- 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.
