CVE-2024-5617
MediumCVSS 4.8Summary
The account lock feature fails to correctly enforce account lockouts on the primary user store when users with identical usernames exist in both primary and secondary user stores. The lock condition is only applied to the secondary user store account, allowing continued authentication attempts against the primary user store account. This flaw enables brute force attacks.
Risk Assessment
An attacker could systematically guess passwords for the primary user store account, potentially gaining unauthorized access to sensitive information or accounts.
Recommendation
Apply the vendor patch that restores proper account lockout enforcement across both user stores and consider additional login attempt throttling mechanisms.

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-2026-102435Critical
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.

kaniko before 1.25.20 can send a Microsoft Entra ID (Azure AD) access token for Azure Resource Manager to an attacker-controlled registry host.

- CVE-2026-94290Critical
The SUSE Rancher Fleet controller did not sufficiently restrict which kubeconfig secrets a Fleet Cluster object was allowed to reference. As a result, an ordinary user could define a cluster in a namespace they control and associate it with administrative credentials for the management cluster, causing the controller to manage the management cluster on that user's behalf with elevated privileges. This affects Fleet 0.16.0–0.16.3, 0.15.0–0.15.8, 0.14.0–0.14.12, 0.13.0–0.13.17 and possibly older versions.
Original NVD description (English source)
The account lock feature fails to correctly enforce account lockouts on the primary user store when users with identical usernames exist in both primary and secondary user stores. This occurs because the lock condition is only applied to the secondary user store account in such scenarios, allowing continued authentication attempts against the primary user store account. This functional flaw enables brute force attacks. By systematically attempting different passwords against the primary user store account, an attacker can potentially gain unauthorized access to sensitive information or accounts, as the intended account lockout mechanism does not prevent repeated login attempts.
