CVE-2023-50166Network attack vector

Browser script execution via crafted redirect parameter

Published Jan 31, 2024 · Updated Jun 11, 2025

Cross-site scripting in Pega Platform 8.5.4 through 8.8.3 allows remote attackers to execute script via a crafted redirect parameter. Pegasystems identifies the redirect parameter as the input but has not published the rendering locus or the missing neutralization operation. Exploitation requires an unauthenticated attacker to entice a user into following a malicious link, enabling script execution in that user’s browser context.
