{"cve":"CVE-2026-2352","nvd":{"published":"2026-03-21T00:16:25.873","modified":"2026-06-17T10:30:49.793","status":"Deferred","description":"The Autoptimize plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'ao_post_preload' meta value in all versions up to, and including, 3.1.14. This is due to insufficient input sanitization in the `ao_metabox_save()` function and missing output escaping when the value is rendered into a `<link>` tag in `autoptimizeImages.php`. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page, granted the \"Image optimization\" or \"Lazy-load images\" setting is enabled in the plugin configuration.","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:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["https://github.com/futtta/autoptimize/commit/60d1e487e536a97ae317784f8aeaf0d2e93cd717","https://plugins.trac.wordpress.org/browser/autoptimize/tags/3.1.14/classes/autoptimizeImages.php#L804","https://plugins.trac.wordpress.org/browser/autoptimize/tags/3.1.14/classes/autoptimizeImages.php#L938","https://plugins.trac.wordpress.org/browser/autoptimize/tags/3.1.14/classes/autoptimizeMetabox.php#L276","https://plugins.trac.wordpress.org/browser/autoptimize/trunk/classes/autoptimizeImages.php#L804"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-2352","score":0.0026,"percentile":0.17751,"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).
