CVE-2025-64248: Request a Quote Auth Bypass Vulnerability

CVE-2025-64248 Overview

CVE-2025-64248 is a missing authorization vulnerability in the emarket-design Request a Quote plugin for WordPress. The flaw affects all versions of request-a-quote up to and including 2.5.3. The vulnerability stems from incorrectly configured access control security levels, allowing authenticated users with low privileges to reach functionality that should be restricted. The issue is categorized under [CWE-862] Missing Authorization.

Critical Impact
An authenticated attacker with low privileges can access plugin functionality outside their authorization scope, resulting in limited integrity impact on affected WordPress sites.

Affected Products

Technical Details for CVE-2025-64248

Vulnerability Analysis

The Request a Quote plugin exposes one or more actions that do not properly enforce capability checks. An authenticated user with minimal privileges, such as a subscriber, can invoke these actions and perform operations reserved for higher-privileged roles. The impact is limited to integrity because the flaw does not expose confidential data or degrade availability. The attack requires network access to the WordPress site and no user interaction beyond the attacker's own request.

Root Cause

The root cause is the absence of proper authorization checks on plugin endpoints. WordPress plugins typically enforce access control through current_user_can() capability checks and nonce validation on AJAX handlers or admin-post actions. When these checks are missing or misconfigured, any authenticated session can trigger the underlying handler. The Patchstack report classifies this as a broken access control condition in request-a-quote versions up to 2.5.3.

Attack Vector

Exploitation proceeds over the network against a WordPress site running a vulnerable plugin version. An attacker first obtains any authenticated account, including a self-registered subscriber where open registration is enabled. The attacker then issues crafted HTTP requests to plugin endpoints that lack authorization enforcement. Successful requests allow the attacker to modify plugin state or trigger actions intended for administrators.

No public proof-of-concept exploit code is available at the time of publication. For technical specifics, refer to the Patchstack Vulnerability Report.

Detection Methods for CVE-2025-64248

Indicators of Compromise

Unexpected changes to quote request records, plugin settings, or associated post types created by low-privileged accounts
Requests to admin-ajax.php or plugin-specific endpoints originating from subscriber-level user sessions
New or modified plugin data timestamps that do not correlate with administrator activity

Detection Strategies

Inventory WordPress installations and identify sites running request-a-quote version 2.5.3 or earlier
Review web server access logs for POST requests to plugin endpoints made by non-administrative user IDs
Correlate WordPress audit logs with authentication events to identify low-privileged users performing privileged actions

Monitoring Recommendations

Enable a WordPress activity log plugin to record capability-level actions and role changes
Alert on any modification to plugin configuration or quote records performed by subscriber or contributor accounts
Monitor for spikes in authenticated AJAX traffic to plugin handlers, which may indicate enumeration or abuse

How to Mitigate CVE-2025-64248

Immediate Actions Required

Update the Request a Quote plugin to a version newer than 2.5.3 once the vendor releases a patched release
Disable and remove the plugin if a fixed version is not yet available and the functionality is not essential
Audit WordPress user accounts and disable open self-registration where it is not required

Patch Information

At the time of publication, the enriched CVE data does not list a fixed version. Administrators should consult the Patchstack Vulnerability Report and the vendor's plugin page for release notes covering versions after 2.5.3.

Workarounds

Restrict access to /wp-admin/admin-ajax.php plugin actions using a web application firewall rule scoped to authenticated user roles
Enforce least privilege on WordPress accounts and remove unused subscriber or contributor accounts
Deploy a virtual patching solution such as Patchstack or a WAF ruleset that blocks unauthorized access to the vulnerable plugin endpoints

bash

# Example: disable the plugin via WP-CLI until a patched version is available
wp plugin deactivate request-a-quote
wp plugin status request-a-quote
