CVE-2025-31877 Overview
CVE-2025-31877 is a missing authorization vulnerability in the Magnigenie RestroPress plugin for WordPress. The flaw stems from incorrectly configured access control security levels [CWE-862]. All versions of RestroPress up to and including 3.2.8 are affected. An authenticated attacker with low privileges can abuse exposed functionality that lacks proper permission checks. The issue is tracked in the Patchstack vulnerability database and allows limited integrity impact over the network without user interaction.
Critical Impact
Authenticated users with low privileges can access or modify RestroPress plugin functionality that should be restricted to higher-privileged roles, impacting data integrity on affected WordPress sites.
Affected Products
- Magnigenie RestroPress plugin for WordPress
- RestroPress versions from n/a through <= 3.2.8
- WordPress sites with RestroPress installed and activated

Technical Details for CVE-2025-31877
Vulnerability Analysis
The vulnerability resides in RestroPress, a WordPress plugin for restaurant ordering and food delivery functionality. The plugin exposes one or more actions or endpoints without validating that the caller holds the required capability. An attacker who holds any authenticated session on the target site, including low-privileged roles such as subscriber or customer, can invoke the affected functionality. The result is a partial integrity impact on plugin data or configuration without affecting confidentiality or availability of the broader WordPress instance.
Root Cause
The root cause is a missing authorization check [CWE-862]. The plugin registers callable handlers but does not enforce current_user_can() capability checks or equivalent role validation before executing privileged logic. This represents an incorrectly configured access control security level where authentication is treated as sufficient authorization.
Attack Vector
Exploitation requires network access to the WordPress site and a valid authenticated account with low privileges. No user interaction is needed. The attacker sends a crafted HTTP request to the vulnerable RestroPress endpoint, bypassing the intended role-based access boundary. Public technical references do not include a proof-of-concept exploit, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

Stop Identity AttacksDetection Methods for CVE-2025-31877
Indicators of Compromise
- Unexpected modifications to RestroPress orders, menu items, settings, or customer records that cannot be attributed to administrative users.
- WordPress audit log entries showing low-privileged accounts triggering RestroPress AJAX actions or REST endpoints.
- HTTP POST requests from subscriber or customer sessions to RestroPress plugin handlers under /wp-admin/admin-ajax.php or /wp-json/.
Detection Strategies
- Inventory installed WordPress plugins and flag any RestroPress instance at version 3.2.8 or earlier.
- Review web server access logs for requests to RestroPress endpoints originating from non-administrative session cookies.
- Correlate authentication logs with plugin action calls to identify low-privileged users invoking restricted functionality.
Monitoring Recommendations
- Enable a WordPress activity logging plugin to capture plugin-level actions and user capability usage.
- Alert on HTTP 200 responses to RestroPress AJAX or REST calls when the authenticated user role is below shop manager or administrator.
- Monitor for anomalous changes to plugin options stored in the wp_options table.
How to Mitigate CVE-2025-31877
Immediate Actions Required
- Identify all WordPress sites running the RestroPress plugin and determine their installed version.
- Upgrade RestroPress to a release later than 3.2.8 that addresses the missing authorization check.
- Audit existing user accounts and remove unused low-privileged accounts that could be leveraged for exploitation.
- Review RestroPress data for unauthorized modifications made prior to patching.
Patch Information
Upgrade RestroPress to a version released after 3.2.8 that includes the fix referenced in the Patchstack advisory. Confirm the fixed version with the vendor before deployment. No vendor advisory URL beyond the Patchstack record is listed in the current CVE data.
Workarounds
- Deactivate the RestroPress plugin until a patched version can be installed if the site does not require ordering functionality.
- Deploy a web application firewall rule to block requests to vulnerable RestroPress endpoints from non-administrative sessions.
- Restrict registration of new low-privileged accounts and require administrator approval for customer accounts.
- Enforce strong authentication, including multi-factor authentication, for all WordPress accounts to reduce the pool of accounts an attacker can leverage.
