Technical Details for CVE-2026-105070

Vulnerability Analysis

The vulnerability resides in the Salon booking system plugin for WordPress. According to the Patchstack Vulnerability Report, the plugin assigns privileges incorrectly, allowing an unauthenticated actor to gain elevated rights within the WordPress installation.

The weakness maps to [CWE-266] Incorrect Privilege Assignment. Plugin logic grants capabilities to a user context that should not possess them, bypassing the role separation enforced by WordPress core. Because the attack vector is network-based and no authentication is required, exposure extends to any publicly reachable site running the vulnerable plugin version.

User interaction is required for exploitation, indicating that the attack chain likely involves a crafted request flow completed through a victim action. Once privileges are escalated, the attacker gains the ability to modify site content, install plugins, and execute administrative actions.

Root Cause

The root cause is improper enforcement of privilege boundaries within plugin request handlers. The plugin fails to validate that the acting user holds the required capabilities before granting access to privileged operations or elevating a user's role.

Attack Vector

An attacker crafts a request targeting the vulnerable plugin endpoint and lures a site visitor or administrator into triggering it. The plugin processes the request and assigns elevated privileges without proper authorization checks. No valid credentials are needed by the attacker. Public technical details are limited; refer to the Patchstack Vulnerability Report for additional context.

Detection Methods for CVE-2026-105070

Indicators of Compromise

Unexpected creation of WordPress administrator accounts or role changes on existing accounts
Plugin, theme, or option modifications originating from unauthenticated sessions
Anomalous POST requests to Salon booking system plugin endpoints under /wp-content/plugins/salon-booking-system/
New or modified files in the WordPress installation outside of scheduled maintenance windows

Detection Strategies

Inventory WordPress sites and identify installations running Salon booking system <= 10.31.7
Review wp_users and wp_usermeta tables for unexpected wp_capabilities entries granting administrative roles
Correlate web server access logs with WordPress audit logs to identify role changes tied to unauthenticated requests

Monitoring Recommendations

Enable WordPress audit logging to capture user role and capability changes in real time
Alert on HTTP requests to plugin AJAX or REST endpoints that result in privilege modifications
Monitor for outbound connections initiated by wp-admin processes following suspicious role changes

How to Mitigate CVE-2026-105070

Immediate Actions Required

Update the Salon booking system plugin to a version later than 10.31.7 as soon as a patched release is available
Audit all WordPress user accounts and revoke unauthorized administrator or elevated roles
Rotate credentials for all administrative users on affected sites
Review and remove unauthorized plugins, themes, or files added after the exposure window

Patch Information

Consult the Patchstack Vulnerability Report for the current patched version and vendor advisory. Apply the fixed release through the WordPress plugin updater or by replacing plugin files manually from the vendor source.

Workarounds

Deactivate and remove the Salon booking system plugin until a patched version is installed
Restrict access to the WordPress site using a web application firewall (WAF) rule that blocks requests to vulnerable plugin endpoints
Enforce IP allowlisting on /wp-admin/ and plugin administrative routes where feasible
