CVE-2025-47583: Salon Booking System CSRF Vulnerability

CVE-2025-47583 Overview

CVE-2025-47583 is a Cross-Site Request Forgery (CSRF) vulnerability in the Dimitri Grassi Salon booking system WordPress plugin (salon-booking-system). The flaw affects all plugin versions up to and including 10.16. According to the Patchstack advisory, the CSRF weakness can be abused to trigger arbitrary content deletion when an authenticated user visits an attacker-controlled page. The vulnerability is tracked under CWE-352: Cross-Site Request Forgery.

Critical Impact
An attacker can trick an authenticated administrator into performing unintended state-changing actions, including arbitrary content deletion within the salon booking system.

Affected Products

Dimitri Grassi Salon booking system (salon-booking-system) WordPress plugin
All versions from n/a through 10.16
WordPress sites running the vulnerable plugin with authenticated administrators

Technical Details for CVE-2025-47583

Vulnerability Analysis

The Salon booking system plugin exposes state-changing endpoints that do not properly verify the origin of incoming requests. WordPress plugins are expected to validate nonces on privileged actions using functions such as wp_verify_nonce() or check_admin_referer(). When these controls are missing or incorrectly implemented, an attacker can craft a malicious page that submits forged requests using the victim's authenticated session.

The Patchstack advisory characterizes the impact as arbitrary content deletion, meaning the forged request can remove data managed by the plugin. The attack requires user interaction, as the victim must load the attacker's page while authenticated to the target WordPress site.

Root Cause

The root cause is missing or insufficient CSRF token validation on privileged plugin actions. WordPress provides a nonce mechanism specifically to bind requests to a user session, and the vulnerable code paths do not enforce this control before performing deletion operations.

Attack Vector

The attack vector is network-based and requires user interaction. An attacker hosts a page containing a crafted form or JavaScript payload that issues a request to the vulnerable plugin endpoint. When an authenticated administrator visits the malicious page, the browser automatically attaches session cookies, and the request executes with the victim's privileges.

No verified proof-of-concept code is publicly available. Refer to the Patchstack advisory for CVE-2025-47583 for additional technical context.

Detection Methods for CVE-2025-47583

Indicators of Compromise

Unexpected deletion of salon bookings, services, or related content records within the WordPress database.
HTTP POST requests to salon-booking-system admin endpoints with Referer or Origin headers pointing to external domains.
Administrator sessions performing deletion actions immediately after visiting untrusted external links.

Detection Strategies

Review WordPress audit logs for content deletion events that do not correlate with legitimate administrator workflows.
Inspect web server access logs for requests to plugin action handlers containing off-site Referer headers.
Monitor for unusual browser-initiated POST requests originating during administrator browsing sessions.

Monitoring Recommendations

Enable a WordPress activity logging plugin to capture content deletion events, user identity, and source IP.
Forward web server and application logs to a centralized log analytics platform for correlation.
Alert on deletion volumes that exceed a baseline for the affected content types managed by salon-booking-system.

How to Mitigate CVE-2025-47583

Immediate Actions Required

Identify all WordPress sites running the salon-booking-system plugin at version 10.16 or earlier.
Restrict administrative browsing to trusted sites and require administrators to log out when not actively managing the site.
Back up plugin data so that unauthorized deletions can be reversed if exploitation occurs.

Patch Information

Refer to the Patchstack advisory for CVE-2025-47583 for the latest fixed version information. Update the plugin to a release later than 10.16 once the vendor publishes a patched version.

Workarounds

Deactivate the salon-booking-system plugin until a patched version is installed if the booking functionality is not actively required.
Deploy a Web Application Firewall (WAF) rule that blocks POST requests to plugin endpoints when the Referer or Origin header does not match the site domain.
Enforce browser isolation or separate administrative browser profiles to reduce the risk of session-riding attacks.

bash

# Example WAF pseudo-rule: block cross-origin POSTs to plugin endpoints
# Adjust to your WAF syntax (ModSecurity, Cloudflare, AWS WAF, etc.)

  "chain,phase:1,deny,status:403,id:1004758,\
