{"id":"CVE-2025-30373","aliases":["GHSA-q7g5-jq6p-6wvx"],"url":"https://o3.security/vulnerability/CVE-2025-30373","summary":"Graylog Authenticated HTTP inputs do ingest message even if Authorization header is missing or has wrong value","details":"Graylog is a free and open log management platform. Starting with 6.1, HTTP Inputs can be configured to check if a specified header is present and has a specified value to authenticate HTTP-based ingestion. Unfortunately, even though in cases of a missing header or a wrong value the correct HTTP response (401) is returned, the message will be ingested nonetheless. To mitigate the vulnerability, disable http-based inputs and allow only authenticated pull-based inputs. This vulnerability is fixed in 6.1.9.","published":"2025-04-07T14:37:58.071Z","modified":"2026-08-08T09:38:21.664728Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.graylog2:graylog2-server","fixedVersion":"6.1.9"}],"fix":{"url":"https://github.com/Graylog2/graylog2-server/commit/31bc13d3cd6f550ec83473d0f8666cd3ebf50f10","label":"Graylog2/graylog2-server@31bc13d"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/30xxx/CVE-2025-30373.json"},{"type":"ADVISORY","url":"https://github.com/Graylog2/graylog2-server/security/advisories/GHSA-q7g5-jq6p-6wvx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-30373"},{"type":"FIX","url":"https://github.com/Graylog2/graylog2-server/commit/31bc13d3cd6f550ec83473d0f8666cd3ebf50f10"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T09:38:21.664728Z"}}
