This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.","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://plugins.trac.wordpress.org/browser/optimole-wp/tags/4.2.1/inc/admin.php#L1012","https://plugins.trac.wordpress.org/browser/optimole-wp/tags/4.2.1/inc/manager.php#L459","https://plugins.trac.wordpress.org/browser/optimole-wp/tags/4.2.1/inc/manager.php#L542","https://plugins.trac.wordpress.org/browser/optimole-wp/trunk/inc/admin.php#L1012","https://plugins.trac.wordpress.org/browser/optimole-wp/trunk/inc/manager.php#L459"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-5226","score":0.00495,"percentile":0.425,"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).
