CVE-2025-62181Network attack vector

Username enumeration via authentication timing discrepancy

Published Dec 10, 2025 · Updated Dec 10, 2025

User enumeration in Pegasystems Pega Infinity 7.1.0 through 25.1.0 allows remote attackers to identify valid usernames during login. The deprecated Basic Credentials authentication service processes valid and invalid usernames with measurably different response times. Unauthenticated network access to that service is sufficient; the disclosure is limited to account validity and does not expose credentials or alter data.
