Summary
nest-admin before 1.0.1 contains an authentication bypass that lets unauthenticated attackers forge administrator tokens using a hardcoded JWT_SECRET committed in .env.production. Attackers can sign tokens with the known secret trusted by JwtStrategy and RbacGuard, impersonating any user ID or claiming the admin role.
Risk Assessment
This grants full administrative access without authentication, potentially leading to takeover of the application and its data. The risk is critical because the secret is publicly known and no credentials are required.
Recommendation
Update nest-admin to 1.0.1 or later and immediately generate a new unique JWT_SECRET, removing the hardcoded secret from the repository and deployment files. Review logs for suspicious tokens and administrative actions.

The s2Member plugin for WordPress in versions up to and including 260927 is vulnerable to Remote Code Execution via the 'item_name' parameter. Insufficient sanitization in strip_php_tags_deep() only strips literal '<?' sequences, and a post-interpolation placeholder cleanup reassembles a valid '<?php' opener after the attacker-controlled value has already been embedded in the email template.
- CVE-2026-97718Critical

The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the _getObjAttr function in all versions up to, and including, 3.5.54. This makes it possible for unauthenticated attackers to 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). This requires the PDF Generator add-on to be active and a Contact Form 7 form to be configured for PDF generation.
