Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-23 Session Authenticity
addresses: CWE-614

Forces the Secure flag on session cookies, preventing their transmission over unauthenticated HTTP channels.

SC-8 Transmission Confidentiality and Integrity
addresses: CWE-614

Enforcing confidentiality on transmitted sensitive cookies requires the Secure attribute, preventing exposure on insecure channels.

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.DS-02 partial match
blocks

Setting the Secure attribute is a direct mechanism for protecting sensitive session data in transit over HTTPS.

PR.PS-01 partial match
blocks

Enforcing hardened configuration baselines includes requiring the Secure flag on sensitive cookies.

PR.PS-06 partial match
blocks

Secure SDLC practices explicitly require correct use of security attributes such as the cookie Secure flag.

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.8.26 Application security requirements partial match
blocks

A.8.26 only requires that security requirements (including those that could address cookie flags via 8.24 cryptography or other guidance) be identified and specified during development; it does not itself enforce, implement, or stop exploitation of the missing Secure attribute.

A.8.27 Secure system architecture and engineering principles partial match
removes
A.8.28 Secure coding partial match
prevents

Secure coding practices directly prevent missing the Secure attribute on sensitive cookies, though the control covers many other coding issues.

A.8.5 Secure authentication partial match
degrades

Secure authentication control requires protection of session credentials, directly addressed by setting the Secure flag on sensitive cookies.

A.8.8 Management of technical vulnerabilities partial match
