CVE-2026-48204 Apache CVE debrief

Who should care

Users of Apache Camel, particularly those using the Camel Mongodb Gridfs component, should be aware of this vulnerability and take steps to mitigate it. This includes upgrading to a patched version of Apache Camel and implementing defensive measures to prevent exploitation.

Technical summary

The vulnerability exists in the camel-mongodb-gridfs producer, which selects the GridFS operation to perform from the gridfs.operation Exchange header when the endpoint's operation parameter is not set. An attacker can manipulate this header to perform unintended operations, including file deletion, enumeration, and reading. The vulnerability can be exploited without credentials when the bridging consumer is unauthenticated.

Defensive priority

High

Recommended defensive actions

• Upgrade to Apache Camel version 4.21.0 or later
• If using 4.14.x LTS releases, upgrade to 4.14.8
• If using 4.18.x releases, upgrade to 4.18.3
• Set an explicit operation on the mongodb-gridfs: endpoint
• Strip the gridfs.* headers from any untrusted ingress before the producer
• Use CamelGridFsOperation / CamelGridFsObjectId / CamelGridFsMetadata / CamelGridFsChunkSize / CamelGridFsFileId instead of gridfs.* names

Evidence notes

The vulnerability is caused by the use of plain strings for control-header constants, which allows an attacker to manipulate the gridfs.operation header. The issue can be mitigated by upgrading to a patched version of Apache Camel and implementing defensive measures.
