Relative Path Traversal Vulnerability in Apache Camel Google Storage Component

CVE-2026-66907

What is CVE-2026-66907?

A relative path traversal vulnerability exists in the Apache Camel Google Storage component, allowing unauthorized file overwrite on the local filesystem. When the downloadFileName option is set without proper filtering or normalization, it constructs local paths that may lead outside the intended directory, enabling an attacker to influence file names in the consumed bucket. This defect arises because the object names, stored as opaque UTF-8 keys, can include parent-directory segments. Users are advised to upgrade to version 4.22.0 or 4.14.9 if on the LTS stream, and apply filtering or explicit expressions to mitigate the risk.
