CVE-2026-6857
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA flaw was found in camel-infinispan. This vulnerability involves unsafe deserialization in the ProtoStream remote aggregation repository. A remote attacker with low privileges could exploit this by sending specially crafted data, leading to arbitrary code execution. This allows the attacker to gain full control over the affected system, impacting its confidentiality, integrity, and availability.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe camel-infinispan component contains an unsafe deserialization vulnerability in its ProtoStream remote aggregation repository. Attackers can send specially crafted serialized data that, when deserialized by the vulnerable component, allows arbitrary code execution on the target system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify camel-infinispan installationSearch for camel-infinispan in your project dependencies (Maven pom.xml, Gradle build.gradle, or JAR files in the classpath) and check if the camel-infinispan library is present in your deploymentAffected if camel-infinispan library is found in the application dependencies or deployed runtime
-
Determine installed camel-infinispan versionLocate the camel-infinispan JAR file or dependency declaration and record the exact version number, then compare it against any available patched version information from Apache Camel security advisoriesAffected if The installed version has not been patched for the unsafe deserialization vulnerability (no patched version is available for comparison)
-
Verify ProtoStream remote aggregation repository configurationSearch configuration files (XML, YAML, or properties files) for ProtoStream-related configuration, specifically looking for 'ProtoStreamRemoteAggregationRepository' bean definitions or infinispan aggregation repository settingsAffected if ProtoStream remote aggregation repository is configured and enabled in the application
-
Identify exposed ProtoStream endpointsReview your Camel route definitions and web service endpoints for any routes that expose or consume ProtoStream serialization (look for infinispan-related REST endpoints or message consumers)Affected if Endpoints that handle ProtoStream serialization are exposed to network traffic
-
Check network access controlsInspect firewall rules, network policies, or API gateway configurations to determine if access to any ProtoStream-enabled endpoints is restricted to trusted users or networksAffected if ProtoStream endpoints are accessible without authentication or from untrusted network sources
If camel-infinispan is present with ProtoStream remote aggregation repository enabled and exposed to network traffic, the environment is likely affected by this unsafe deserialization vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade camel-infinispan to a patched version that addresses the unsafe deserialization. If immediate patching is not possible, restrict network access to the ProtoStream interface and consider disabling the remote aggregation repository feature.
