CVE-2026-32370: Influencer Theme Auth Bypass Vulnerability

CVE-2026-32370 Overview

CVE-2026-32370 is a Missing Authorization vulnerability affecting the Influencer WordPress theme by raratheme. This broken access control flaw allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthorized actions within WordPress installations running the vulnerable theme. The vulnerability stems from missing authorization checks (CWE-862), which could allow unauthenticated attackers to perform actions that should be restricted to authorized users only.

Critical Impact

Unauthenticated attackers can exploit missing authorization controls in the Influencer theme to bypass access restrictions and perform unauthorized modifications to WordPress site content or settings.

Affected Products

• raratheme Influencer WordPress theme version 1.1.7 and earlier
• WordPress installations using vulnerable Influencer theme versions

Technical Details for CVE-2026-32370

Vulnerability Analysis

This vulnerability represents a Broken Access Control flaw where the Influencer WordPress theme fails to properly implement authorization checks on certain functionality. Without proper authorization validation, the theme accepts and processes requests from users regardless of their permission level. This type of vulnerability allows attackers to interact with functionality that should be protected, potentially modifying site content, settings, or other theme-controlled elements without authentication.

The network-accessible nature of this vulnerability means remote attackers can exploit it without requiring any user interaction. While the integrity impact is limited, unauthorized modifications to WordPress site elements could lead to defacement, SEO poisoning, or serve as a foothold for further attacks.

Root Cause

The root cause of CVE-2026-32370 is CWE-862: Missing Authorization. The Influencer theme code fails to verify that the user making a request has the appropriate permissions before executing the requested action. This fundamental security control gap means that certain theme functions can be invoked by any visitor to the site, regardless of whether they are logged in or have appropriate privileges.

Attack Vector

The attack vector is network-based, requiring no authentication and no user interaction. An attacker can directly send crafted HTTP requests to vulnerable endpoints exposed by the Influencer theme. Since no privilege escalation is required (the attacker needs no prior access), the attack surface is accessible to any remote attacker who can reach the WordPress installation.

The exploitation path typically involves:

1. Identifying WordPress sites running the vulnerable Influencer theme
2. Crafting requests to theme endpoints that lack authorization checks
3. Submitting requests to perform unauthorized modifications
4. Successfully modifying site content or settings without authentication

Detection Methods for CVE-2026-32370

Indicators of Compromise

• Unexpected modifications to WordPress theme settings or content without corresponding admin activity logs
• HTTP requests to Influencer theme endpoints from unauthenticated sessions showing successful responses
• Unusual patterns of POST requests targeting theme-specific AJAX handlers or REST endpoints
• Web server logs showing successful requests to theme endpoints without accompanying authentication cookies

Detection Strategies

• Monitor WordPress access logs for suspicious requests to Influencer theme endpoints from unauthenticated users
• Implement Web Application Firewall (WAF) rules to detect and block requests attempting to bypass authorization
• Review WordPress audit logs for content or settings changes that don't correlate with admin user sessions
• Deploy file integrity monitoring to detect unauthorized modifications to theme-related content

Monitoring Recommendations

• Enable comprehensive WordPress activity logging to track all administrative actions
• Configure alerts for theme settings modifications occurring outside normal administrative workflows
• Implement rate limiting on theme endpoints to reduce automated exploitation attempts
• Regularly audit installed theme versions against known vulnerability databases

How to Mitigate CVE-2026-32370

Immediate Actions Required

• Verify if your WordPress installation uses the Influencer theme by raratheme
• Check the current theme version against the vulnerable range (version 1.1.7 and earlier)
• Update the Influencer theme to a patched version when available from the vendor
• Consider temporarily switching to a different theme if no patch is available

Patch Information

This vulnerability affects the Influencer theme version 1.1.7 and all prior versions. Site administrators should check for theme updates through the WordPress admin dashboard or the raratheme vendor website. For the latest patch status and remediation guidance, consult the Patchstack Vulnerability Advisory.

Workarounds

• Implement a Web Application Firewall (WAF) with rules to restrict access to vulnerable theme endpoints
• Use WordPress security plugins to add additional authorization layers to theme functionality
• Restrict access to the WordPress admin area and theme-specific endpoints via IP allowlisting where feasible
• Enable additional logging and monitoring to detect exploitation attempts while awaiting a vendor patch

# Example .htaccess configuration to restrict theme endpoint access
# Add to WordPress root .htaccess file
<IfModule mod_rewrite.c>
RewriteEngine On
# Block unauthenticated requests to theme AJAX endpoints
RewriteCond %{REQUEST_URI} ^/wp-content/themes/influencer/.*\.php$ [NC]
RewriteCond %{HTTP_COOKIE} !wordpress_logged_in [NC]
RewriteRule .* - [F,L]
</IfModule>
