NVD description

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.

CVE-2026-27627 pertains to a cross-site scripting (XSS) vulnerability in the Karakeep application, specifically in version 0.30.0. The issue arises from the handling of content fetched from Reddit via the metascraper plugin. When Reddit returns `readableContentHtml`, this HTML content is directly injected into the application's DOM via React's `dangerouslySetInnerHTML` without sanitization through DOMPurify. #Cybersecurity #CVE #HighSeverity #SecurityAlert #RemoteCodeExecution #XSS https://cvetodo.com/cve/CVE-2026-27627
