Karakeep's Reddit plugin content bypasses DOMPurify sanitization, enabling stored XSS
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
Karakeep is a elf-hostable bookmark-everything app. In version 0.30.0, when the Reddit metascraper plugin returns readableContentHtml, the HTML parsing subprocess uses it directly without running it through DOMPurify. Every other content source in the crawler goes through Readability + DOMPurify, but the Reddit path skips both. Since this content ends up in dangerouslySetInnerHTML in the reader view, any malicious HTML in the Reddit response gets executed in the user's browser. Version 0.31.0 contains a patch for this issue.
