Overview
CVE-2025-12630 is a medium-severity vulnerability affecting the Upload.am WordPress plugin versions prior to 1.0.1. This vulnerability allows unauthorized users, including those with contributor-level access, to view sensitive site options due to a missing capability check in the plugin’s AJAX request handler. This can lead to the disclosure of configuration details that could be exploited for further malicious activities.
Technical Details
The vulnerability resides in the AJAX request handler within the Upload.am plugin. Specifically, the handler lacks proper authorization checks to verify if the user making the request has the necessary capabilities to access or modify site options. As a result, even users with limited privileges, such as contributors, can trigger the AJAX request and retrieve a list of site options, potentially exposing sensitive information like API keys, database credentials (if improperly stored), and other configuration settings.
CVSS Analysis
The vulnerability has been assigned a CVSS score of 4.9 (Medium).
- CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N
- Attack Vector (AV): Network (N)
- Attack Complexity (AC): Low (L)
- Privileges Required (PR): High (H)
- User Interaction (UI): None (N)
- Scope (S): Unchanged (U)
- Confidentiality (C): High (H)
- Integrity (I): None (N)
- Availability (A): None (N)
While the CVSS score is moderate, the potential impact of exposing sensitive site options warrants immediate attention.
Possible Impact
Successful exploitation of this vulnerability could lead to:
- Exposure of sensitive site configuration data: This includes API keys, database connection strings (if incorrectly stored in options), and other internal settings.
- Privilege escalation: An attacker could leverage the disclosed information to gain higher-level access to the WordPress site.
- Data breach: Exposed database credentials could lead to a full database compromise.
- Site defacement or takeover: An attacker with access to sensitive configuration data could potentially deface or completely take over the WordPress site.
Mitigation/Patch Steps
The primary mitigation step is to immediately update the Upload.am WordPress plugin to version 1.0.1 or later. This version contains the necessary fix to address the missing capability check and prevent unauthorized access to site options.
- Log in to your WordPress admin dashboard.
- Navigate to “Plugins” -> “Installed Plugins”.
- Locate the “Upload.am” plugin.
- If an update is available, click the “Update Now” link.
- If no update is available, ensure you are running at least version 1.0.1. If not, consider removing the plugin until an updated version is available.
Additionally, as a general security best practice, review your WordPress site options and ensure that sensitive information is not stored directly within the options table. Consider using more secure methods for storing credentials and other sensitive data.
