Summary
An improper input validation vulnerability exists in the Apache Camel Tika component. The Tika producer mapped every metadata key parsed from the submitted document onto the Exchange as a header without filtering, allowing attacker-controlled document content to set Camel namespace headers such as CamelFileName.
Risk Assessment
A crafted document can set Exchange headers that the rest of the route depends on, including Camel headers that decide where content is written. This may lead to header injection and unexpected downstream component behavior, such as writing files to unintended locations.
Recommendation
Upgrade Apache Camel to 4.23.0, or to 4.18.5 for 4.18.x LTS or 4.22.1 for 4.22.x LTS. If immediate upgrade is not possible, strip the Camel namespace after the Tika producer with removeHeaders("Camel*") before any component that acts on those headers.
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-2026-78162Critical
A deserialization of untrusted data vulnerability in Apache Camel affects the camel-hazelcast component. Two configuration paths (ReplicatedHazelcastAggregationRepository and client mode in HazelcastDefaultComponent) fail to apply the JavaSerializationFilterConfig, allowing an attacker to achieve remote code execution by injecting a malicious Java object into the Hazelcast cluster.
- 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.
Original NVD description (English source)
Improper Input Validation vulnerability in Apache Camel Tika component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. The Tika producer mapped every metadata key parsed out of the submitted document onto the Exchange as a header, with no filter applied. Document metadata is attacker-controlled content: the party that supplies the file chooses the metadata keys it carries. A crafted document could therefore set Exchange headers that the rest of the route depends on, including headers in the Camel namespace such as CamelFileName, which downstream components use to decide where content is written. The pattern is the same header-injection class as the consumer advisories published previously, reached here through parsed file content rather than through a protocol header. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. Parsed document metadata is now filtered through a HeaderFilterStrategy before it is mapped onto the Exchange. A route that was reading a metadata-derived header the filter now blocks will see it missing. For deployments that cannot upgrade immediately, strip the Camel namespace after the Tika producer with removeHeaders("Camel*") before any component that acts on those headers.
