CVE-2026-46456 -- CVSS 9.8 Vulnerability Briefing

CVE-2026-46456 | CVSS 9.8 (Critical) | Exploit: No known exploit

What Is It

CVE-2026-46456 is a critical improper input validation vulnerability in Apache Camel's AWS2-SQS component, which handles inbound message attribute mapping from Amazon SQS into the Camel Exchange via a component-specific header filter.

Technical Detail

The flaw exists in how the camel-aws2-sqs component processes and maps inbound SQS message attributes into Camel Exchange headers, failing to properly validate that input before use. An attacker with the ability to inject or manipulate SQS message attributes, either by publishing malicious messages to a monitored queue or by controlling upstream message content, could exploit this validation gap to influence downstream processing logic. The full impact scope is not yet publicly detailed, but the CVSS score of 9.8 indicates a likely unauthenticated, network-exploitable condition with high impact to confidentiality, integrity, and availability, consistent with remote code execution or critical data manipulation scenarios.

Exploitation Status

No known exploit exists for this vulnerability at this time. The exploit maturity is assessed as none, and this CVE is not currently listed in the CISA Known Exploited Vulnerabilities catalog. This does not preclude private exploitation, but no public proof-of-concept or observed in-the-wild activity has been confirmed as of July 13, 2026.

Who Is Targeting This

No specific threat actor attribution at this time. Neither confirmed nor reported threat actor associations have been identified for this vulnerability.

What To Do

Organizations running Apache Camel deployments that use the AWS2-SQS component should treat this as a high-priority patch given the critical CVSS rating and the network-exploitable nature of the flaw. Apply the latest patched version of Apache Camel as released by the Apache Software Foundation, and consult the official Apache Camel security advisory for the specific fixed version. As an interim measure, restrict access to SQS queues consumed by Camel routes to trusted publishers only, using AWS IAM policies and SQS access control policies to limit who can send messages to monitored queues. Monitor Camel application logs for unexpected header values or processing exceptions originating from SQS message ingestion as a detection signal. Organizations with internet-facing or multi-tenant Camel deployments should prioritize remediation immediately.
