CVE-2026-48204 camel vulnerability
Improper Input Validation, Improper Access Control vulnerability in Apache Camel in Camel Mongodb Gridfs component. The camel-mongodb-gridfs producer selects the GridFS operation to perform from the gridfs.operation Exchange header when the endpoint's operation parameter is not set - which is the default. The control-header constants (GridFsConstants.GRIDFS_OPERATION, GRIDFS_OBJECT_ID, GRIDFS_METADATA, GRIDFS_CHUNKSIZE, GRIDFS_FILE_ID_PRODUCED) were the plain strings gridfs.operation, gridfs.objectid, gridfs.metadata, gridfs.chunksize and gridfs.fileid. Because these names do not start with the Camel / camel prefix, HttpHeaderFilterStrategy - which blocks only the Camel header namespace on the HTTP boundary - let them pass from an inbound HTTP request straight into the Exchange. In a route that bridges an HTTP consumer (for example platform-http) into a mongodb-gridfs: producer with no explicit operation, any HTTP client could therefore set the gridfs.operation header to override the route's intended operation - switching, for example, a file upload to remove (deleting a file identified by the attacker-supplied gridfs.objectid), listAll (enumerating every file in the bucket) or findOne (reading a file) - and supply a gridfs.metadata value that is parsed as a MongoDB document, enabling NoSQL operator injection. No credentials are required when the bridging consumer is unauthenticated. This issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0. Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. After upgrading, routes that drive GridFS operations or metadata via the raw header names must use CamelGridFsOperation / CamelGridFsObjectId / CamelGridFsMetadata / CamelGridFsChunkSize / CamelGridFsFileId instead of the gridfs.* names. For deployments that cannot upgrade immediately, set an explicit operation on the mongodb-gridfs: endpoint so the operation is not taken from a header, and strip the gridfs.* headers from any untrusted ingress before the producer.
Quick answer
apache camel should be reviewed and updated if it matches the affected versions. The recommended fix is to apply the vendor-supported patched version or the mitigation steps below, then retest the public website with Fixnx.

How to fix it
CVE-2026-48204 affects Apache Camel in Camel Mongodb Gridfs. Upgrade Apache Camel on the deployed branch to a fixed release (4.14.8, 4.18.3, 4.21.0) and review routes that expose this component to external or user-controlled messages. Affected ranges in the local NVD record are 4.0.0 through before 4.14.8; 4.15.0 through before 4.18.3; 4.19.0 through before 4.21.0.
- Inventory every service, integration route, container image, and build manifest that includes Apache Camel in Camel Mongodb Gridfs or transitive Camel modules related to in Camel Mongodb Gridfs.
- Compare each deployed Camel version with the affected ranges for CVE-2026-48204; treat 4.0.x-4.14.7, 4.15.x-4.18.2, and 4.19.x-4.20.x as needing an upgrade when the component is present.
- Upgrade to the fixed Camel release for the active branch: 4.14.8, 4.18.3, 4.21.0, or a later vendor-supported release.
- Rebuild application artifacts and container images from a clean dependency lockfile so no vulnerable Camel module remains through transitive dependencies.
- Harden exposed routes by filtering user-controlled Camel headers and component-specific control headers before data reaches Camel producers or internal route logic.
- Rotate credentials or integration tokens if logs, routing headers, backend endpoints, or message contents may have been exposed or redirected through the vulnerable route.
- Deploy first to staging, run regression tests for the impacted route, then promote to production with monitoring for routing errors, authorization failures, SSRF attempts, and unexpected message destinations.

Verify the fix
- Confirm dependency output shows Apache Camel 4.14.8, 4.18.3, 4.21.0 or a later fixed release in every affected application.
- Run route-level tests that replay malicious or unexpected headers and verify they are removed, ignored, or rejected before reaching Camel internals.
- Check application logs after deployment for exceptions, leaked stack traces, SSRF indicators, unauthorized backend operations, or unexpected route destinations.
- Open the generated Fixnx page and confirm the canonical URL ends with camel-cve-2026-48204.
- Re-run sitemap validation and confirm camel-cve-2026-48204 appears once in sitemap.xml with the full CVE-2026-48204 suffix.
