Summary

CVE-2026-13761 is a high-severity Unchecked Input for Loop Condition (CWE-606) vulnerability in Pega Platform (inferred from references). Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked at the 17th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) — see the control section below for these in your framework.

prevents

Secure development lifecycle requires input validation and bounds checking that can prevent unchecked loop conditions.

prevents

Application security requirements include input validation rules that mitigate excessive looping from untrusted data.

prevents

Secure coding standards directly mandate validation of loop-control inputs to prevent unbounded iteration.

finds

Security testing in development can detect and block unchecked loop conditions before release.
