This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify configuration options of third-party plugins including ShortPixel Image Optimizer, Autoptimize, WP Rocket, Imagify, and LiteSpeed Cache, as well as the plugin's own API key and account binding. Exploitation requires the respective third-party plugins to be installed, as the impact against those plugins' settings is only reachable when those plugins are present.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/shortpixel-adaptive-images/tags/3.11.5/includes/actions/notice.actions.class.php#L16","https://plugins.trac.wordpress.org/browser/shortpixel-adaptive-images/tags/3.11.5/includes/actions/notice.actions.class.php#L566","https://plugins.trac.wordpress.org/browser/shortpixel-adaptive-images/tags/3.11.5/includes/actions/notice.actions.class.php#L614","https://plugins.trac.wordpress.org/browser/shortpixel-adaptive-images/tags/3.11.5/includes/actions/notice.actions.class.php#L87","https://plugins.trac.wordpress.org/browser/shortpixel-adaptive-images/tags/3.11.5/includes/controllers/notice.class.php#L747"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:10.689564601+00:00"},"epss":{"cve":"CVE-2026-15345","score":0.00428,"percentile":0.37119,"date":"2026-10-31"},"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).
