CVE-2026-40048: Camel pqc Camel-PQC Vulnerable To Deserialization Of Vulnerability
HIGHCVE-2026-40048 is a HIGH (CVSS 7.8) camel-pqc vulnerable to deserialization of vulnerability (CWE-502: Deserialization of Untrusted Data) affecting Camel pqc libraries in the Maven ecosystem. The issue involves camel-pqc vulnerable to deserialization of untrusted data. Remediation is available by upgrading affected packages to version 4.18.2.
CVE-2026-40048 at a Glance
Security Impact
CVSS: 7.8
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2026-40048
To remediate this vulnerability, upgrade all affected Camel pqc dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-pqc</artifactId>
<version>4.18.2</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.apache.camelHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-40048, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.apache.camelAnalyze the terminal output to locate any version of Camel pqc in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.18.2), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.apache.camel command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Camel pqc, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "The Camel-PQC FileBasedKeyLifecycleManager class deserializes the contents of `<keyId>.key` files in the configured key directory using java.io.ObjectInputStream without applying any ObjectInputFilter or class-loading restrictions. The cast to `java.security.KeyPair` is evaluated only after `readObject()` has already returned, so any `readObject()` side effects in the deserialized object run before the type check. An attacker who can write to the key directory used by a Camel application — for example through a path traversal into the directory, misconfigured filesystem permissions on the volume where keys are stored, a compromised key provisioning pipeline, or a symlink attack — can place a crafted serialized Java object that, when deserialized during normal key lifecycle operations, results in arbitrary code execution in the context of the application.\n\nThis issue affects Apache Camel: from 4.19.0 before 4.20.0, from 4.18.0 before 4.18.2.\n\nUsers are recommended to upgrade to version 4.20.0, which fixes the issue by replacing java.io.ObjectInputStream-based key and metadata storage with standard PKCS#8 (private key) / X.509 SubjectPublicKeyInfo (public key) Base64 JSON encoding. For users on the 4.18.x LTS releases stream, upgrade to 4.18.2.",
