Kavita 0.9.0 through 0.9.1.4 contains a server-side request forgery vulnerability that allows authenticated users to bypass the SSRF blocklist through DNS rebinding or HTTPS redirects. Attackers can submit a URL to POST /api/Cbl/upload-cbl-file whose host rebinds or redirects to internal addresses after validation, enabling blind internal port and service probing.
