CVE-2025-27098Public exploitNetwork attack vector

Server file disclosure via static path traversal

Published Feb 20, 2025 · Updated Feb 20, 2025

Path traversal in GraphQL Mesh before @graphql-mesh/cli 0.82.22 and @graphql-mesh/http 0.3.19 allows remote attackers to read server files. The static-file handler joins a URL-supplied relativePath to the staticFiles base and opens the result without proving it remains beneath that base. Exposure requires staticFiles under serve; a traversal request reads files accessible to the server process.
