    Summary: Denial of Service in ecstatic

    Details: `ecstatic`, a simple static file server middleware, is vulnerable to denial of service. If a payload with a large number of null bytes (`%00`) is provided by an attacker it can crash ecstatic by running it out of memory. [Results from the original advisory](https://www.checkmarx.com/advisories/denial-of-service-dos-vulnerability-in-ecstatic-npm-package/) ``` A payload of 22kB caused a lag of 1 second, A payload of 35kB caused a lag of 3 seconds, A payload of 86kB caused the server to crash ``` ## Recommendation Update to version 2.0.0 or later.
