This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit works by embedding KSES-allowed markup such as abbr title attributes and HTML comments in a submitted comment so that the global strtr() substitution strips substrings from an inert tag, mutating it into an executable element such as an img onerror handler that runs in the WordPress origin for any visitor, including logged-in administrators.","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:N","score":7.2},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/trunk/iubenda-cookie-class/iubenda.class.php#L381","https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/trunk/iubenda-cookie-class/iubenda.class.php#L941","https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/trunk/iubenda_cookie_solution.php#L834","https://plugins.trac.wordpress.org/browser/iubenda-cookie-law-solution/trunk/iubenda_cookie_solution.php#L857","https://plugins.trac.wordpress.org/changeset/3675630/iubenda-cookie-law-solution/trunk/iubenda-cookie-class/iubenda.class.php"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-77263","score":0.00428,"percentile":0.37113,"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).
