CVE-2026-55434 PUBLISHED

Coder vulnerable to denial of service via unbounded request body in AI Bridge provider endpoints

Assigner: GitHub_M
Reserved: 16.06.2026 Published: 07.07.2026 Updated: 08.07.2026

Coder allows organizations to provision remote development environments via Terraform. Starting in version 2.33.0 and prior to versions 2.33.8 and 2.34.2, AI Bridge provider handlers read request bodies with io.ReadAll without a maximum size so an authenticated user with AI Bridge access could send an arbitrarily large body and exhaust memory. Exploitation requires authenticated access to the AI Bridge endpoints and the impact is limited to availability (denial of service). Versions 2.33.8 and 2.34.2 patch the issue. No known workarounds are available.
