{"id":"CVE-2023-49802","summary":"MantisBT LinkedCustomFields Cross-site Scripting vulnerability","details":"The LinkedCustomFields plugin for MantisBT allows users to link values between two custom fields, creating linked drop-downs. Prior to version 2.0.1, cross-site scripting in the MantisBT LinkedCustomFields plugin allows Javascript execution, when a crafted Custom Field is linked via the plugin and displayed when reporting a new Issue or editing an existing one. This issue is fixed in version 2.0.1. As a workaround, one may utilize MantisBT's default Content Security Policy, which blocks script execution.","aliases":["GHSA-2f37-9xpx-5hhw"],"modified":"2026-08-12T03:51:32.651716003Z","published":"2023-12-11T21:11:53.407Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/49xxx/CVE-2023-49802.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-79"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/49xxx/CVE-2023-49802.json"},{"type":"ADVISORY","url":"https://github.com/mantisbt-plugins/LinkedCustomFields/security/advisories/GHSA-2f37-9xpx-5hhw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-49802"},{"type":"REPORT","url":"https://github.com/mantisbt-plugins/LinkedCustomFields/issues/10"},{"type":"FIX","url":"https://github.com/mantisbt-plugins/LinkedCustomFields/commit/30e5ae751e40d7ae18bfd794fd48671477b3d286"},{"type":"FIX","url":"https://github.com/mantisbt-plugins/LinkedCustomFields/pull/11"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mantisbt-plugins/linkedcustomfields","events":[{"introduced":"0"},{"fixed":"100b571323d504b7a1a59ad76050e5168c5957a3"},{"fixed":"30e5ae751e40d7ae18bfd794fd48671477b3d286"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:mantisbt:linked_custom_fields:*:*:*:*:*:mantisbt:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2.0.1"}]}}],"versions":["v2.0.0","v1.0.1","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-49802.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:L"}]}
