CVE-2025-69403: 
WordPress vulnerability analysis and mitigation

CVE-2025-69403 is an Unrestricted File Upload vulnerability (CWE-434) in the Bravis Addons WordPress plugin by Bravis-Themes. It allows low-privileged authenticated attackers to upload files of dangerous types, potentially enabling remote code execution. All versions up to and including 1.3.0 are affected. The vulnerability was published on February 20, 2026, and carries a CVSS v3.1 base score of 9.9 (Critical) (Feedly, Wordfence).

The vulnerability is classified as CWE-434 (Unrestricted Upload of File with Dangerous Type), meaning the plugin fails to properly validate or restrict the types of files that authenticated users can upload. An attacker with low-level privileges (e.g., a subscriber or contributor account) can upload a malicious file — such as a PHP web shell — to the server without adequate type or content checks. The attack vector is network-based, requires no user interaction, and has a changed scope, indicating that a successful exploit can impact resources beyond the vulnerable component itself (Feedly).

Successful exploitation grants an attacker the ability to upload and execute arbitrary code on the web server, resulting in full compromise of confidentiality, integrity, and availability. Because the CVSS scope is marked as "Changed," the impact extends beyond the WordPress installation itself — potentially affecting the underlying server, hosted databases, and other co-located applications. This could enable lateral movement within a hosting environment, data exfiltration, defacement, or deployment of malware (Feedly).

The vulnerability requires only low-level authentication (e.g., a registered WordPress user), making it relatively easy to exploit on sites with open registration. The EPSS score is 0.018% (0.000180), suggesting low observed exploitation probability at this time, and there is no current evidence of active in-the-wild exploitation or CISA KEV catalog listing. No public proof-of-concept exploit code has been identified in the available sources (Feedly, Wordfence).

1. Reconnaissance: Identify WordPress sites running the Bravis Addons plugin version ≤ 1.3.0 using tools like WPScan, Shodan, or Google dorks (e.g., inurl:wp-content/plugins/bravis-addons).
2. Obtain low-privileged access: Register as a subscriber or use any existing low-privileged account on the target WordPress site.
3. Locate the vulnerable upload endpoint: Identify the plugin's file upload functionality exposed through the WordPress admin interface or a front-end form provided by the Bravis Addons plugin.
4. Craft a malicious payload: Prepare a PHP web shell (e.g., <?php system($_GET['cmd']); ?>) saved with a .php extension.
5. Upload the malicious file: Submit the PHP file through the vulnerable upload endpoint, bypassing the plugin's insufficient file type validation.
6. Execute the payload: Navigate to the uploaded file's URL (typically within wp-content/uploads/ or a plugin-specific directory) and execute arbitrary commands via the web shell to achieve remote code execution (Feedly).

• File System: Unexpected .php files or files with double extensions (e.g., .php.jpg) in wp-content/uploads/ or plugin directories; newly created web shell files with obfuscated content.
• Logs: Web server access logs showing POST requests to Bravis Addons upload endpoints followed by GET requests to newly created files in upload directories; requests containing cmd=, exec=, or similar shell command parameters.
• Network: Outbound connections from the web server process to unknown external IPs, particularly on non-standard ports; reverse shell traffic originating from the web server.
• Process: Unusual child processes spawned by the web server (e.g., php, bash, curl, wget) executing system commands.

Users should update the Bravis Addons plugin to a version beyond 1.3.0 as soon as a patched release is available from the plugin vendor or the WordPress plugin repository. In the interim, site administrators should disable the plugin entirely if it is not critical to site operation. Additionally, implementing a Web Application Firewall (WAF) rule to block uploads of executable file types (e.g., .php, .phtml, .phar) and restricting user registration on the site can reduce exposure (Wordfence, Feedly).

Wordfence included CVE-2025-69403 in its weekly WordPress vulnerability report for the period of February 9–15, 2026, highlighting it as a notable high-severity issue for WordPress site administrators (Wordfence). No additional significant vendor statements or notable researcher commentary have been identified at this time.
