How to Fix CVE-2026-46455

To remediate this vulnerability, upgrade all affected Apache Camel-Keycloak dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

org.apache.camel:camel-keycloak fixed: 4.18.3
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-keycloak</artifactId>
    <version>4.18.3</version>
</dependency>
org.apache.camel:camel-keycloak fixed: 4.21.0
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-keycloak</artifactId>
    <version>4.21.0</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

mvn dependency:tree -Dincludes=org.apache.camel

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-46455, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.camel

Analyze the terminal output to locate any version of Apache Camel-Keycloak in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.18.3), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.camel command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-613: Insufficient Session Expiration, where according to wasc, "insufficient session expiration is when a web site permits an attacker to reuse old session credentials or session ids for authorization.". In Apache Camel-Keycloak, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Insufficient Session Expiration vulnerability in Apache Camel Keycloak Component. The camel-keycloak security helper KeycloakSecurityHelper.parseAndVerifyAccessToken builds a Keycloak TokenVerifier using withChecks(...) with only the subject-exists check and the realm-URL (issuer) check. Keycloak's TokenVerifier.withChecks(...) appends to an initially empty check list - the upstream default checks are installed only when withDefaultChecks() is called - so the built-in IS_ACTIVE predicate, which validates the token's exp (expiration) and nbf (not-before) claims, is never applied. As a result the helper verifies the token signature, subject and issuer but does not enforce the token's validity window: an access token that is expired, or not yet valid, is accepted as valid. Routes that rely on this helper to authenticate inbound requests therefore accept access tokens that are outside their intended lifetime. This issue affects Apache Camel: from 4.18.0 before 4.18.3, from 4.19.0 before 4.21.0. Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. The fix makes KeycloakSecurityHelper.parseAndVerifyAccessToken include the TokenVerifier.IS_ACTIVE check so that expired or not-yet-valid access tokens are rejected, aligning the helper with Keycloak's default check set. For deployments that cannot upgrade immediately, enforce token expiration outside the helper - for example validate the access token's exp/nbf claims in the route before trusting it, keep Keycloak access-token lifetimes short, and ensure any upstream gateway or resource server also validates the token validity window.
