## Technical details

The vulnerability is an improper validation of inputs used for loop conditions (CWE-690 / loop-related input validation failure). The flaw affects Pega Platform versions 7.1.0 through 25.1.2. Without proper bounds checking on loop condition inputs, an attacker can provide specially crafted input that triggers excessive iteration, exhausting system resources and causing denial of service. The attack vector is network-accessible if the affected component is exposed; no authentication bypass is required to trigger the excessive looping. Patches and hotfixes have been released for multiple version branches (23.1.5, 24.1.4, 24.2.5, 25.1.3+, 26.1).

## Affected products
