CVE-2025-62184 is a stored Cross-site Scripting (XSS) vulnerability classified under CWE-79, found in Pegasystems Pega Infinity platform versions 8.1.0 through 25.1.0. The flaw arises from improper neutralization of user-supplied input during web page generation in a user interface component, allowing malicious scripts to be stored and later executed in the context of other users viewing the affected pages. Exploitation requires an administrative user with extensive access rights to inject the malicious payload, which limits the attack vector primarily to insiders or compromised admin accounts. The vulnerability does not impact data integrity and has a low impact on confidentiality, as the attacker’s capabilities are constrained by the existing privileges. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:H means high privileges required), user interaction required (UI:P), and low confidentiality impact (VC:L). No known public exploits have been reported, and no patches are currently linked, suggesting that remediation may require vendor updates or configuration changes. Given the nature of stored XSS, successful exploitation could lead to session hijacking, defacement, or phishing attacks within the administrative interface, potentially facilitating further compromise if combined with other vulnerabilities or misconfigurations.

The primary impact of this vulnerability is the potential execution of malicious scripts within the administrative interface of Pega Infinity, which could lead to session hijacking, unauthorized actions, or phishing attacks targeting privileged users. Although the confidentiality impact is low and integrity is unaffected, the exploitation requires administrative privileges, which limits the threat to insider attackers or adversaries who have already compromised an admin account. Organizations relying on Pega Infinity for critical business processes may face risks of lateral movement or privilege escalation if attackers leverage this XSS flaw as part of a broader attack chain. The vulnerability could undermine trust in the platform’s administrative interface and potentially disrupt business operations if exploited. Since no known exploits exist in the wild, the immediate risk is moderate, but the presence of this vulnerability in widely used versions means it could become a target once exploit code is developed.

To mitigate CVE-2025-62184, organizations should first verify if they are running affected versions of Pega Infinity (8.1.0 through 25.1.0) and restrict administrative access to trusted personnel only. Implement strict input validation and output encoding on all user-supplied data within the administrative UI components to prevent script injection. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in the browser context. Monitor administrative accounts for unusual activity and enforce multi-factor authentication to reduce the risk of compromised credentials. Regularly review and update access controls to minimize the number of users with administrative privileges. Stay in contact with Pegasystems for official patches or security advisories addressing this vulnerability and apply updates promptly once available. Additionally, conduct security awareness training for administrators to recognize phishing or social engineering attempts that could lead to account compromise. Consider deploying web application firewalls (WAFs) with custom rules to detect and block XSS payloads targeting the Pega Infinity interface.
