Summary
Regular Expression Denial of Service in Deno.upgradeWebSocket API
Details

Impact

Versions of the package deno before 1.31.0 are vulnerable to Regular Expression Denial of Service (ReDoS) due to the upgradeWebSocket function, which contains regexes in the form of /s,s/, used for splitting the Connection/Upgrade header. A specially crafted Connection/Upgrade header can be used to significantly slow down a web socket server.

Patches

It is recommended that users upgrade to Deno 1.31.0.
