## What is CVE-2026-54607?

CVE-2026-54607 is a high-severity server-side request forgery vulnerability in labring FastGPT, published on 7 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

FastGPT is a knowledge-based AI application platform. Prior to 4.15.0-beta4, the HTTP-tool OpenAPI schema importer validates only the top-level URL before passing it to SwaggerParser.bundle, whose remote reference resolver fetches $ref URLs without FastGPT's internal-address guard and returns fetched content inline, allowing an authenticated team member to read internal services or cloud metadata. This issue is fixed in version 4.15.0-beta4.

Weakness: CWE-918 (Server-Side Request Forgery)
