Description
### Impact An attacker who can supply input to `decodeUriComponent()` (directly or via a dependency that uses this package on URL/query/path data) can cause excessive CPU usage and application unresponsiveness. This is an availability issue; there is no known memory corruption, data disclosure, or remote code execution impact. ### Patches Upgrade to `decode-uri-component@0.5.0`. ### Workarounds Limit the size of the input.
