Impact

This is a genuine but low-severity information disclosure issue, correctly scored at CVSS 5.3. The vector (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) reflects reality: an unauthenticated network attacker can, with no user interaction and low complexity, retrieve the description of products that a site owner deliberately protected with a WordPress post password. Impact is confidentiality-only and limited (C:L) - no data modification, no availability effect, and only the product description leaks rather than credentials or full site data. No EPSS score, no CISA KEV listing, and no public POC are present in the provided intelligence, so there is no evidence of active or automated exploitation. The signals are internally consistent (no CVSS-vs-description conflict here). Net priority: patch during routine maintenance. The main real-world consequence is defeating an access-control decision a merchant intended (e.g., previewing hidden/embargoed product info), not a system compromise.

This Month Plan within 30 days. Why: MEDIUM severity (CVSS 4.0-6.9).

AnalysisAIv1 – Sep 23, 2026

Unauthenticated information disclosure in the WPC Smart Compare for WooCommerce plugin before 6.6.1 allows remote attackers to read the descriptions of password-protected WooCommerce products, because the plugin's comparison handler returns product content without applying WordPress's post-password protection. The issue is rated CVSS 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N), so it is limited to confidentiality with low impact and no integrity or availability effect, and no public exploit has been identified at time of analysis. A vendor patch is available in 6.6.1 and the exposure is confined to content that site owners intended to keep behind a password.

RemediationAI

Vendor-released patch: upgrade the WPC Smart Compare for WooCommerce plugin to 6.6.1 or later, as confirmed by the patch data and the WPScan advisory at https://wpscan.com/vulnerability/ff8a599b-e74f-485e-baf8-8d162633b2ea/. If an immediate upgrade is not possible, deactivate the plugin or remove the comparison shortcode/block and its associated AJAX handler so the vulnerable endpoint is no longer reachable; the trade-off is that product comparison functionality is lost for all visitors. A WAF rule that blocks unauthenticated requests to the plugin's comparison AJAX action on admin-ajax.php reduces exposure but requires maintenance against action-name changes and does not correct the underlying code. Because WordPress post-password protection is bypassed while an unpatched version is active, site owners should not treat password-protected product descriptions as confidential until the plugin is upgraded.

Technical ContextAI · show details

WordPress implements per-post content protection through the post_password field and the post_password_required() check, which normally causes get_the_content() and related APIs to return only the password form instead of the protected body. WooCommerce products are a custom post type and inherit that same protection, so any plugin rendering product data is expected to honour the password check. WPC Smart Compare for WooCommerce instead retrieves and returns product descriptions directly from its comparison handler without that gate, exposing the protected text to any visitor - this is a classic CWE-200 exposure of sensitive information to an unauthorized actor. The supplied intelligence identifies the vulnerable range via EUVD-2026-85055 as WPC Smart Compare for WooCommerce 0 <6.6.1; no CPE strings were included, and the network-based, unauthenticated CVSS 3.1 vector confirms the flaw is reachable over HTTP with no privileges, no user interaction, and only a low confidentiality impact.
