CVE-2025-2482 in Gotcha Plugin
Summary
by MITRE • 03/22/2025
The Gotcha | Gesture-based Captcha plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'menu' parameter in all versions up to, and including, 1.0.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The vulnerability identified as CVE-2025-2482 affects the Gotcha | Gesture-based Captcha plugin for WordPress, specifically targeting versions up to and including 1.0.0. This represents a critical security flaw that undermines the integrity of web applications by enabling malicious actors to exploit a reflected cross-site scripting vulnerability. The vulnerability stems from inadequate input validation and output escaping mechanisms within the plugin's codebase, creating an attack vector that can be leveraged by unauthenticated threat actors without requiring any privileged access or authentication credentials.
The technical flaw manifests through the 'menu' parameter which is not properly sanitized before being processed and rendered in web responses. This parameter serves as an entry point for attackers to inject malicious scripts that will execute in the context of a victim's browser when they interact with the compromised website. The reflected nature of this vulnerability means that the malicious script code is embedded within a URL or HTTP request and then reflected back to the victim's browser, making it particularly dangerous as it can be delivered through various attack vectors including phishing emails, compromised advertisements, or malicious links shared through social media platforms.
The operational impact of this vulnerability extends beyond simple script execution, as it creates potential pathways for more sophisticated attacks such as session hijacking, credential theft, or redirection to malicious websites. Attackers can craft specially designed URLs containing malicious payloads that, when clicked by unsuspecting users, execute scripts that can steal cookies, modify page content, or redirect users to fraudulent sites. This vulnerability particularly affects WordPress environments where the plugin is installed and active, potentially compromising thousands of websites that have not yet updated to patched versions. The attack surface is broad since the vulnerability affects all versions up to 1.0.0, indicating a widespread exposure across numerous installations that may not be actively monitored or maintained.
Security professionals should consider this vulnerability in relation to CWE-79 which specifically addresses cross-site scripting flaws in software applications. The ATT&CK framework categorizes this type of vulnerability under T1203 - Exploitation for Client Execution, where adversaries leverage application vulnerabilities to execute malicious code on target systems. Organizations should implement immediate mitigation strategies including updating to patched versions of the plugin, implementing web application firewalls, and conducting thorough security audits of all installed WordPress plugins. Additionally, administrators should educate users about the dangers of clicking suspicious links and implement proper input validation and output escaping mechanisms throughout their web applications to prevent similar vulnerabilities from occurring in other components of their digital infrastructure.
The remediation approach requires immediate attention from WordPress administrators who must upgrade the Gotcha plugin to the latest available version that addresses this specific vulnerability. Security monitoring should be enhanced to detect unusual patterns in traffic related to the affected parameter, and comprehensive security assessments should be performed to identify any other potentially vulnerable components within the WordPress ecosystem. The vulnerability serves as a reminder of the critical importance of maintaining up-to-date software components and implementing robust security practices including regular vulnerability scanning, input validation, and proper output encoding to protect against reflected cross-site scripting attacks that continue to represent one of the most prevalent web application security risks.
