CVE-2026-54607 is a high-severity vulnerability rated 7.7/10 on the CVSS scale. 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. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
