    "summary": "Deserialization of Untrusted Data vulnerability in Apache Camel PQC Component. The camel-pqc component persists post-quantum key metadata (KeyMetadata) through pluggable KeyLifecycleManager implementations. AwsSecretsManagerKeyLifecycleManager.deserializeMetadata() reads that metadata back from the configured AWS Secrets Manager secret by Base64-decoding the stored value and deserializing it with a raw java.io.ObjectInputStream.readObject() and no ObjectInputFilter or class allow-list; the cast to KeyMetadata happens only after readObject() returns, so any readObject() side effects in a crafted object run before the type check. A principal who can write to the AWS Secrets Manager secret that holds this metadata (requiring secretsmanager:PutSecretValue on that secret) could store a crafted serialized object that is deserialized during normal key-lifecycle operations, potentially leading to code execution in the context of the application that manages the keys. This is the same underlying defect, in the same code path and remediated by the same fix, as CVE-2026-46590, which was reported independently and additionally covers the HashiCorp Vault and file-based sibling managers; both are incomplete-remediation follow-ons to CVE-2026-40048 (CAMEL-23200). This issue affects Apache Camel: from 4.18.0 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 4.18.x LTS releases stream, then they are suggest",
