CVE-2026-7230 Overview
A Cross-Site Scripting (XSS) vulnerability has been identified in SourceCodester Safety Anger Pad version 1.0. The vulnerability exists in an unknown function where improper handling of the angerDisplay argument allows attackers to inject malicious scripts. This flaw enables remote attackers to execute arbitrary client-side code in the context of a victim's browser session.
Critical Impact
Remote attackers can exploit this XSS vulnerability to execute malicious scripts, potentially leading to session hijacking, credential theft, or defacement of the web application.

Technical Details for CVE-2026-7230
Vulnerability Analysis
This vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-Site Scripting (XSS). The application fails to properly sanitize user-supplied input in the angerDisplay argument before rendering it in the web page output. When a user interacts with a crafted malicious link or page containing the injected payload, the script executes within their browser session with the same privileges as the legitimate application.
The vulnerability requires user interaction to exploit, as the victim must navigate to a page or click a link containing the malicious payload. However, once triggered, the attacker can perform actions on behalf of the authenticated user, steal session tokens, or redirect users to malicious sites.
Root Cause
The root cause of this vulnerability is insufficient input validation and output encoding in the application. The angerDisplay parameter accepts user-controlled data that is subsequently reflected in the HTML response without proper sanitization. This allows attackers to inject arbitrary HTML or JavaScript code that the browser interprets and executes.
Attack Vector
The attack is performed remotely over the network. An attacker crafts a malicious URL or form submission containing XSS payloads in the angerDisplay parameter. When a victim user accesses this crafted input (either through a malicious link, phishing email, or compromised page), the injected script executes in their browser context.
The vulnerability mechanism involves injecting malicious JavaScript through the angerDisplay parameter. When the application processes this input without proper encoding, the script is rendered directly into the HTML output. The exploit has been publicly disclosed, making it accessible to potential attackers. For detailed technical information, refer to the VulDB Vulnerability Report.
Detection Methods for CVE-2026-7230
Indicators of Compromise
- Unusual HTTP requests containing JavaScript or HTML tags in the angerDisplay parameter
- Log entries showing encoded script payloads such as <script>, javascript:, or event handlers like onerror, onload
- Unexpected redirects or iframe injections in application pages
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect and block common XSS payloads in request parameters
- Monitor application logs for suspicious patterns in the angerDisplay parameter including script tags and event handlers
- Deploy browser-based Content Security Policy (CSP) headers to mitigate impact of successful XSS attacks
Monitoring Recommendations
- Enable detailed logging for all HTTP requests containing user input parameters
- Set up alerts for requests matching known XSS payload patterns targeting the angerDisplay field
- Regularly review web server access logs for anomalous request patterns
How to Mitigate CVE-2026-7230
Immediate Actions Required
- Apply input validation to sanitize all user-supplied data in the angerDisplay parameter
- Implement proper output encoding (HTML entity encoding) when rendering user input in web pages
- Deploy Content Security Policy (CSP) headers to restrict inline script execution
Patch Information
No vendor patch information is currently available. Organizations using SourceCodester Safety Anger Pad 1.0 should contact the vendor directly or implement the workarounds below. For updates, monitor the SourceCodester website for security announcements.
Workarounds
- Sanitize all input by implementing server-side validation that strips or encodes HTML special characters from the angerDisplay parameter
- Apply output encoding using context-appropriate encoding functions (e.g., HTML entity encoding) before rendering user data
- Implement strict Content Security Policy headers with script-src 'self' to prevent inline script execution
- Consider using a Web Application Firewall to filter malicious requests until an official patch is available
# Example Content Security Policy header configuration (Apache)
# Add to .htaccess or httpd.conf
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'"
