CVE-2025-32310: QuickCal WordPress Plugin CSRF Vulnerability

CVE-2025-32310 Overview

CVE-2025-32310 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the QuickCal - Appointment Booking Calendar plugin for WordPress developed by ThemeMove. This vulnerability allows attackers to perform privilege escalation attacks by tricking authenticated users into executing malicious requests without their knowledge or consent.

The vulnerability exists due to insufficient or missing CSRF token validation in critical plugin functionality. When exploited, an attacker can escalate privileges within the WordPress installation, potentially gaining administrative access to the affected website.

Critical Impact

Successful exploitation of this CSRF vulnerability enables attackers to escalate privileges within WordPress installations, potentially compromising the entire website and its user data.

Affected Products

• QuickCal - Appointment Booking Calendar for WordPress versions through 1.0.15
• WordPress installations with vulnerable QuickCal plugin versions
• Websites using ThemeMove QuickCal for appointment scheduling

Technical Details for CVE-2025-32310

Vulnerability Analysis

This vulnerability is classified under CWE-352 (Cross-Site Request Forgery). CSRF attacks exploit the trust that a web application has in authenticated users' browsers. In the case of the QuickCal plugin, the vulnerability allows attackers to craft malicious requests that, when executed by an authenticated administrator or privileged user, perform unauthorized privilege escalation actions.

The attack chain involves the attacker hosting a malicious page or embedding malicious content that triggers a state-changing request to the vulnerable QuickCal plugin endpoint. When a logged-in WordPress administrator visits the attacker-controlled page, their browser automatically includes their authentication cookies with the forged request, causing the WordPress installation to process the request as if it were legitimate.

Root Cause

The root cause of this vulnerability is the absence or improper implementation of CSRF protection mechanisms (such as nonce verification) in security-sensitive functions within the QuickCal plugin. WordPress provides built-in CSRF protection through its nonce system (wp_nonce_field(), wp_verify_nonce(), check_admin_referer()), but the vulnerable versions of QuickCal fail to properly implement these protections on endpoints that handle privilege-related operations.

Attack Vector

The attack requires social engineering to lure an authenticated WordPress user with sufficient privileges to visit a malicious webpage. The attacker creates a crafted HTML page containing hidden forms or JavaScript that automatically submits requests to the vulnerable QuickCal plugin endpoints. These requests can modify user roles, create new administrator accounts, or alter plugin settings to grant elevated privileges to attacker-controlled accounts.

The vulnerability can be exploited through various delivery mechanisms including:

• Malicious links sent via email or messaging platforms
• Compromised third-party websites that execute cross-origin requests
• Malicious advertisements or embedded content on legitimate websites

Since no verified code examples are available for this vulnerability, organizations should refer to the Patchstack WordPress Vulnerability Report for additional technical details regarding the exploitation mechanism.

Detection Methods for CVE-2025-32310

Indicators of Compromise

• Unexpected changes to WordPress user roles or creation of new administrator accounts
• Suspicious activity in WordPress audit logs showing privilege modifications without corresponding legitimate administrative actions
• HTTP POST requests to QuickCal plugin endpoints from external referrers
• New user accounts with administrative privileges that were not created through normal workflows

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block CSRF attack patterns targeting WordPress plugins
• Monitor WordPress user table for unauthorized role changes or new privileged accounts
• Review HTTP server logs for suspicious requests to QuickCal plugin endpoints with missing or invalid nonce parameters
• Deploy SentinelOne Singularity to detect anomalous behavior patterns associated with privilege escalation attempts

Monitoring Recommendations

• Enable WordPress security logging to capture all user role modifications and administrative actions
• Configure alerts for new administrator account creation or privilege elevation events
• Monitor for outbound connections following privilege escalation that may indicate post-exploitation activity
• Regularly audit WordPress user accounts and their assigned roles

How to Mitigate CVE-2025-32310

Immediate Actions Required

• Update the QuickCal plugin to the latest version that includes CSRF protection patches
• Audit WordPress user accounts for any unauthorized privilege escalations or suspicious administrator accounts
• Review WordPress activity logs for evidence of exploitation
• Consider temporarily disabling the QuickCal plugin until a patched version is confirmed

Patch Information

Organizations should monitor the WordPress plugin repository and ThemeMove's official channels for security updates addressing this vulnerability. The Patchstack advisory provides additional details regarding affected versions and remediation guidance.

Workarounds

• Implement additional CSRF protection at the web server or WAF level for QuickCal plugin endpoints
• Restrict access to WordPress administrative functions to trusted IP addresses
• Enable multi-factor authentication (MFA) for all WordPress administrator accounts to add an additional layer of protection
• Educate administrators about the risks of clicking untrusted links while logged into WordPress

# WordPress security hardening example
# Add to wp-config.php to help mitigate CSRF risks

# Force SSL for admin and logins
define('FORCE_SSL_ADMIN', true);

# Limit login attempts and enable security headers
# These measures complement but do not replace plugin patching
