CVE-2022-0766: Server-Side Request Forgery in calibreweb

March 8, 2022 (updated October 27, 2026)

calibreweb prior to version 0.6.17 is vulnerable to server-side request forgery (SSRF). This is due to an incomplete fix for CVE-2022-0339. The blacklist does not check for 0.0.0.0, which would result in a payload of 0.0.0.0 resolving to localhost.
