CVE-2026-33454

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
