CVE-2025-49332: WP Time Slots Booking Form CSRF Vulnerability

CVE-2025-49332 Overview

CVE-2025-49332 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the WP Time Slots Booking Form plugin for WordPress, developed by codepeople. The flaw impacts all plugin versions up to and including 1.2.30. An attacker can trick an authenticated user into submitting forged requests that perform unauthorized state-changing actions in the plugin. The vulnerability is tracked under CWE-352: Cross-Site Request Forgery and requires user interaction to succeed. Exploitation typically involves luring a victim to a malicious page while they hold an active WordPress session.

Critical Impact
Successful exploitation allows attackers to perform unauthorized actions in the WP Time Slots Booking Form plugin on behalf of an authenticated WordPress user, with limited integrity impact.

Technical Details for CVE-2025-49332

Vulnerability Analysis

The vulnerability stems from missing or insufficient CSRF protections in the WP Time Slots Booking Form plugin. WordPress provides nonce mechanisms (wp_nonce_field, check_admin_referer, wp_verify_nonce) to defend against forged requests. When these controls are absent or improperly validated, attackers can craft requests that the browser submits automatically using the victim's authenticated session cookies. The result is unauthorized modification of plugin state without the victim's knowledge.

The CVSS vector indicates network-based exploitation with low complexity, no privileges required, but user interaction is necessary. Confidentiality and availability remain unaffected, while integrity carries a low impact rating.

Root Cause

The root cause is the plugin's failure to validate anti-CSRF tokens on state-changing endpoints. Requests processed by the plugin do not verify that they originated from a legitimate user-initiated action within the WordPress admin or front-end context. Any authenticated session visiting an attacker-controlled page can therefore be leveraged to submit requests to the vulnerable endpoints.

Attack Vector

An attacker hosts a malicious page containing a crafted HTML form or JavaScript that auto-submits a request to the target WordPress site. When an authenticated user visits the page, the browser attaches the WordPress session cookie to the request. The plugin processes the request as legitimate, performing the unauthorized action. Refer to the Patchstack Vulnerability Analysis for additional context.

Detection Methods for CVE-2025-49332

Indicators of Compromise

Unexpected modifications to booking form configuration, time slots, or plugin settings without a corresponding admin action.
HTTP POST or GET requests to plugin endpoints containing a Referer header pointing to an external, untrusted domain.
Web server access logs showing plugin actions initiated shortly after an admin visited an unrelated external site.

Detection Strategies

Monitor WordPress audit logs for state-changing operations tied to the wp-time-slots-booking-form plugin that lack a valid nonce parameter.
Alert on requests to plugin endpoints where the Origin or Referer header does not match the site's own domain.
Deploy a Web Application Firewall (WAF) rule to flag POST requests to plugin handlers missing expected nonce fields.

Monitoring Recommendations

Enable verbose WordPress logging via an audit plugin to capture user, IP, and referrer for plugin actions.
Correlate administrator browsing telemetry with plugin configuration changes to identify session-riding patterns.
Track version inventory across WordPress deployments to confirm which sites still run WP Time Slots Booking Form<= 1.2.30.

How to Mitigate CVE-2025-49332

Immediate Actions Required

Update the WP Time Slots Booking Form plugin to a version later than 1.2.30 as soon as a patched release is available from codepeople.
Audit recent booking form configuration changes to confirm no unauthorized modifications occurred.
Restrict administrator browsing to trusted sites while logged into the WordPress admin panel.

Patch Information

At the time of publication, no fixed version is listed in the NVD entry. Administrators should consult the Patchstack Vulnerability Analysis and the codepeople plugin changelog for updated remediation guidance.

Workarounds

Deactivate and remove the WP Time Slots Booking Form plugin until a patched release is available.
Deploy a WAF ruleset that enforces same-origin Referer and Origin header validation for requests to plugin endpoints.
Require administrators to use dedicated browser profiles or sessions for WordPress management to reduce cross-site request exposure.

bash

# Example WAF rule concept: block plugin requests with foreign Referer
# ModSecurity pseudo-rule
SecRule REQUEST_URI "@contains /wp-admin/admin-ajax.php" \
  "chain,deny,status:403,id:1004933,msg:'CSRF: foreign referer to WP Time Slots plugin'"
