Summary
An incorrect default permissions vulnerability exists in the Apache Camel PQC component. When writing generated key material to disk, the component used the process default umask rather than restricting the file to its owner, potentially allowing other local accounts to read the private key.
Risk Assessment
If the umask allows group or world read, the private key may be exposed to a local party. Possession of the private key defeats every signature and key exchange performed by the deployment, which is a severe consequence despite the low severity rating.
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, place the key directory on a path only the service account can traverse, tighten the process umask, and treat already written keys as exposed and rotate them.
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)
Incorrect Default Permissions vulnerability in Apache Camel PQC component. This issue affects Apache Camel: from 4.12.0 before 4.18.5, from 4.19.0 before 4.22.1. When the component wrote generated key material to disk it did so with the permissions the process default umask produced, rather than restricting the file to its owner. On a host whose umask allows group or world read, the private key was therefore readable by other local accounts. The exposure is to a local party rather than to the remote sender that the Camel threat model treats as the primary adversary, which is why the severity is assessed low, but the consequence where it applies is complete: possession of the private key defeats every signature and key exchange the deployment performs with it. 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. Key material is now written with owner-only permissions. For deployments that cannot upgrade immediately, place the key directory on a path only the service account can traverse, and tighten the process umask. Key material already written with permissive permissions should be treated as exposed and rotated.
