CWE-176Improper Handling of Unicode Encoding
Description
The product does not properly handle when an input contains Unicode encoding.
Common consequences
- Integrity→Unexpected State
Potential mitigations
- Architecture and DesignAvoid making decisions based on names of resources (e.g. files) if those resources can have alternate names.
- 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.
