This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. Exploitation requires that a submitted comment containing the shortcode payload in an href or src attribute is approved through the site's normal comment moderation workflow; once approved, the shortcode is executed automatically via WP-Cron without any further attacker interaction.","state":0,"publishedAt":"2026-10-16T04:26:58.157+00:00","modifiedAt":"2026-10-16T15:09:40.737+00:00","affected":[{"ecosystem":"Vendor product","name":"Broken Link Checker","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"wpmudev\",\n                    \"product\": \"Broken Link Checker\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"2.4.14.1\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","score":6.5,"severity":"MEDIUM"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/04cc4b99-8c27-4f95-b860-608c01af843b?source=cve","https://plugins.trac.wordpress.org/browser/broken-link-checker/tags/2.4.14.1/legacy/modules/parsers/html_link.php#L72","https://plugins.trac.wordpress.org/browser/broken-link-checker/tags/2.4.14.1/legacy/modules/parsers/image.php#L66","https://plugins.trac.wordpress.org/browser/broken-link-checker/tags/2.4.14.1/legacy/modules/containers/comment.php#L229","https://plugins.trac.wordpress.org/browser/broken-link-checker/tags/2.4.14.1/legacy/includes/containers.php#L298","https://plugins.trac.wordpress.org/changeset?reponame=&old=3740705%40broken-link-checker&new=3740705%40broken-link-checker"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-96562","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-96562","identifiers":["CVE-2026-96562"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
