Threats affecting pkg:maven/Apache Software Foundation/org.apache.camel:camel-aws2-s3

CVE-2026-95664 is an Expression Language Injection vulnerability in the Apache Camel AWS2-s3 component affecting versions from 4.8.0 before 4.18.5 and from 4.19.0 before 4.22.2. The issue arises because the key used by the aws2-s3 producer is taken from a message header and evaluated as a Simple language expression if it contains certain markers, allowing untrusted input to be executed. This can lead to unauthorized access to JVM system properties, environment variables, and invocation of methods on beans, potentially exposing sensitive information. The vulnerability is fixed in versions 4.18.5 and 4.22.2. Users are advised to upgrade to these versions or 4.23.0 or later. Workarounds include removing or validating the CamelAwsS3Key header to prevent untrusted expressions from being evaluated.
