CVE-2026-25747: Apache Camel LevelDB: Deserialization of Untrusted Data in Camel LevelDB

Deserialization of Untrusted Data vulnerability in Apache Camel LevelDB component. The Camel-LevelDB DefaultLevelDBSerializer class deserializes data read from the LevelDB aggregation repository using java.io.ObjectInputStream without applying any ObjectInputFilter or class-loading restrictions. An attacker who can write to the LevelDB database files used by a Camel application can inject a crafted serialized Java object that, when deserialized during normal aggregation repository operations, results in arbitrary code execution in the context of the application. This issue affects Apache Camel: from 4.10.0 before 4.10.8, from 4.14.0 before 4.14.5, from 4.15.0 before 4.18.0. Users are recommended to upgrade to version 4.18.0, which fixes the issue. For the 4.10.x LTS releases, users are recommended to upgrade to 4.10.9, while for 4.14.x LTS releases, users are recommended to upgrade to 4.14.5

Security readout for executives and security teams

Plain-English summary

Apache Camel applications using the LevelDB aggregation repository can be compromised if an attacker can write to that LevelDB store. A crafted serialized Java object may execute code when the application later reads aggregation data. This is serious because successful exploitation can give the attacker the application’s privileges.

Executive priority

Treat as high priority for Camel-based services that use LevelDB aggregation repositories. Prioritize internet-facing or shared-host deployments first, but the key risk is write access to the repository files, not direct unauthenticated network reachability alone.

Technical view

Camel-LevelDB DefaultLevelDBSerializer uses java.io.ObjectInputStream on LevelDB aggregation repository data without ObjectInputFilter or class-loading restrictions. The issue is CWE-502 deserialization of untrusted data and affects Apache Camel 4.10.0 before fixed LTS guidance, 4.14.0 before 4.14.5, and 4.15.0 before 4.18.0.

Likely exposure

Exposure is most likely in Java integration services using org.apache.camel:camel-leveldb for aggregation repositories, especially where LevelDB files are writable by another user, compromised process, shared volume, or deployment pipeline. The source bundle does not prove exposure for Camel deployments that do not use the LevelDB component.

Exploitation context

The bundle lists a public GitHub reference tagged as exploit, but KEV is false and no cited source states active exploitation. Exploitation requires the attacker to write crafted data into LevelDB files used by the Camel application, then wait for normal repository operations to deserialize it.

Researcher notes

The core weakness is unrestricted Java deserialization from a persistence layer. The CVSS vector indicates low-complexity exploitation with low privileges and full confidentiality, integrity, and availability impact. Evidence is incomplete on real-world exploitation and downstream vendor package status beyond the listed references.

Mitigation direction

  • Upgrade Apache Camel to 4.18.0 where applicable.
  • For 4.10.x LTS, follow vendor guidance to upgrade to 4.10.9.
  • For 4.14.x LTS, upgrade to 4.14.5.
  • Restrict write access to LevelDB repository files and backing volumes.
  • Check Apache and distribution vendor guidance for environment-specific packages.

Validation and detection

  • Inventory use of org.apache.camel:camel-leveldb in applications and build manifests.
  • Identify Camel versions in the affected 4.10.x, 4.14.x, and 4.15.x ranges.
  • Confirm whether LevelDB aggregation repositories are enabled in runtime routes.
  • Review filesystem and volume permissions for LevelDB repository paths.
  • Check logs and deployment history for unexpected LevelDB file modifications.
