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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://github.com/mantisbt-plugins/LinkedCustomFields/commit/30e5ae751e40d7ae18bfd794fd48671477b3d286","https://github.com/mantisbt-plugins/LinkedCustomFields/issues/10","https://github.com/mantisbt-plugins/LinkedCustomFields/pull/11","https://github.com/mantisbt-plugins/LinkedCustomFields/security/advisories/GHSA-2f37-9xpx-5hhw","https://github.com/mantisbt-plugins/LinkedCustomFields/commit/30e5ae751e40d7ae18bfd794fd48671477b3d286"],"products":["mantisbt:linked_custom_fields"],"source":"nvd","synced_at":"2026-10-19T21:42:34.585441961+00:00"},"epss":{"cve":"CVE-2023-49802","score":0.0066,"percentile":0.51583,"date":"2026-10-31"},"kev":null,"osv":[],"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).
