Summary
HTML Injection in preact
Details

Versions of preact 10.x on prerelease tags alpha and beta prior to 10.0.0-beta.1 are vulnerable to HTML Injection. Due to insufficient input validation the package allows attackers to inject JavaScript objects as virtual-dom nodes, which may lead to Cross-Site Scripting. This requires user input parsed with JSON.parse() to be passed directly into JSX without sanitization.

Recommendation

Upgrade to version 10.0.0-beta.1.
