CVE-2026-25374: Spa and Salon Auth Bypass Vulnerability

CVE-2026-25374 Overview

A Missing Authorization vulnerability has been identified in the raratheme Spa and Salon WordPress theme (spa-and-salon). This broken access control flaw allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthorized actions within WordPress installations using the affected theme.

Critical Impact

Unauthenticated attackers can bypass authorization checks to perform unauthorized modifications on WordPress sites using the Spa and Salon theme, potentially compromising site integrity.

Affected Products

• Spa and Salon WordPress Theme versions through 1.3.2
• WordPress installations using the vulnerable raratheme theme
• Sites with default theme configurations lacking additional access controls

Technical Details for CVE-2026-25374

Vulnerability Analysis

This vulnerability is classified as CWE-862 (Missing Authorization), indicating that the Spa and Salon WordPress theme fails to properly verify that a user is authorized to perform certain actions. The vulnerability can be exploited remotely over the network without requiring authentication or user interaction, allowing attackers to make unauthorized modifications to affected WordPress installations.

The broken access control stems from missing authorization checks on specific theme functionality, allowing unauthenticated users to access features that should be restricted to authenticated administrators or editors.

Root Cause

The root cause of CVE-2026-25374 is the absence of proper authorization verification in the Spa and Salon theme. WordPress themes should implement capability checks using functions like current_user_can() before executing privileged operations. The affected theme versions through 1.3.2 fail to implement these essential authorization controls, leaving sensitive functionality exposed to unauthorized access.

Attack Vector

The attack vector is network-based with low complexity. An attacker can exploit this vulnerability remotely without authentication by directly accessing vulnerable theme endpoints or AJAX handlers that lack proper authorization checks. The vulnerability allows integrity-impacting modifications without affecting confidentiality or availability of the system.

Since no verified code examples are available, the vulnerability mechanism involves missing current_user_can() or is_admin() checks in theme functions that handle administrative or privileged operations. Detailed technical analysis is available in the Patchstack WordPress Vulnerability Report.

Detection Methods for CVE-2026-25374

Indicators of Compromise

• Unexpected modifications to theme settings or configurations without administrator action
• Suspicious HTTP requests to theme-specific AJAX handlers from unauthenticated sources
• Unusual activity in WordPress access logs targeting /wp-content/themes/spa-and-salon/ endpoints

Detection Strategies

• Review WordPress access logs for unauthorized requests to theme-specific endpoints
• Implement Web Application Firewall (WAF) rules to monitor and block suspicious requests to theme handlers
• Deploy SentinelOne Singularity to detect anomalous file system changes and unauthorized modifications

Monitoring Recommendations

• Enable verbose logging for WordPress AJAX requests and theme function calls
• Monitor for unauthorized changes to theme options in the wp_options database table
• Implement real-time alerting for modifications to theme files or settings outside of normal administrative workflows

How to Mitigate CVE-2026-25374

Immediate Actions Required

• Update the Spa and Salon theme to a patched version when available from raratheme
• Temporarily switch to an alternative theme if a patch is not yet available
• Implement additional access control measures through WordPress security plugins
• Review WordPress user accounts and permissions for any unauthorized changes

Patch Information

Monitor the Patchstack WordPress Vulnerability Report for updates on official patches from raratheme. WordPress administrators should update the Spa and Salon theme to a version newer than 1.3.2 once a security fix is released.

Workarounds

• Implement a Web Application Firewall (WAF) to filter malicious requests targeting the vulnerable theme
• Use WordPress security plugins such as Wordfence or Sucuri to add additional access control layers
• Restrict access to WordPress admin and theme-related endpoints via .htaccess or server configuration
• Consider temporarily disabling the theme and switching to an alternative until a patch is available

# Example .htaccess rule to restrict access to theme directory
<Directory "/var/www/html/wp-content/themes/spa-and-salon/">
    <FilesMatch "\.(php)$">
        Require ip 192.168.1.0/24
        Require ip 10.0.0.0/8
    </FilesMatch>
</Directory>
