What is CVE-2021-39358?

In GNOME's libgfbgraph up to version 0.2.4, the gfbgraph-photo.c component lacks TLS certificate verification in the SoupSessionSync objects. This oversight leaves users exposed to potential man-in-the-middle (MITM) attacks, where an attacker can intercept and manipulate the communication between the user and the intended service. It is imperative for users of libgfbgraph to understand the risks posed by this vulnerability and take necessary precautions.
