This is due to insufficient input sanitization and output escaping combined with a custom unescaping routine that reintroduces dangerous characters. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/gutentools/tags/1.1.3/core/blocks/post-slider.php#L232","https://plugins.trac.wordpress.org/browser/gutentools/trunk/core/blocks/post-slider.php#L232","https://plugins.trac.wordpress.org/browser/gutentools/trunk/core/gutentools_block.php#L123","https://plugins.trac.wordpress.org/changeset/3476597/gutentools/trunk/core/blocks/post-slider.php","https://www.wordfence.com/threat-intel/vulnerabilities/id/b2683b4e-b993-4c84-b7cc-a2cb511b4097?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:30:49.762551342+00:00"},"epss":{"cve":"CVE-2026-1395","score":0.0024,"percentile":0.15142,"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).
