DescriptionCVE.org

The ShopLentor - WooCommerce Builder for Elementor & Gutenberg plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'blockUniqId' block attribute in multiple Product Gride blocks in versions up to, and including, 3.3.8 due to insufficient input sanitization and output escaping. 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.

AnalysisAI

Stored Cross-Site Scripting in ShopLentor (WordPress plugin, versions ≤ 3.3.8) allows authenticated contributors to permanently embed malicious JavaScript into WordPress pages via the 'blockUniqId' attribute of Product Grid blocks. Any user who subsequently visits an injected page triggers script execution in their browser, enabling session hijacking, credential theft, or unauthorized actions on behalf of the victim. EPSS is negligible at 0.03% (9th percentile), no CISA KEV listing exists, and no public exploit has been identified at time of analysis.

Technical ContextAI

CWE-79 (Improper Neutralization of Input During Web Page Generation - Stored XSS) describes the root cause: user-supplied input is stored without adequate sanitization and later rendered without proper output escaping. The specific sink is the 'blockUniqId' attribute processed by multiple Product Grid blocks in the ShopLentor plugin (woolentor-addons), a WooCommerce page-builder plugin compatible with both Elementor and Gutenberg. The CVSS scope indicator S:C (Changed Scope) confirms that the injected script executes in a different security context than the one where it was introduced - specifically, the victim's browser session rather than the contributor's own session. The WordPress plugin is identified in ENISA EUVD-2026-32052 as 'ShopLentor - All-in-One WooCommerce Growth & Store Enhancement Plugin' covering all versions from 0 through 3.3.8 inclusive.

RemediationAI

An upstream fix has been committed to the plugin repository as WordPress Trac changeset 3521229 (https://plugins.trac.wordpress.org/changeset/3521229/woolentor-addons); however, the exact released patched version number is not independently confirmed from the available input data - site administrators should update to the latest available ShopLentor version above 3.3.8 via the WordPress dashboard or WP-CLI and verify the installed version exceeds 3.3.8. As a compensating control while patching is pending, restrict contributor-level role assignment to only fully trusted users, since the attack requires at minimum contributor access to create or edit block-based content. Auditing existing pages for unexpected script content in Product Grid block attributes is advisable on sites with multiple contributors. Note that restricting contributor access may impair editorial workflows; weigh this trade-off against exposure window.
