This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","score":4.8},"cwes":["CWE-79"],"references":["https://advisory.abay.sh/cve-2024-0621","https://plugins.trac.wordpress.org/changeset/3032350/","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3032350%40simple-share-buttons-adder&new=3032350%40simple-share-buttons-adder&sfp_email=&sfph_mail=","https://www.wordfence.com/threat-intel/vulnerabilities/id/93ab9f1a-26ce-466a-a5d3-d2046ec8f94d?source=cve","https://plugins.trac.wordpress.org/changeset/3032350/"],"products":["simplesharebuttons:simple_share_buttons_adder"],"source":"nvd","synced_at":"2026-10-19T21:45:59.823092188+00:00"},"epss":{"cve":"CVE-2024-0621","score":0.00491,"percentile":0.4224,"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).
