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.","published":"2026-02-25T04:16:04.000Z","lastModified":"2026-06-17T10:27:25.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},"cwe":["CWE-79"],"affected":["localhostlabs/karakeep"],"epss":{"score":0.00372,"percentile":0.30947,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.37%).
