CVE-2026-13761Network attack vector

Service interruption via unchecked loop condition

Published Aug 28, 2026 · Updated Aug 28, 2026

Unchecked loop conditions in Pega Infinity 7.1.0 through 25.1.2 allow remote attackers to interrupt service via crafted input. Pega has not disclosed the affected component or input path; published details state only that input reaches loop conditions without adequate validation, causing excessive iteration. The network path requires no privileges or user interaction, and the bounded consequence is resource exhaustion that disrupts service availability.
