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. Exploitation requires the targeted site to have a publicly accessible page containing an [mla_gallery] shortcode configured with a pagination output mode and an mla_link_href template that reflects a {+request:...+} token, along with enough attachments to trigger pagination.","state":0,"publishedAt":"2026-10-29T09:25:33.216+00:00","modifiedAt":"2026-10-29T10:45:41.805+00:00","affected":[{"ecosystem":"Vendor product","name":"Media Library Assistant","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"dglingren\",\n                    \"product\": \"Media Library Assistant\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"3.42\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N","score":4.7,"severity":"MEDIUM"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/357d9d96-afb1-4b62-90cf-8d38a4cede0e?source=cve","https://plugins.trac.wordpress.org/browser/media-library-assistant/tags/3.42/includes/class-mla-shortcode-support.php#L2585","https://plugins.trac.wordpress.org/browser/media-library-assistant/tags/3.42/includes/class-mla-shortcode-support.php#L2482","https://plugins.trac.wordpress.org/browser/media-library-assistant/tags/3.42/includes/class-mla-data.php#L1548","http://plugins.trac.wordpress.org/changeset/3760471","https://plugins.trac.wordpress.org/browser/media-library-assistant/tags/3.43/includes/class-mla-shortcode-support.php"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-103875","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-103875","identifiers":["CVE-2026-103875"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
