How to fix?

Upgrade Wolfi zed to version 0.147.2-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream zed package and not the zed package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

The Tungstenite crate before 0.20.1 for Rust allows remote attackers to cause a denial of service (minutes of CPU consumption) via an excessive length of an HTTP header in a client handshake. The length affects both how many times a parse is attempted (e.g., thousands of times) and the average amount of data for each parse attempt (e.g., millions of bytes).
