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.
Prevents reliance on untrusted matching results for security-relevant decisions by enforcing verification and contest procedures.
Providing authoritative attributes with the data reduces the need for security decisions to rely on untrusted external inputs.
Reduces reliance on untrusted inputs by ensuring only authorized sources may supply data.
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.
Proper management of identities/credentials reduces the chance that security decisions will be driven by untrusted inputs.
Strong authentication mechanisms directly prevent security decisions from depending on modifiable, untrusted inputs.
Verification and protection of identity assertions stops reliance on attacker-controlled values for authorization decisions.
Policy-driven, least-privilege authorization reduces opportunities to bypass controls via tampered inputs.
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.
Monitoring can detect exploitation but does not stop the underlying weakness.
Application security requirements explicitly call for validation of inputs used in security decisions.
A.8.27 mandates security-by-design principles including 'distrust input from external applications', 'least privilege', 'default deny', 'fail securely', zero-trust 'never trust and always verify', end-to-end request encryption, and contextual validation of every request; these directly stop untrusted inputs from influencing security decisions even if the weakness is coded, leaving only a bounded remainder (e.g. non-request decisions or misimplemented principles).
Secure coding standards directly prohibit using untrusted inputs for security-critical decisions.
Security testing in development catches input-validation flaws before deployment.
A.8.3's core (access restriction per policies, identity/group controls, isolation, dynamic techniques with auth/encryption/time-bound rules) directly stops untrusted inputs from influencing security decisions for most instances of CWE-807; the bounded remainder is cases where the decision uses an input outside any access control point (e.g. purely client-side or pre-enforcement computation).
