Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match
prevent

Directly enforces atomic access decisions on one-time tokens, eliminating the TOCTOU window in JdbcOneTimeTokenService.

SI-2 Flaw Remediation good match
prevent

Requires prompt remediation of the identified flaw in Spring Security versions 6.4.x-7.0.x that permits the race condition.

IA-5 Authenticator Management partial match
prevent

Mandates proper management and single-use validation of authenticators (one-time tokens), reducing the impact of check/use races.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly include coding standards and reviews that prevent TOCTOU race conditions.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.17 Clock synchronization none match
none

Reliable, synchronized time across systems narrows the exploitable window in which a resource state can change between a security check and its use.
