CVE-2025-2160Network attack vector

Browser script execution via undisclosed Mashup flaw

Published Apr 14, 2025 · Updated Apr 14, 2025

Cross-site scripting in Mashup in Pegasystems Pega Infinity 8.4.3 through 24.2.1 allows remote attackers to execute script in a user's browser. Pegasystems has not published the affected Mashup request, field, or output-encoding operation, so the precise untrusted-input path is undisclosed. Exploitation requires user interaction but no attacker privileges; successful script execution permits reading or modifying data available to the browser session without interrupting service.
