CVE-2025-62183 identifies a stored Cross-site Scripting (XSS) vulnerability in Pegasystems Pega Infinity, specifically affecting versions 8.1.0 through 25.1.1. This vulnerability arises from improper neutralization of input during web page generation (CWE-79), allowing an attacker to inject malicious scripts into a user interface component. The stored nature of the XSS means that the malicious payload is saved on the server and executed when other users or administrators view the affected interface. However, exploitation requires the attacker to have administrative privileges with extensive access rights, which significantly limits the attack surface. The CVSS 4.8 score reflects a medium severity, considering the network attack vector, low complexity, no requirement for authentication beyond high privileges, and partial impact on confidentiality and integrity. The vulnerability does not affect availability and does not require user interaction beyond the attacker’s own actions. No public exploits or active exploitation campaigns have been reported to date. The vulnerability was reserved in October 2025 and published in February 2026, indicating recent discovery and disclosure. No official patches are linked yet, but organizations should monitor Pegasystems advisories for updates. The vulnerability’s impact is primarily on confidentiality and integrity, but given the high privilege requirement, the overall risk is moderated. This vulnerability highlights the importance of secure input validation and output encoding in web applications, especially in administrative interfaces that handle sensitive operations.

The potential impact of CVE-2025-62183 is moderate due to the stored XSS allowing malicious script execution within the context of the Pega Infinity administrative interface. If exploited, an attacker with administrative privileges could execute arbitrary scripts, potentially leading to session hijacking, unauthorized actions, or data manipulation within the platform. However, since exploitation requires administrative access, the risk of external attackers leveraging this vulnerability directly is low. The confidentiality and integrity of data managed by Pega Infinity could be compromised if an attacker abuses this flaw, but availability is not affected. Organizations relying heavily on Pega Infinity for critical business processes or customer data management could face operational disruptions or data integrity issues if this vulnerability is exploited internally or by compromised administrators. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially in environments where administrative credentials might be exposed or weakly protected. Overall, the impact is contained but significant enough to warrant timely remediation.

To mitigate CVE-2025-62183, organizations should implement the following specific measures: 1) Apply security patches from Pegasystems promptly once they become available to address the vulnerability directly. 2) Restrict administrative access to Pega Infinity interfaces using strong authentication mechanisms such as multi-factor authentication (MFA) and role-based access controls to minimize the number of users with extensive privileges. 3) Conduct regular audits of administrative accounts and permissions to detect and remove unnecessary or dormant accounts. 4) Implement web application firewalls (WAF) with custom rules to detect and block suspicious input patterns indicative of XSS attacks targeting administrative interfaces. 5) Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts within the application context. 6) Train administrators and developers on secure coding practices, emphasizing proper input validation and output encoding to prevent injection flaws. 7) Monitor logs and user activity for anomalous behavior that could indicate exploitation attempts. 8) Isolate administrative interfaces behind VPNs or internal networks to reduce exposure to external attackers. These targeted actions go beyond generic advice by focusing on privilege restriction, proactive detection, and layered defenses specific to administrative interface vulnerabilities.
