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-9 Transmission Confidentiality

addresses: CWE-598

Protects sensitive data placed in query strings from interception in transit when confidentiality controls like HTTPS are enforced.

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.PS-06 mostly match

prevents

Secure SDLC practices directly prevent embedding sensitive data in query strings as part of input-handling and data-flow design.

PR.DS-02 partial match

prevents

HTTPS encryption protects query strings in transit but does not address the root design flaw of placing sensitive data in URLs.

A.8.29 Security testing in development and acceptance mostly match

finds

Security testing can detect sensitive data leakage via query strings.

A.8.12 Data leakage prevention partial match

mitigates

DLP solutions can detect and block sensitive data in URLs.

A.8.20 Networks security partial match

degrades

Network security controls can enforce HTTPS and block sensitive data in URLs.

A.8.26 Application security requirements partial match

prevents

Application security requirements should mandate avoiding sensitive data in query strings.
