Low risk33th percentile - higher than 33% of all known CVEs
Summary
The camel-keycloak component in Apache Camel lacks validation of the access token's validity window. The helper function does not check whether the token is expired or not yet valid, accepting tokens outside their intended lifetime.
Risk Assessment
The organization is at risk of accepting expired or premature access tokens, which could lead to unauthorized access to protected resources and compromise system integrity.
Recommendation
Upgrade Apache Camel to version 4.21.0 (or 4.18.3 for the 4.18.x branch) immediately. If an upgrade is not possible, manually validate the token's exp and nbf claims in routes and keep access token lifetimes short.
Other vulnerabilities in Apache Camel
See all- CVE-2015-5348High
Apache Camel versions 2.6.x through 2.14.x, 2.15.x before 2.15.5, and 2.16.x before 2.16.1, when using camel-jetty or camel-servlet as consumers in Camel routes, allow remote attackers to execute arbitrary commands via a crafted serialized Java object in an HTTP request.
- CVE-2014-0002High
The XSLT component in Apache Camel before 2.11.4 and 2.12.x before 2.12.3 allows remote attackers to read arbitrary files and possibly have other unspecified impact via an XML document containing an external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.
- CVE-2026-71300Critical
Vulnerability in Apache Camel Atmosphere Websocket component due to improper input validation of Exchange headers outside the Camel namespace (websocket.connectionKey, websocket.connectionKey.list, websocket.sendToAll, websocket.eventType, websocket.errorType). An external attacker can supply the list header via HTTP and take over the producer's dispatch decision, potentially suppressing or redirecting notifications to a different client.
- CVE-2026-66906Critical
Relative path traversal vulnerability in Apache Camel Azure Storage Blob component allows writing files outside the configured directory during downloadBlobToFile operation. Blob names with parent-directory segments are not normalized, enabling overwriting arbitrary files with Camel process privileges.
- CVE-2026-56140Critical
The Apache Camel AWS SNS component lacks an inbound filter rule in the Sns2HeaderFilterStrategy. However, the vulnerability is not exploitable because the component is producer-only (does not support consumers), so an attacker cannot supply external message attributes to the Camel Exchange. A defense-in-depth filter was added for consistency with other strategies.
- CVE-2026-53913Critical
A vulnerability in the camel-keycloak component of Apache Camel allows bypassing access token verification in the default configuration. When required roles or permissions are empty, the token is not cryptographically verified, allowing access to protected routes with any Authorization header.
- CVE-2026-48205Critical
A vulnerability in the Apache Camel DNS component allows SSRF attacks via improper input validation of message headers. An attacker can set dns.server, dns.name, and dns.domain headers in an HTTP request, redirecting DNS queries to a controlled server and disclosing internal hostnames.
- CVE-2026-48204Critical
Vulnerability in Apache Camel's mongodb-gridfs component allows an attacker to manipulate GridFS operations via HTTP headers. Improper input validation and access control enable unauthorized file deletion, reading, enumeration, and NoSQL operator injection.
- CVE-2026-48203Critical
Vulnerability in Apache Camel Solr component allows SSRF and injection of Solr parameters and fields. Exchange headers with SolrParam. and SolrField. prefixes are passed unfiltered from HTTP requests to the Solr producer, enabling attackers to manipulate queries and indexed documents.
- CVE-2026-46456Critical
Vulnerability in Apache Camel AWS2-SQS component allows attackers to inject Camel control headers (e.g., CamelHttpUri, CamelFileName) via SQS messages. Missing inbound filtering in Sqs2HeaderFilterStrategy enables modification of downstream producer behavior in the route.
Original NVD description (English source)
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.
