Low risk9th percentile - higher than 9% of all known CVEs
Summary
The RomanCart Ecommerce plugin for WordPress up to version 2.0.8 is vulnerable to Stored XSS via the 'blclass' attribute (and others) of the romancart_button shortcode. The romancart_button_shortcode() function lacks proper input sanitization and output escaping.
Risk Assessment
An authenticated attacker with contributor-level access or higher can inject arbitrary scripts that execute when users visit injected pages, leading to data theft or session hijacking.
Recommendation
Update the RomanCart Ecommerce plugin to the latest version. If unavailable, temporarily disable the plugin.

Qexo versions 4.0.0 through 4.2.0 expose /api/init_step/ without authentication, authorization, or a setup-completion guard.

IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 are vulnerable to privilege escalation. An authenticated attacker could craft a malicious request that bypasses additional authorization and input validation checks to execute malicious code and gain elevated privileges.
- CVE-2026-109575Critical
HAProxy Data Plane API versions 2.2.0 through 3.4.3 (and corresponding Enterprise Edition releases) have process-global authentication logic that improperly drops security controls across multiple transport types. When a TLS CA is configured and a numeric TLS port is specified, the application globally disables Basic authentication on its shared internal request handler, allowing unauthenticated attackers to reach affected HTTP or UNIX endpoints and completely bypass credentials to gain full API administrative access.
Original NVD description (English source)
The RomanCart Ecommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'blclass' attribute (and other attributes) of the romancart_button shortcode in versions up to, and including, 2.0.8. This is due to insufficient input sanitization and output escaping on user supplied attributes within the romancart_button_shortcode() function. 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.
