Arbitrary file read via encoded path traversal
Published May 28, 2026 · Updated May 28, 2026
Path traversal in DeepCode through commit c991dc2 allows remote attackers to read arbitrary files through the SPA catch-all route. The route joins decoded full_path input to FRONTEND_DIST without resolving the result or verifying containment, so encoded separators and dot segments escape the directory. Exploitation requires network access to a Docker/production-mode server and exposes files readable by the DeepCode process.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=1.2.0
- Affected versionversion=0 <=c991dc22e67958a031f2e20595128a6a5fbd8f3d
