{"id":"CVE-2026-15345","state":"PUBLISHED","title":"ShortPixel Adaptive Images <= 3.11.5 - Missing Authorization to Authenticated (Subscriber+) Third-Party Plugin Option Modification via 'causer' Parameter","description":"The ShortPixel Adaptive Images – WebP, AVIF, CDN, Image Optimization plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.11.5. 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.","publishedAt":"2026-08-16T05:27:30.700Z","updatedAt":"2026-08-17T17:07:07.289Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["shortpixel ShortPixel Adaptive Images – WebP, AVIF, CDN, Image Optimization"],"affected":[{"vendor":"shortpixel","product":"ShortPixel Adaptive Images – WebP, AVIF, CDN, Image Optimization","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.11.5","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/c3efae8f-ca89-4d8c-a177-6793994b3ea0?source=cve","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/controllers/notice.class.php#L747","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#L87","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/changeset?reponame=&old=3625451%40shortpixel-adaptive-images&new=3625451%40shortpixel-adaptive-images"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15345.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15345","state":"PUBLISHED","datePublished":"2026-08-16T05:27:30.700Z","dateUpdated":"2026-08-17T17:07:07.289Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-09T20:25:55.728Z"},"containers":{"cna":{"title":"ShortPixel Adaptive Images <= 3.11.5 - Missing Authorization to Authenticated (Subscriber+) Third-Party Plugin Option Modification via 'causer' Parameter","descriptions":[{"lang":"en","value":"The ShortPixel Adaptive Images – WebP, AVIF, CDN, Image Optimization plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.11.5.
