What is CVE-2020-15879?

The Bitwarden Server version 1.35.1 is susceptible to a Server-Side Request Forgery (SSRF) vulnerability. This arises from the software's failure to properly validate specific IPv6 addresses—including those beginning with fc, fd, fe, or ff, as well as the :: address—alongside certain IPv4 addresses like 0.0.0.0/8, 127.0.0.0/8, and 169.254.0.0/16. As a result, attackers can exploit this oversight to send requests originating from the server, potentially enabling unauthorized actions or data exposure.
