Machine-written summary

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

Coder (github.com/coder/coder/v2) versions 2.33.0 before 2.33.8 and 2.34.0 before 2.34.2 are vulnerable. An authenticated user with AI Bridge access can send an arbitrarily large request body to an AI Bridge provider endpoint, exhausting memory and crashing the control plane. Upgrade to version 2.33.8 or 2.34.2. No workaround is listed.
