As published by the source; long descriptions are shortened.

Relative path traversal vulnerability in Apache Camel Google Storage component. This issue affects Apache Camel: from 4.0.0 before 4.14.9, from 4.15.0 before 4.18.4, from 4.19.0 before 4.22.0. The camel-google-storage consumer downloads Google Cloud Storage objects to the local filesystem when the downloadFileName option is set. That option is documented as a folder or a filename, and when its value contains no expression token the consumer builds the local destination by appending the object name to it: evaluateFileExpression sets the Exchange file-name header to the remote object name and evaluates downloadFileName + "/${file:name}". The ${file:name} token returns the file-name header verbatim, unlike ${file:onlyname}, which applies FileUtil.stripPath to it. The resulting string was passed directly to new File(result) and blob.downloadTo(file.toPath()) with no lexical normalization and no check that the destination stayed inside the configured directory. The object name is not…

# Patch Next advisory brief: CVE-2026-66907

Advisory: Apache Camel-Google-Storage: the consumer appended the remote object name to the configured downloadFileName directory without constraining the result
IDs: CVE-2026-66907, GHSA-f78g-9385-qxqj
Record: https://patchnext.com/advisories/cve-2026-66907 (revision 2, source checked 26 Oct 2026, 16:55 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.apache.camel:camel-google-storage 4.22.0, 4.18.4, 4.14.9. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.apache.camel:camel-google-storage: affected >= 4.0.0, < 4.14.9; >= 4.15.0, < 4.18.4; >= 4.19.0, < 4.22.0; fixed in 4.22.0, 4.14.9, 4.18.4

## Suggested inspection (read-only)
- Maven org.apache.camel:camel-google-storage: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.apache.camel:camel-google-storage.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
