Mitigating Controls (NIST 800-53 r5) AI

IA-11 Re-authentication good match
prevent

Directly requires re-authentication before allowing a password change, blocking the session-only bypass described in CVE-2026-44733.

IA-5 Authenticator Management good match
prevent

Mandates verification of identity and enforcement of password-change rules, directly addressing the unverified change flaw (CWE-620).

AC-3 Access Enforcement partial match
prevent

Enforces access-control decisions on the /api/v3/users/me PATCH endpoint so that password modification cannot succeed without proper authorization checks.

Mitigating Controls (NIST CSF 2.0) AI

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

PR.AA-01 mostly match
prevents

Credential management practices directly enforce re-authentication for password changes.

PR.AA-03 mostly match
prevents

Authentication requirements include verifying identity before allowing credential modifications.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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.5.17 Authentication information partial match
degrades

Requires secure management of authentication information, directly addressing the need to verify the original password before allowing a change.

A.8.5 Secure authentication partial match
prevents

Mandates secure authentication mechanisms, which include verifying existing credentials before permitting password changes.

A.5.16 Identity management none match
none

Identity management processes can incorporate verification steps, but the control itself does not explicitly require password-change verification.

A.8.3 Information access restriction none match
none

Information access restriction can be strengthened by password verification, yet the control focuses on access rights rather than change procedures.
