Vulnerability Data
Envoy is a cloud-native high-performance edge/middle/service proxy. Envoy's 1.31 is using `oghttp` as the default HTTP/2 codec, and there are potential bugs around stream management in the codec. To resolve this Envoy will switch off the `oghttp2` by default. The…

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation at post-design stages directly exercises control-flow paths and reveals mismatches between implemented and intended behavior.
Requiring a documented development process and supporting tools reduces the chance that incorrect control-flow logic is introduced in the first place.
Flaw identification and remediation processes can locate and correct control-flow errors once they manifest as incorrect runtime behavior.

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.
Secure SDLC practices directly prevent incorrect control-flow implementations via reviews, testing, and static analysis.

Security testing in development and acceptance can detect paths that deviate from intended logic.
Secure development lifecycle processes can catch incorrect control-flow logic during design and code review.
Secure coding standards and reviews directly target flawed control-flow implementations.
Change-management gates may prevent deployment of flawed logic but do not address the coding defect itself.
