This is due to the Modula_Meta::add_metas() function being hooked to wp_head on every frontend request and looking up any post via get_post( $_GET['modula_gallery_id'] ) without verifying the gallery's post_status or the requester's capability to read it — the gallery-side input guard is bugged (empty('modula_gallery_id') tests a nonempty string literal instead of the GET parameter, so it is always false), the only object validation is a post_type === 'modula-gallery' check, and no is_user_logged_in()/current_user_can('read_post', $gallery_id) check is performed. This makes it possible for unauthenticated attackers to enumerate private modula-gallery posts and their member attachments and recover the image's title, description, dimensions, and original upload URL via Open Graph/Twitter meta tags emitted in the response, which then allows direct unauthenticated download of the original private image bytes.","state":0,"publishedAt":"2026-09-25T07:40:28.898+00:00","modifiedAt":"2026-09-25T13:00:14.389+00:00","affected":[{"ecosystem":"Vendor product","name":"Modula Image Gallery – Photo Grid & Video Gallery","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"wpchill\",\n                    \"product\": \"Modula Image Gallery – Photo Grid & Video Gallery\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"3.0.1\",\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:H/I:N/A:N","score":7.5,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/a369dff6-feca-47cf-8511-dc75c4ffdd29?source=cve","https://plugins.trac.wordpress.org/browser/modula-best-grid-gallery/tags/3.0.1/includes/public/meta/class-modula-meta.php#L142","https://plugins.trac.wordpress.org/browser/modula-best-grid-gallery/tags/3.0.1/includes/public/meta/class-modula-meta.php#L50","https://plugins.trac.wordpress.org/browser/modula-best-grid-gallery/tags/3.0.1/includes/public/meta/class-modula-meta.php#L26","https://plugins.trac.wordpress.org/browser/modula-best-grid-gallery/tags/3.0.1/includes/public/meta/social_meta.php#L8","https://plugins.trac.wordpress.org/changeset?reponame=&old=3697043%40modula-best-grid-gallery&new=3697043%40modula-best-grid-gallery"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-89406","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-89406","identifiers":["CVE-2026-89406"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
