GHSA-xr9w-x6gw-c9mj: Duplicate advisory: Deno vulnerable to Regular Expression Denial of Service
(updated )
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-jc97-h3h9-7xh6. This link is maintained to preserve external references.
Original Description
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. This issue has been patched in version 1.31.0.
