Critical [CVE-2026-46456 +1] Improper Input Validation vulnerability in Apache Camel AWS SNS component
CVE-2026-56140Source published Jul 6, 2026Source updated Jul 9, 2026
This bulletin covers 2 CVEs. The products, versions, score and guidance below describe the bulletin; check its source for applicability to this specific CVE.
Improper Input Validation vulnerability in Apache Camel AWS SNS component. The camel-aws2-sns component filters Camel headers through a component-specific HeaderFilterStrategy, Sns2HeaderFilterStrategy. Like the sibling Sqs2HeaderFilterStrategy, it originally configured only an outbound filter (setOutFilterPattern, which blocks Camel*, breadcrumbId and org.apache.camel.* headers from being written out) and did not configure an inbound filter rule. As part of the same fix (CAMEL-23506), an inbound filter rule (setInFilterStartsWith for the Camel namespace) was added to Sns2HeaderFilterStrategy so that its configuration matches the corrected Sqs2HeaderFilterStrategy and the other sibling strategies. This is a defense-in-depth alignment with no known exploit path in camel-aws2-sns. This…

Mitigation guidance
Like the sibling Sqs2HeaderFilterStrategy, it originally configured only an outbound filter (setOutFilterPattern, which blocks Camel*, breadcrumbId and org.apache.camel.* headers from being written out) and did not configure an inbound filter rule.
Users who want the aligned behaviour can upgrade to version 4.21.0, or to 4.14.8 on the 4.14.x LTS releases stream, or to 4.18.3 on the 4.18.x releases stream, which contain the change.
As a general best practice, operators should continue to apply least-privilege IAM permissions on their SNS topics.
