CVE-2026-19054Public exploit

Arbitrary file access via unchecked path resolution

Published Aug 6, 2026 · Updated Aug 6, 2026

Path traversal in Lspace lspace-server 1.0.0 allows local users to read, overwrite, or delete host files through repository file APIs. The affected methods pass caller-controlled filePath values to path.resolve without verifying that the result remains beneath the repository root. A caller must already be able to invoke the file APIs, and resulting access is limited to files permitted to the server process.
