The primary risk is man-in-the-middle (MITM) attacks. An attacker could intercept your connection and impersonate the server, potentially stealing sensitive data. Self-signed certificates offer no guarantee of authenticity; anyone can create one. Using a trusted CA provides a level of assurance that the server is who it claims to be.
