Vulnerability Title
@astrojs/node: Cache Poisoning due to incorrect error handling when if-match header is malformed
Source: NVD (National Vulnerability Database)
Vulnerability Description
@astrojs/node allows Astro to deploy your SSR site to Node targets. Prior to 10.0.5, requesting a static js/css resources from _astro path with an incorrect/malformed if-match header returns a 500 error with a one year cache lifetime instead of 412 in some cases. This has the effect that all subsequent requests to that file, regardless of if-match header will be served a 5xx error instead of the file until the cache expires. This vulnerability is fixed in 10.0.5.
