Summary
CVE-2026-103510 is a critical-severity Failing Open (CWE-636) vulnerability in Perforce (inferred from references). Its CVSS base score is 9.5 (Critical).
Operationally, ranked at the 26th 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 CP-12 (Safe Mode) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
CP-12 forces entry into a safe mode on detected conditions, limiting exposure but not covering every failure path.
SA-8 requires application of engineering principles that include fail-secure design, reducing the likelihood the weakness is introduced.
SC-24 directly requires the system to fail to a known state that preserves security properties, structurally stopping fallback to a less-secure mode.
SI-17 mandates explicit fail-safe procedures that activate on indicated failures, preventing the insecure fallback behavior.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-636, a class-level weakness, and none of its children carries one either.
