Common consequences
- Confidentiality,Integrity→Read Files or Directories,Modify Files or Directories
Potential mitigations
- Implementation[object Object]
- ImplementationInputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
