Arbitrary file read via unvalidated file source path
Published Aug 20, 2026 · Updated Aug 20, 2026
Relative path traversal in the Agent component of Apache InLong before 2.4.0 allows attackers to read arbitrary files via crafted FILE source paths. The Manager OpenAPI accepts a filePath value when creating or modifying FILE stream sources, stores it, and passes it to LogFileSource without validating traversal sequences such as .. . Reachability depends on access to create or update a FILE stream source and on Agent access to the targeted paths, so impact is limited to disclosure of files readable on the Agent host.

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.
