This makes it possible for unauthenticated attackers to trash all published popups on the site with a single unauthenticated GET request. The attack is amplified by a second flaw in SGPopup::find(), which returns false for every normally published popup when the sg_popup_preview_id parameter is present, causing the trash branch to fire against every popup on the site simultaneously.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","score":9.1},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/popup-builder/tags/4.4.5/com/classes/Filters.php#L43","https://plugins.trac.wordpress.org/browser/popup-builder/tags/4.4.5/com/classes/Filters.php#L435","https://plugins.trac.wordpress.org/browser/popup-builder/tags/4.4.5/com/classes/popups/SGPopup.php#L1826","https://plugins.trac.wordpress.org/browser/popup-builder/tags/4.4.5/com/classes/popups/SGPopup.php#L1830","https://plugins.trac.wordpress.org/browser/popup-builder/tags/4.4.5/com/classes/popups/SGPopup.php#L257"],"products":[],"source":"nvd","synced_at":"2026-10-31T07:31:41.930515885+00:00"},"epss":null,"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).
