cve-assignement/-/issues/56"},{"type":"WEB","url":"https://github.com/jetty/jetty.project/issues/12690"},{"type":"WEB","url":"https://github.com/jetty/jetty.project/commit/c8c2515936ef968dc8a3cecd9e79d1e69291e4bb"},{"type":"PACKAGE","url":"https://github.com/jetty/jetty.project"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-06T03:45:46.206292268Z"}}
