What is CVE-2025-27636?

CVE-2025-27636 is a vulnerability found in the Apache Camel framework, specifically affecting its Camel-Bean component under certain configurations. Apache Camel is widely used for integrating different applications using various protocols and formats, facilitating data routing and transformation. The identified vulnerability enables attackers to potentially bypass security mechanisms, which could lead to unauthorized method invocations within a bean component. This poses a significant risk for organizations relying on Apache Camel for critical integrations, as it could compromise the integrity and confidentiality of applications utilizing vulnerable configurations.

Technical Details

This vulnerability affects Apache Camel versions from 4.10.0 to 4.10.1, 4.8.0 to 4.8.4, and 3.10.0 to 3.22.3. The flaw is triggered when specific Camel components, such as camel-servlet, camel-jetty, camel-undertow, camel-platform-http, or camel-netty-http, route exchanges to a Camel-Bean producer. An attacker can take advantage of the insufficient filtering mechanism that currently only blocks HTTP headers starting with "Camel", "camel", or "org.apache.camel.". When conditions are met, this allows them to forge Camel header names, invoking unwanted methods from the same bean, leading to potential unauthorized operations.

Potential Impact of CVE-2025-27636

Unauthorized Access to Bean Methods: The most immediate risk is that an attacker could exploit the flaw to invoke methods on a bean that should not be accessible, potentially leading to unauthorized access to sensitive functionalities or data.
Data Integrity Threats: If attackers can manipulate method calls on a bean, they may alter business logic or data inadvertently, resulting in data corruption or integrity violations within applications that depend on accurate processing.
Increased Attack Surface for Exploitation: The conditions that allow this vulnerability to manifest increase the overall attack surface, making systems more susceptible to further exploits or attacks, particularly if the initial method invocations are leveraged to gain additional access or control over the application environment.
