Low risk16th percentile - higher than 16% of all known CVEs
Summary
The RPB Chessboard plugin for WordPress up to version 8.1.2 is vulnerable to Stored Cross-Site Scripting via Comment Content due to insufficient input sanitization and output escaping. Unauthenticated attackers can inject arbitrary scripts that execute when users access affected pages.
Risk Assessment
Attackers can inject malicious JavaScript into comments, leading to session theft, redirects, or site defacement for all visitors.
Recommendation
Immediately update the RPB Chessboard plugin to the latest version (above 8.1.2) and deploy a Web Application Firewall (WAF) to block XSS attacks.

The SigmaForms Pro – AI Generated Forms plugin for WordPress up to version 1.4.11 is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_submission_files function. Unauthenticated attackers can delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The malicious path traversal URL is submitted via form upload field and stored in the database, with deletion triggered when an administrator deletes the submission record from the admin panel.

The Booking for Appointments and Events Calendar – Amelia (Premium) plugin for WordPress versions 8.0 - 9.6.2 is vulnerable to privilege escalation due to insufficient validation of the 'type' parameter in the customer update endpoint. This allows customers to set their role to 'manager' and trigger creation of a WordPress user with the wpamelia-manager role when 'externalId' is set to 0. Unauthenticated attackers can escalate to administrator by first elevating to manager, then creating a provider entity linked to an administrator user ID and overwriting that administrator's password.

- CVE-2026-84480Critical
WWBN AVideo fails to validate password recovery token expiration in userRecoverPassSave.json.php, allowing attackers to use expired tokens to reset account passwords indefinitely. Attackers who obtain a recovery token can use it at any time to change the target account's password and gain full account access.
- CVE-2026-84479Critical
WWBN AVideo (current e01e41ecc and earlier) makes three login-time security controls depend solely on the client-supplied User-Agent header. The isAVideoEncoder()/isAVideoMobileApp() checks match HTTP_USER_AGENT against a hardcoded literal ("AVideoEncoder"/"AVideoMobileApp") with no IP check or shared secret. An attacker who submits valid credentials and sets User-Agent: AVideoEncoder bypasses two-factor authentication, skips brute-force captcha escalation, and avoids being recorded in the login/device audit history. No patch is available at the time of publication.
Original NVD description (English source)
The RPB Chessboard plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content in all versions up to, and including, 8.1.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. WordPress's save-time kses sanitization does not mitigate this issue because the crafted payload uses only kses-allowed tags and attributes (such as an <a> element with title and href), and the dangerous attribute-breaking HTML is synthesized entirely at render time by the plugin's own comment_text filter.
