Support Board

Unauthenticated privilege escalation in the Support Board WordPress plugin (versions prior to 3.8.9) allows remote attackers with no credentials to elevate privileges on affected WordPress sites. The flaw was reported by Patchstack and is tied to CWE-266 (Incorrect Privilege Assignment), with a critical CVSS 3.1 base score of 9.8 reflecting network-reachable, low-complexity exploitation. No public exploit identified at time of analysis, but the unauthenticated nature and plugin's customer-support role make this a high-priority patch for any WordPress site running it.
The Support Board plugin for WordPress is vulnerable to unauthorized access/modification/deletion of data due to use of hardcoded default secrets in the sb_encryption() function in all versions up to, and including, 3.8.0. This makes it possible for unauthenticated attackers to bypass authorization and execute arbitrary AJAX actions defined in the sb_ajax_execute() function. An attacker can use this vulnerability to exploit CVE-2025-4828 and various other functions unauthenticated.
The Support Board plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the sb_file_delete function in all versions up to, and including, 3.8.0. This makes it possible for 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). An attacker can leverage CVE-2025-4855 vulnerability to exploit this vulnerability unauthenticated.
The Support Board WordPress plugin before 3.3.5 allows Authenticated (Agent+) users to perform Cross-Site Scripting attacks by placing a payload in the notes field, when an administrator or any. Rated medium severity (CVSS 5.4), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available and no vendor patch available.
