DescriptionCVE.org

Improper Input Validation vulnerability in Apache Camel.

This issue affects Apache Camel: from 4.8.0 through 4.18.2, from 4.19.0 through 4.20.0.

Users are recommended to upgrade to version 4.18.3, 4.21.0, which fixes the issue.

AnalysisAI

Improper input validation in Apache Camel versions 4.8.0 through 4.18.2 and 4.19.0 through 4.20.0 allows remote unauthenticated attackers to send crafted input that the framework fails to validate, yielding limited information disclosure and partial integrity/availability impact per the CVSS vector. The flaw is reported directly by the Apache Software Foundation and is fixed in 4.18.3 and 4.21.0; there is no public exploit identified at time of analysis and it is not on the CISA KEV list. The moderate 7.3 (High) score reflects easy network reachability but limited per-impact severity (C:L/I:L/A:L).

Technical ContextAI

Apache Camel is a widely deployed open-source Java integration framework implementing Enterprise Integration Patterns, used to route and mediate messages between systems via hundreds of components and endpoints. The root cause is classified as CWE-20 (Improper Input Validation), meaning the framework accepts externally supplied input without adequately verifying that it conforms to expected structure, type, or constraints before processing it. The affected artifact is identified by CPE cpe:2.3:a:apache_software_foundation:apache_camel and, per the vendor tag, the practical consequence is Information Disclosure. Because Camel typically sits at trust boundaries between services, an input-validation gap in a component or header/parameter handling path can expose or alter data flowing through a route, though the exact vulnerable component is not detailed in the available advisory summary.

RemediationAI

Vendor-released patch: upgrade to Apache Camel 4.18.3 (for the 4.8.0-4.18.2 branch) or 4.21.0 (for the 4.19.0-4.20.0 branch), as recommended by the Apache advisory at https://camel.apache.org/security/CVE-2026-49042.html. Because the specific vulnerable component is not disclosed in the available summary, review that advisory to identify whether a particular Camel component, endpoint, or route is implicated and, if immediate patching is not possible, restrict or disable exposure of that route and place untrusted-facing Camel endpoints behind an authenticating gateway or input-filtering proxy that enforces strict schema/type validation on incoming messages - noting this may reject some legitimately malformed-but-tolerated traffic and requires knowledge of the exact affected input path. Given only Low impact metrics, upgrading during the normal maintenance window is a reasonable priority absent evidence of exploitation, but should be expedited for internet-exposed integrations.
