{"cve":"CVE-2025-46827","nvd":{"published":"2025-05-07T16:15:22.720","modified":"2026-06-17T09:27:00.097","status":"Analyzed","description":"Graylog is a free and open log management platform. Prior to versions 6.0.14, 6.1.10, and 6.2.0, it is possible to obtain user session cookies by submitting an HTML form as part of an Event Definition Remediation Step field. For this attack to succeed, the attacker needs a user account with permissions to create event definitions, while the user must have permissions to view alerts. Additionally, an active Input must be present on the Graylog server that is capable of receiving form data (e.g. a HTTP input, TCP raw or syslog etc). Versions 6.0.14, 6.1.10, and 6.2.0 fix the issue. No known workarounds are available, as long as the relatively rare prerequisites are met.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4},"cwes":["CWE-79"],"references":["https://github.com/Graylog2/graylog2-server/security/advisories/GHSA-76vf-mpmx-777j"],"products":["graylog:graylog"],"source":"nvd","synced_at":"2026-10-19T22:01:22.920403922+00:00"},"epss":{"cve":"CVE-2025-46827","score":0.00287,"percentile":0.21234,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-76vf-mpmx-777j","url":"https://osv.dev/vulnerability/GHSA-76vf-mpmx-777j","summary":"Graylog Allows Session Takeover via Insufficient HTML Sanitization","modified":"2025-05-07T19:37:56.023640Z","packages":[{"ecosystem":"Maven","name":"org.graylog2:graylog2-server","purl":"pkg:maven/org.graylog2/graylog2-server","ranges":["<6.0.14"],"fixed":["6.0.14"]},{"ecosystem":"Maven","name":"org.graylog2:graylog2-server","purl":"pkg:maven/org.graylog2/graylog2-server","ranges":[">=6.1.0 <6.1.10"],"fixed":["6.1.10"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
