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.

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.DS-02 partial match
blocks

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

PR.PS-06 partial match
blocks

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

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.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
blocks

A.8.26 only requires that security requirements (including those that could address query-string exposure) be identified and specified during development; it does not itself enforce, implement or stop exploitation of sensitive data in the query string

A.8.27 Secure system architecture and engineering principles partial match
blocks

Secure architecture principles discourage exposing sensitive data in URLs.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly prohibit placing secrets in query parameters.

A.8.29 Security testing in development and acceptance partial match
finds

Security testing can detect sensitive data leakage via query strings.

A.8.8 Management of technical vulnerabilities partial match
removes
