CVE-2025-48282: Majestic Support Auth Bypass Flaw

CVE-2025-48282 Overview

CVE-2025-48282 is a missing authorization vulnerability in the Majestic Support plugin for WordPress. The flaw affects all versions up to and including 1.1.0. The plugin fails to enforce proper access control checks on protected functionality, allowing unauthenticated attackers to interact with resources that should require authentication. The vulnerability is categorized under [CWE-862] (Missing Authorization) and is exploitable over the network without user interaction. Successful exploitation results in a limited integrity impact on affected WordPress installations that run the plugin.

Critical Impact
Unauthenticated network attackers can bypass access control checks in the Majestic Support plugin (versions through 1.1.0) and modify data that should be protected by authorization.

Affected Products

Majestic Support plugin for WordPress (majestic-support)
All versions from initial release through 1.1.0
WordPress sites with the Majestic Support plugin installed and active

Technical Details for CVE-2025-48282

Vulnerability Analysis

The Majestic Support plugin exposes functionality that lacks proper authorization enforcement. The plugin registers handlers or endpoints that perform sensitive operations without verifying whether the requesting user possesses the required capability or role. This class of flaw, tracked as [CWE-862], occurs when developers rely on obscurity, client-side controls, or nonce-only checks rather than server-side capability validation such as current_user_can().

An attacker sends crafted HTTP requests directly to the vulnerable plugin endpoint. Because no capability check is performed, the plugin processes the request and executes the underlying action. The attack requires no privileges and no user interaction, making it accessible to any remote actor who can reach the WordPress site.

The scope of impact is limited to integrity. Attackers can alter data handled by the plugin, but confidentiality and availability are not directly affected according to the CVSS vector. Support ticket plugins typically manage user submissions, agent replies, and ticket metadata, so unauthorized modification of these records represents the primary risk.

Root Cause

The root cause is the absence of server-side authorization checks on plugin actions. The Majestic Support codebase does not validate the requester's role or capability before executing protected functionality, an issue commonly referred to as broken access control.

Attack Vector

Exploitation occurs over the network against exposed WordPress endpoints. An attacker crafts an HTTP request targeting the vulnerable plugin action, for example through admin-ajax.php or a REST route registered by the plugin. Because the endpoint does not check whether the caller is authorized, the server processes the request and applies the requested change. Additional technical details are documented in the Patchstack Vulnerability Report.

Detection Methods for CVE-2025-48282

Indicators of Compromise

Unexpected modifications to Majestic Support ticket records, statuses, or agent assignments without corresponding authenticated sessions.
HTTP requests to admin-ajax.php or plugin-registered REST endpoints originating from unauthenticated sessions with plugin-specific action parameters.
New or altered support tickets created outside normal business workflows.

Detection Strategies

Audit WordPress access logs for anomalous POST requests targeting Majestic Support endpoints from clients without valid authentication cookies.
Compare installed plugin versions against 1.1.0 and flag any WordPress instance running an affected version.
Review database changes in tables owned by the Majestic Support plugin for edits that lack a corresponding authenticated user context.

Monitoring Recommendations

Enable verbose logging on WordPress and forward logs to a centralized SIEM for correlation and alerting on suspicious access patterns.
Deploy a web application firewall (WAF) rule set that alerts on requests to plugin endpoints missing expected authentication headers.
Monitor plugin file integrity and configuration changes on all WordPress hosts running Majestic Support.

How to Mitigate CVE-2025-48282

Immediate Actions Required

Identify all WordPress installations running the Majestic Support plugin and inventory their versions.
Upgrade Majestic Support to a version later than 1.1.0 once the vendor publishes a patched release.
If no fixed version is available, deactivate and remove the plugin from production sites until a patch is released.

Patch Information

At the time of publication, the vulnerability affects Majestic Support versions through 1.1.0. Administrators should consult the Patchstack Vulnerability Report and the plugin vendor's official channels for updated release information and apply any fixed version as soon as it becomes available.

Workarounds

Restrict access to WordPress administrative and AJAX endpoints using IP allowlists or reverse-proxy authentication where feasible.
Deploy WAF rules that block unauthenticated requests to Majestic Support plugin action names until an official fix is applied.
Reduce the plugin's attack surface by disabling unused features and removing the plugin entirely on sites that do not require its functionality.

bash

# Example: WP-CLI commands to inventory and remove the vulnerable plugin
wp plugin list --name=majestic-support --field=version
wp plugin deactivate majestic-support
wp plugin delete majestic-support
