CVE-2025-26955: Industrial Lite Auth Bypass Vulnerability

CVE-2025-26955 Overview

CVE-2025-26955 is a Missing Authorization vulnerability [CWE-862] in the vowelweb Industrial Lite WordPress theme. The flaw affects all versions of industrial-lite from initial release through version 1.0.8. The theme fails to enforce proper access control checks, allowing authenticated users with low privileges to reach functionality that should require elevated permissions.

The issue stems from incorrectly configured access control security levels within the theme. An attacker with basic authenticated access can exploit the missing authorization check over the network without user interaction. Successful exploitation impacts availability of the affected WordPress site.

Critical Impact

Authenticated attackers can bypass access control checks to reach functionality restricted to higher-privileged users, degrading site availability.

Affected Products

• vowelweb Industrial Lite WordPress theme (industrial-lite)
• All versions from initial release through 1.0.8
• WordPress installations using the vulnerable theme

Technical Details for CVE-2025-26955

Vulnerability Analysis

The vulnerability is a Broken Access Control issue classified under CWE-862: Missing Authorization. The Industrial Lite theme exposes one or more endpoints or actions that do not verify the caller's role or capability before executing privileged operations.

WordPress themes commonly register AJAX handlers, admin-post actions, or custom endpoints. When these handlers omit current_user_can() capability checks or nonce validation, any authenticated user can invoke them. In Industrial Lite versions up to 1.0.8, this omission allows subscriber-level accounts to trigger actions intended for administrators.

Exploitation requires network access and low-privilege authentication. No user interaction is needed, and attack complexity is low. The impact is limited to availability degradation, with no direct confidentiality or integrity loss reported.

Root Cause

The root cause is missing authorization enforcement in theme code paths. The theme registers callable actions without validating whether the requesting user holds the required WordPress capability. This constitutes an incorrectly configured access control security level, where security decisions rely on client-side or implicit trust rather than server-side capability checks.

Attack Vector

An attacker first obtains any authenticated account on the target WordPress site. This can be a subscriber account created through open registration. The attacker then sends crafted HTTP requests to the vulnerable theme endpoints. Because the server does not verify authorization, the requests execute successfully and affect site availability.

No verified public exploit code is available. Refer to the Patchstack Vulnerability Report for further technical context.

Detection Methods for CVE-2025-26955

Indicators of Compromise

• Unexpected HTTP POST requests to admin-ajax.php or admin-post.php from low-privilege user sessions targeting Industrial Lite theme actions
• WordPress activity logs showing subscriber or contributor accounts triggering theme configuration changes
• Sudden availability disruptions on WordPress sites running the industrial-lite theme at version 1.0.8 or earlier

Detection Strategies

• Inventory WordPress installations to identify sites running the Industrial Lite theme and confirm installed versions
• Review web server access logs for authenticated requests to theme-registered endpoints originating from non-administrative accounts
• Correlate WordPress audit logs with HTTP traffic to identify capability-check bypass patterns

Monitoring Recommendations

• Enable WordPress activity logging plugins to capture privileged actions and the invoking user role
• Monitor rate and origin of requests to wp-admin/admin-ajax.php for anomalous patterns from low-privilege users
• Alert on modifications to theme options or site configuration performed by non-administrator accounts

How to Mitigate CVE-2025-26955

Immediate Actions Required

• Identify all WordPress sites running the industrial-lite theme at version 1.0.8 or earlier
• Disable open user registration or restrict the default role assigned to new accounts until a patch is applied
• Audit existing low-privilege accounts for unauthorized changes to site configuration

Patch Information

At the time of publication, no fixed version is listed in the referenced advisory. Monitor the Patchstack advisory and the WordPress theme repository for updates from the vendor. If no patch is available, consider replacing the theme with a maintained alternative.

Workarounds

• Deactivate and remove the Industrial Lite theme until a vendor-supplied fix is released
• Deploy a web application firewall rule to block requests to vulnerable theme endpoints from non-administrator sessions
• Restrict WordPress user registration and enforce least-privilege role assignments for all accounts

# Example: disable open registration via wp-cli until a patch is available
wp option update users_can_register 0
wp option update default_role subscriber

# List sites using the vulnerable theme across a multisite install
wp site list --field=url | xargs -I {} wp --url={} theme list --status=active --format=csv
