CVE-2026-92034

Information flow enforcement directly requires validating the source of data before allowing transmission or receipt.

Device identification and authentication mandates verifying the source before establishing connections.

Session authenticity mechanisms require validation that communications originate from the expected party.

Boundary protection at interfaces enforces checks on the origin of incoming communications.

Documenting authorized flows supports origin validation by defining expected sources.

Authentication directly verifies the source of users/services/hardware, mitigating origin validation failures.

Verifying identity assertions enforces origin validation for conveyed claims.

Protecting networks from unauthorized access requires origin checks on communication sources.

Network security controls enforce origin validation at network boundaries.

Security of network services includes validating the authenticity of service endpoints.

A.8.26 requires identifying and specifying requirements for resilience against malicious attacks including SQL injections and input validation (items d, j), plus related protections (authentication, segregation, cryptography per 8.24), which can address some but not most origin validation scenarios such as those involving untrusted cross-origin requests or implicit trust in sources.

A.8.27 mandates security-by-design principles (defense-in-depth, least privilege, assume-breach, distrust-external-input, zero-trust verification) plus design reviews that can catch and block origin-validation gaps in many common cases, but leaves a bounded remainder (e.g. protocol-level or third-party component origin errors not surfaced by the organization's review process).

Secure coding practices include implementing proper origin validation to prevent spoofing.
