CVE-2026-85248— Apache Camel: Camel-PQC Signature Verification Bypass via a Shared Unsynchronized Signature Instance

Quick assessment

Affected
Apache Software Foundation Apache Camel
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache Camel PQC 组件中存在“共享资源并发执行且同步不当”（竞态条件）漏洞。 该问题影响 Apache Camel 的以下版本范围： 从 4.12.0 到 4.18.5（不含 4.18.5） 从 4.19.0 到 4.22.1（不含 4.22.1） 在受影响版本中，生产者持有一个单一的 实例，并在未进行同步控制的情况下，将其用于所有消息交换。 对象是状态化的且非线程安全：其 方法会累积待签名或验证的数据，而 方法则会消耗该累积状态。当多个并发消息交换共享同一个实例时，不同消息的 和 调用会发生交错，

Vulnerability Title
Apache Camel: Camel-PQC Signature Verification Bypass via a Shared Unsynchronized Signature Instance
Source: CVE Program / CVE List V5
Vulnerability Description
Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') vulnerability in Apache Camel PQC component. This issue affects Apache Camel: from 4.12.0 before 4.18.5, from 4.19.0 before 4.22.1. The producer held a single java.security.Signature instance and used it for every exchange without synchronizing access. Signature is stateful and is not thread safe: update() accumulates the data to be signed or verified, and verify() consumes that accumulated state. With concurrent exchanges sharing one instance the update and verify calls of different messages interleave, so a verification can complete against data that belongs to another exchange, or against a partially accumulated buffer. The outcome is non-deterministic and includes a verification reporting success for a message whose signature was never actually checked, which defeats the guarantee the component exists to provide. Reaching it requires concurrent traffic through the same endpoint, which is the ordinary condition for a Camel route under load. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. The Signature instance is no longer shared across concurrent exchanges. For deployments that cannot upgrade immediately, restrict the affected route to a single concurrent consumer so that no two exchanges use the instance at once.
