Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Exploitation evidence

Detectable: no evidence on record.
No public nuclei template indexed

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade Pegasystems Pega Infinity to Infinity 25.1.1.

AI-suggested

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.

Description

Pega Platform versions 8.1.0 through 25.1.1 are affected by a Stored Cross-site Scripting vulnerability in a user interface component. Requires an administrative user and given extensive access rights, impact to Confidentiality and Integrity are low.

Impact

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.
