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.

addresses: CWE-116

Validating that output matches expected content directly mitigates failures to properly encode or escape data for its destination context.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require proper output encoding to prevent injection and message malformation.

prevents

Secure coding standards explicitly require correct output encoding and escaping to preserve message structure.

finds

Security testing can detect missing or incorrect encoding but does not itself implement the control.

prevents

Secure development life cycle mandates output encoding/escaping practices that directly prevent improper encoding.

prevents

Application security requirements include explicit rules for safe output handling and encoding.

prevents

Secure architecture principles reduce the likelihood of missing encoding but do not prescribe the actual technique.
