Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The webbrowser crate, versions before 1.2.2, is vulnerable on Unix platforms. An attacker who can supply a non-HTTP(S) URL to an application using it can inject extra arguments into the browser command, such as enabling a local debugging endpoint or routing traffic through an attacker-controlled proxy, depending on the browser. Upgrade to webbrowser 1.2.2 or later. Applications that only need HTTP(S) URLs can enable the crate's hardened feature as an additional safeguard.
