In Ghost versions 5.43.0 through 5.12.04 and 6.0.0 through 6.14.0, an attacker was able to craft a malicious link that, when accessed by an authenticated staff user or member, would execute JavaScript with the victim's permissions, potentially leading to account takeover. Ghost Portal versions 2.29.1 through 2.51.4 and 2.52.0 through 2.57.0 were vulnerable to this issue. Ghost automatically loads the latest patch of the members Portal component via CDN. For Ghost 5.x users, upgrading to v5.121.0 or later fixes the vulnerability. v5.121.0 loads Portal v2.51.5, which contains the patch. For Ghost 6.x users, upgrading to v6.15.0 or later fixes the vulnerability. v6.15.0 loads Portal v2.57.1, which contains the patch. For Ghost installations using a customized or self-hosted version of Portal, it will be necessary to manually rebuild from or update to the latest patch version.","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/TryGhost/Ghost/commit/da858e640e88e69c1773a7b7ecdc2008fa143849","https://github.com/TryGhost/Ghost/security/advisories/GHSA-gv6q-2m97-882h"],"products":["ghost:ghost","ghost:portal"],"source":"nvd","synced_at":"2026-10-19T22:21:16.563232421+00:00"},"epss":{"cve":"CVE-2026-24778","score":0.00287,"percentile":0.21274,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-gv6q-2m97-882h","url":"https://osv.dev/vulnerability/GHSA-gv6q-2m97-882h","summary":"Ghost vulnerable to XSS via malicious Portal preview links","modified":"2026-02-03T09:26:16.637328Z","packages":[{"ecosystem":"npm","name":"ghost","purl":"pkg:npm/ghost","ranges":[">=5.43.0 <5.121.0"],"fixed":["5.121.0"]},{"ecosystem":"npm","name":"@tryghost/portal","purl":"pkg:npm/%40tryghost/portal","ranges":[">=2.29.1 <2.51.5"],"fixed":["2.51.5"]},{"ecosystem":"npm","name":"@tryghost/portal","purl":"pkg:npm/%40tryghost/portal","ranges":[">=2.52.0 <2.57.1"],"fixed":["2.57.1"]},{"ecosystem":"npm","name":"ghost","purl":"pkg:npm/ghost","ranges":[">=6.0.0 <6.15.0"],"fixed":["6.15.0"]}]}],"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).
