Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Terraform Provider for SendGrid (github.com/arslanbekov/terraform-provider-sendgrid) versions up to and including 1.1.3-0.20250606002314-b4a2dfeb7b0f are affected. If a server's TLS configuration changes between connections so that a client's CA is removed from the trusted list, a resumed TLS session can still succeed without rechecking the certificate against the updated CAs. No fixed version is listed. The source gives few details on exploitation conditions, and no workaround is described.
