The vulnerability affected versions 9.0.0.M1 through 9.0.37, and the fix was included in the upstream 9.0.37 release (July 2020). When TuxCare onboarded version 9.0.39 in October 2026, the upstream code already contained the fix that validates WebSocket payload length and rejects frames with the MSB set in 64-bit payload encodings.
