CVE-2025-22770: Envo Multipurpose Auth Bypass Vulnerability

CVE-2025-22770 is an authorization bypass flaw in EnvoThemes Envo Multipurpose theme affecting versions through 1.1.6. Attackers can exploit misconfigured access controls to gain unauthorized access. This article covers technical details, affected versions, security impact, and mitigation strategies.

CVE-2025-22770 Overview

CVE-2025-22770 is a Missing Authorization vulnerability [CWE-862] in the EnvoThemes Envo Multipurpose WordPress theme. The flaw affects all versions of Envo Multipurpose up to and including 1.1.6. Attackers with low-privileged authenticated access can exploit incorrectly configured access control security levels to perform actions outside their permission scope. The vulnerability enables limited integrity and availability impact against affected WordPress sites running the theme.

Critical Impact
Authenticated users with minimal privileges can bypass access controls in the Envo Multipurpose theme, allowing unauthorized modifications that break the site's authorization model.

Affected Products

EnvoThemes Envo Multipurpose WordPress theme
All versions from initial release through 1.1.6
WordPress installations using the vulnerable theme

Technical Details for CVE-2025-22770

Vulnerability Analysis

The vulnerability stems from missing authorization checks within the Envo Multipurpose WordPress theme. Sensitive actions exposed by the theme do not verify whether the requesting user holds the correct capability or role. This design flaw falls under CWE-862 (Missing Authorization) and manifests as Broken Access Control. Authenticated users at any privilege level can invoke functions intended for higher-privileged roles. The impact is bounded to limited integrity and availability effects, with no direct confidentiality exposure.

Root Cause

The root cause is the absence of capability checks such as current_user_can() or equivalent role validation on theme-exposed endpoints and AJAX handlers. WordPress themes must explicitly validate authorization before executing state-changing operations. Envo Multipurpose relies on incorrectly configured access control levels rather than enforcing capability boundaries. This gap allows requests from low-privileged accounts to reach code paths intended for administrators.

Attack Vector

An attacker requires an authenticated session with low privileges on the target WordPress site. The attacker sends crafted HTTP requests to theme endpoints that lack proper authorization gates. Because the attack occurs over the network with low complexity and no user interaction, exploitation is straightforward once the attacker has any authenticated foothold. Successful exploitation lets the attacker perform actions restricted to higher-privileged roles, disrupting site integrity and availability.

See the Patchstack Vulnerability Report for additional technical details.

Detection Methods for CVE-2025-22770

Indicators of Compromise

Unexpected modifications to theme settings, options, or content by non-administrator accounts
HTTP POST requests from low-privileged accounts to Envo Multipurpose theme endpoints or admin-ajax.php actions registered by the theme
WordPress audit log entries showing privilege-inconsistent actions performed by subscriber or contributor accounts

Detection Strategies

Monitor WordPress access logs for authenticated requests targeting theme-specific AJAX actions or admin endpoints
Correlate user role information with the sensitivity of actions performed through Envo Multipurpose handlers
Deploy WordPress security plugins that log capability checks and flag calls to theme functions from unexpected roles

Monitoring Recommendations

Enable WordPress activity logging with role-based filtering to identify anomalous administrative actions
Track the installed version of Envo Multipurpose across managed WordPress sites and alert on versions at or below 1.1.6
Review web application firewall (WAF) telemetry for repeated requests to theme endpoints from newly registered accounts

How to Mitigate CVE-2025-22770

Immediate Actions Required

Update the Envo Multipurpose theme to a version above 1.1.6 once a patched release is available from EnvoThemes
Restrict user registration and audit existing low-privileged accounts on affected WordPress sites
Apply virtual patching rules through a WordPress-aware WAF to block unauthorized access to theme endpoints

Patch Information

Refer to the Patchstack Vulnerability Report for current patch status and vendor guidance. Administrators should monitor the EnvoThemes theme changelog and apply updates that address the missing authorization checks.

Workarounds

Disable the Envo Multipurpose theme and switch to an alternative WordPress theme until a patched version is released
Remove or disable user registration on the affected site to prevent attackers from obtaining the required authenticated foothold
Deploy a WordPress security plugin that enforces capability checks on theme AJAX handlers and admin actions

bash

# Configuration example: disable open registration in wp-config.php
# via WP-CLI
wp option update users_can_register 0

# List installed themes and versions to identify vulnerable sites
wp theme list --fields=name,status,version | grep envo-multipurpose
