CVE-2025-69345: BoldGrid Builder Auth Bypass Flaw

CVE-2025-69345 Overview

CVE-2025-69345 is a missing authorization vulnerability in the BoldGrid Post and Page Builder WordPress plugin. The flaw affects all versions up to and including 1.27.9. Incorrectly configured access control checks allow authenticated users with low privileges to invoke plugin functionality that should be restricted to higher-privileged roles. The vulnerability is classified under CWE-862: Missing Authorization and impacts integrity of WordPress sites running the affected plugin. Patchstack published the advisory tracking this issue.

Critical Impact
Authenticated attackers with minimal privileges can bypass access control and alter plugin-controlled content or settings on affected WordPress sites.

Affected Products

BoldGrid Post and Page Builder plugin for WordPress
All versions from initial release through 1.27.9

Technical Details for CVE-2025-69345

Vulnerability Analysis

The vulnerability stems from incorrectly configured access control security levels inside the Post and Page Builder plugin. One or more plugin actions fail to verify that the requesting user has sufficient capability before executing privileged operations. WordPress plugins typically guard sensitive actions with current_user_can() checks paired with nonce verification. When these checks are missing or scoped to an overly permissive role, authenticated low-privileged users can reach functionality intended for editors or administrators.

Exploitation requires only network access to the WordPress site and a valid authenticated session. No user interaction is required to trigger the affected endpoint. The impact is limited to integrity: an attacker cannot directly read confidential data or take the site offline through this flaw, but can modify plugin-managed content or state.

Root Cause

The root cause is a missing or insufficient authorization check on plugin handlers. The plugin exposes functionality through WordPress AJAX or REST endpoints without enforcing the correct capability for the action being performed. This is a classic [CWE-862] pattern where authentication is verified but authorization is not.

Attack Vector

An attacker authenticates to the WordPress instance with a low-privileged account such as Subscriber or Contributor. The attacker then sends a crafted request to the vulnerable plugin endpoint. Because the handler does not check the caller's role or capability, the request executes with the same effect as if a privileged user issued it. Refer to the Patchstack Vulnerability Report for additional technical context.

Detection Methods for CVE-2025-69345

Indicators of Compromise

Unexpected modifications to pages, posts, or builder templates made by low-privileged accounts
Requests from authenticated Subscriber or Contributor accounts to BoldGrid plugin AJAX or REST endpoints
New or modified plugin-managed records in wp_posts or wp_postmeta correlated with low-privileged user IDs

Detection Strategies

Inventory WordPress installations and identify sites running Post and Page Builder by BoldGrid at version 1.27.9 or earlier
Review web server access logs for admin-ajax.php and REST API calls referencing BoldGrid plugin actions originating from non-administrator accounts
Correlate WordPress audit logs with role assignments to detect privilege boundary violations

Monitoring Recommendations

Enable a WordPress activity log plugin to capture content changes and the originating user role
Forward web server and WordPress logs to a centralized SIEM for cross-account analysis
Alert on bursts of plugin-specific AJAX requests from accounts that lack editor or administrator capability

How to Mitigate CVE-2025-69345

Immediate Actions Required

Upgrade BoldGrid Post and Page Builder to a version later than 1.27.9 once released by the vendor
Audit existing WordPress user accounts and remove unused low-privileged accounts that could be leveraged for exploitation
Restrict new user registration on sites that do not require public sign-up

Patch Information

The Patchstack advisory tracks the affected range as versions up to and including 1.27.9. Apply the vendor fix when published by BoldGrid. Monitor the Patchstack Vulnerability Report for the fixed version reference.

Workarounds

Deactivate the Post and Page Builder plugin until a patched version is installed if the builder is not in active use
Apply virtual patching at a web application firewall to block unauthenticated and low-privileged calls to BoldGrid plugin endpoints
Enforce least privilege by reviewing role assignments and removing capabilities not required for daily operations

bash

# Identify installed plugin version using WP-CLI
wp plugin get post-and-page-builder --field=version

# Disable the plugin until a fixed version is available
wp plugin deactivate post-and-page-builder
