This is due to insufficient validation of user-supplied URLs when determining image dimensions for gallery items. This makes it possible for authenticated attackers, with Author-level access and above, to make web requests to arbitrary locations originating from the web application which can be used to query and modify information from internal services.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4},"cwes":["CWE-918"],"references":["https://plugins.trac.wordpress.org/browser/responsive-lightbox/tags/2.5.3/includes/class-fast-image.php#L25","https://plugins.trac.wordpress.org/browser/responsive-lightbox/tags/2.5.3/includes/class-frontend.php#L1531","https://plugins.trac.wordpress.org/browser/responsive-lightbox/tags/2.5.3/includes/class-galleries.php#L3648","https://plugins.trac.wordpress.org/browser/responsive-lightbox/tags/2.5.3/includes/functions.php#L108","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3397940%40responsive-lightbox%2Ftrunk&old=3358021%40responsive-lightbox%2Ftrunk&sfp_email=&sfph_mail="],"products":[],"source":"nvd","synced_at":"2026-10-19T22:16:02.354564667+00:00"},"epss":{"cve":"CVE-2025-12359","score":0.00255,"percentile":0.16962,"date":"2026-10-25"},"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).
