CVE-2025-62184 Overview
CVE-2025-62184 is a Stored Cross-Site Scripting (XSS) vulnerability affecting Pega Platform versions 8.1.0 through 25.1.0. The vulnerability exists within a user interface component and allows an attacker with administrative privileges to inject malicious scripts that persist in the application. While the vulnerability requires extensive access rights to exploit, it represents a security risk for organizations using affected Pega Platform deployments.
Critical Impact
Administrative users can inject persistent malicious scripts into the Pega Platform UI component, potentially affecting other administrative users who access the compromised interface.
Affected Products
- Pega Platform versions 8.1.0 through 25.1.0

Technical Details for CVE-2025-62184
Vulnerability Analysis
This Stored Cross-Site Scripting vulnerability (CWE-79) occurs in a Pega Platform user interface component where user-supplied input is not properly sanitized before being stored and rendered back to users. The stored nature of this XSS means malicious payloads persist in the application database and execute whenever the affected page is loaded by other users.
The vulnerability requires an administrative user with extensive access rights to exploit, which significantly limits the attack surface. Given these prerequisites, the confidentiality impact is limited as the attacker would already possess elevated privileges. The vulnerability does not directly impact data integrity or system availability.
Root Cause
The root cause stems from insufficient input validation and output encoding in the affected UI component. When administrative users submit content through the vulnerable interface, the application fails to properly sanitize HTML entities and JavaScript code before storing the input. Subsequently, when this stored content is rendered in the browser, the malicious scripts execute in the context of other users' sessions.
Attack Vector
The attack vector is network-based and requires the following conditions:
- The attacker must possess valid administrative credentials for the Pega Platform
- The attacker must have extensive access rights to the vulnerable UI component
- User interaction is required as a victim must navigate to the page containing the stored payload
Once these conditions are met, an attacker can inject JavaScript code through the vulnerable input field. The malicious script is stored in the backend and executes whenever any user (including other administrators) accesses the affected page. This could potentially be used for session token theft, keylogging, or phishing attacks targeting other administrative users.
The vulnerability is documented in the Pega Security Advisory O25 which provides additional technical context and remediation guidance.
Detection Methods for CVE-2025-62184
Indicators of Compromise
- Unexpected JavaScript or HTML content stored in UI component data fields
- Unusual administrative activity patterns, particularly bulk content modifications
- Browser console errors or unexpected script execution on administrative pages
- Reports from users experiencing unexpected redirects or pop-ups when accessing specific pages
Detection Strategies
- Implement Content Security Policy (CSP) headers with strict directives to detect and block inline script execution
- Monitor application logs for submissions containing suspicious HTML tags such as <script>, <iframe>, or event handlers like onerror
- Deploy Web Application Firewall (WAF) rules to detect and alert on XSS payload patterns in HTTP requests
- Conduct regular code reviews and security scanning of stored content in the database
Monitoring Recommendations
- Enable detailed audit logging for all administrative actions within Pega Platform
- Set up alerts for content submissions containing potentially malicious patterns
- Monitor for unusual session behavior that could indicate session hijacking attempts
- Review CSP violation reports regularly to identify attempted XSS attacks
How to Mitigate CVE-2025-62184
Immediate Actions Required
- Review the Pega Security Advisory O25 for specific remediation steps
- Audit administrative user accounts and ensure principle of least privilege is enforced
- Implement or strengthen Content Security Policy headers to mitigate XSS impact
- Review and sanitize any suspicious content already stored in the affected UI components
Patch Information
Pega has released remediation guidance for this vulnerability. Organizations should consult the Pega Security Advisory O25 for specific patch information and update instructions. Upgrading to a patched version of Pega Platform beyond 25.1.0 is recommended when available.
Workarounds
- Restrict administrative access to only essential personnel until patches can be applied
- Implement strict Content Security Policy headers with script-src 'self' to prevent inline script execution
- Deploy a Web Application Firewall with XSS detection rules in blocking mode
- Conduct input validation at the application layer for all user-submitted content in the affected component
