Kerentanan Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') pada localhostlabs karakeep. Skor CVSS 3.1 6.1 (Medium) menurut NVD.

Deskripsi (NVD)

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.
