Version 4.29.0 has a stored cross-site scripting vulnerability in the image widget functionality. A user with the Editor role can configure an image widget link to use a javascript: URL payload. Because editors have permission to publish pages, the malicious widget can be published to the live site. When another user, including an administrator or public visitor, clicks the affected image/link, arbitrary JavaScript executes in the victim’s browser. As of time of publication, no known patched versions are available.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N","score":7.3},"cwes":["CWE-79","CWE-116"],"references":["https://github.com/apostrophecms/apostrophe/releases/tag/apostrophe%404.29.0","https://github.com/apostrophecms/apostrophe/security/advisories/GHSA-5f64-7vfc-rcx6","https://github.com/apostrophecms/apostrophe/security/advisories/GHSA-5f64-7vfc-rcx6"],"products":[],"source":"nvd","synced_at":"2026-10-26T11:33:08.859761529+00:00"},"epss":{"cve":"CVE-2026-45011","score":0.00211,"percentile":0.1129,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-5f64-7vfc-rcx6","url":"https://osv.dev/vulnerability/GHSA-5f64-7vfc-rcx6","summary":"Apostrophe has stored XSS via javascript: URL in Image Widget Link","modified":"2026-06-12T22:15:10.511551640Z","packages":[{"ecosystem":"npm","name":"apostrophe","purl":"pkg:npm/apostrophe","ranges":["4.29.0"],"fixed":[]}]}],"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).
