Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-46827 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.graylog2:graylog2-server (Maven): affected all versions; fixed in 6.0.14\n- org.graylog2:graylog2-server (Maven): affected all versions; fixed in 6.0.14\n- org.graylog2:graylog2-server (Maven): affected from 6.1.0; fixed in 6.1.10\n- org.graylog2:graylog2-server (Maven): affected from 6.1.0; fixed in 6.1.10\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-46827/ (Markdown: https://insights.sbomify.com/CVE-2025-46827/index.md)","id":"CVE-2025-46827","markdown":"https://insights.sbomify.com/CVE-2025-46827/index.md","name":"CVE-2025-46827","record":{"aliases":["GHSA-76vf-mpmx-777j"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"Graylog log management","requires_auth":"low_privilege","summary":"Attackers can steal session cookies via HTML injection in event definitions, requiring specific permissions and active inputs.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"graylog","vendor":"graylog"}],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"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.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Graylog Allows Session Takeover via Insufficient HTML Sanitization","id":"CVE-2025-46827","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xss","year":"2025"},"n_packages":4,"n_references":1,"next":{"headline":"Unauthenticated SQL Injection on get_socios.php endpoint","id":"CVE-2025-46828"},"packages":[{"ecosystem":"Maven","fixed":["6.0.14"],"introduced":["0"],"last_affected":[],"package":"org.graylog2:graylog2-server","purl":null,"source":"GHSA-76vf-mpmx-777j"},{"ecosystem":"Maven","fixed":["6.0.14"],"introduced":["0"],"last_affected":[],"package":"org.graylog2:graylog2-server","purl":"pkg:maven/org.graylog2/graylog2-server","source":"GHSA-76vf-mpmx-777j"},{"ecosystem":"Maven","fixed":["6.1.10"],"introduced":["6.1.0"],"last_affected":[],"package":"org.graylog2:graylog2-server","purl":null,"source":"GHSA-76vf-mpmx-777j"},{"ecosystem":"Maven","fixed":["6.1.10"],"introduced":["6.1.0"],"last_affected":[],"package":"org.graylog2:graylog2-server","purl":"pkg:maven/org.graylog2/graylog2-server","source":"GHSA-76vf-mpmx-777j"}],"prev":{"headline":"insa-auth Open-Redirect on provided CAS server login endpoint","id":"CVE-2025-46826"},"products":["graylog2-server"],"published":"2025-05-07","related":[{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2021-37759","kev_date_added":null,"published":"2021-07-31"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2021-37760","kev_date_added":null,"published":"2021-07-31"},{"cvss_score":9.3,"headline":"Incorrect management of session invalidation vulnerability in Graylog Web Interface","id":"CVE-2026-1435","kev_date_added":null,"published":"2026-02-18"},{"cvss_score":8.8,"headline":"Graylog vulnerable to privilege escalation through API tokens","id":"CVE-2025-53106","kev_date_added":null,"published":"2025-07-02"},{"cvss_score":8.8,"headline":"graylog2-server vulnerable to instantiation of arbitrary classes triggered by API request","id":"CVE-2024-24824","kev_date_added":null,"published":"2024-02-07"},{"cvss_score":8.1,"headline":"Improper Certificate Validation in Graylog","id":"CVE-2020-15813","kev_date_added":null,"published":"2020-07-17"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-05-07","vendors":["Graylog2"]},"summary":"Attackers can steal session cookies via HTML injection in event definitions, requiring specific permissions and active inputs.","url":"https://insights.sbomify.com/CVE-2025-46827/"}
