This is due to the use of `strpos()` for substring-based hostname validation instead of strict host comparison in the `ajax_upload_image()` function. 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:C/C:L/I:N/A:N","score":5.0},"cwes":["CWE-918"],"references":["https://plugins.trac.wordpress.org/browser/responsive-lightbox/tags/2.7.0/includes/class-remote-library.php#L329","https://plugins.trac.wordpress.org/browser/responsive-lightbox/tags/2.7.0/includes/class-remote-library.php#L344","https://plugins.trac.wordpress.org/browser/responsive-lightbox/trunk/includes/class-remote-library.php#L329","https://plugins.trac.wordpress.org/changeset/3464566?contextall=1","https://www.wordfence.com/threat-intel/vulnerabilities/id/44276b28-9509-4f59-936c-fff2ae404076?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:24:17.937441719+00:00"},"epss":{"cve":"CVE-2026-2479","score":0.00266,"percentile":0.18608,"date":"2026-11-01"},"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).
