Summary
An exploitable vulnerability exists in the HTTP client functionality of the Webroot BrightCloud SDK. The configuration of the HTTP client does not enforce a secure connection by default, resulting in a failure to validate TLS certificates. An attacker could impersonate a remote BrightCloud server to exploit this vulnerability.
Exploit prediction
0.73% chance of exploitation in the next 30 days, higher than 54% of all scored CVEs (FIRST EPSS, 2026-11-08).
