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.
Unauthenticated attackers can exploit SQL injection in Support Board v3.7.7's AJAX endpoint to fully compromise the application database through the calls[0][message_ids][] parameter, enabling complete data exfiltration and manipulation. The vulnerability requires only low privileges and network access, with no user interaction needed, making it trivially exploitable in multi-tenant environments. A patch is available and should be applied immediately given the HIGH severity rating and complete database access impact.
A Reflected Cross-Site Scripting (XSS) vulnerability exists in Support Board v3.7.7 that allows unauthenticated attackers to inject malicious JavaScript code via the 'search' parameter in the '/supportboard/include/articles.php' endpoint. Successful exploitation enables attackers to steal session cookies, perform unauthorized actions on behalf of victims, or harvest sensitive user data through victim browsers. A vendor patch is available, and the vulnerability has been officially reported by INCIBE, indicating moderate real-world attention.
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.
The Support Board WordPress plugin before 3.3.4 does not escape multiple POST parameters (such as status_code, department, user_id, conversation_id, conversation_status_code, and recipient_id) before. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
In the Schiocco "Support Board - Chat And Help Desk" plugin 1.2.3 for WordPress, a Stored XSS vulnerability has been discovered in file upload areas in the Chat and Help Desk sections via the msg. Rated medium severity (CVSS 5.4), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
