{"cve":"CVE-2024-52506","nvd":{"published":"2024-11-18T21:15:06.633","modified":"2026-06-17T08:07:21.140","status":"Analyzed","description":"Graylog is a free and open log management platform. The reporting functionality in Graylog allows the creation and scheduling of reports which contain dashboard widgets displaying individual log messages or metrics aggregated from fields of multiple log messages. This functionality, as included in Graylog 6.1.0 & 6.1.1, is vulnerable to information leakage triggered by multiple concurrent report rendering requests from authorized users. When multiple report renderings are requested at the same start time, the headless browser instance used to render the PDF will be reused. Depending on the timing, either a check for the browser instance \"freshness\" hits, resulting in an error instead of the report being returned, or one of the concurrent report rendering requests \"wins\" and this report is returned for all report rendering requests that do not return an error. This might lead to one user getting the report of a different user, potentially leaking indexed log messages or aggregated data that this user normally has no access to. This problem is fixed in Graylog 6.1.2. There is no known workaround besides disabling the reporting functionality.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-200"],"references":["https://github.com/Graylog2/graylog2-server/security/advisories/GHSA-vggm-3478-vm5m","https://www.vicarius.io/vsociety/posts/cve-2024-52506-detect-graylog-vulnerability","https://www.vicarius.io/vsociety/posts/cve-2024-52506-mitigate-graylog-vulnerability"],"products":["graylog:graylog"],"source":"nvd","synced_at":"2026-10-19T21:57:34.731061660+00:00"},"epss":{"cve":"CVE-2024-52506","score":0.00632,"percentile":0.50333,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-vggm-3478-vm5m","url":"https://osv.dev/vulnerability/GHSA-vggm-3478-vm5m","summary":"Graylog concurrent PDF report rendering can leak other users' reports","modified":"2025-09-23T22:26:50.467581Z","packages":[{"ecosystem":"Maven","name":"org.graylog:graylog-parent","purl":"pkg:maven/org.graylog/graylog-parent","ranges":[">=6.1.0 <6.1.2"],"fixed":["6.1.2"]}]}],"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).
