Title
Apache Camel: Camel-Knative Improper Certificate Validation When SSL Is Enabled Without a Truststore
Summary
Improper Certificate Validation vulnerability in Apache Camel Knative component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. When SSL was enabled on the Knative HTTP client but no truststore was configured, the client options fell back to trusting every presented certificate rather than to the JVM's default trust anchors. A deployment that switched TLS on without also configuring a truststore therefore obtained an encrypted connection with no peer authentication, which an attacker positioned on the network path can terminate and read. The dangerous state is reached by omission rather than by an explicit opt-in, which is what makes it a framework defect: turning TLS on should not be the thing that turns certificate validation off. 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. With no truststore configured the trust options are now left unset so the JVM default trust anchors apply, the same fallback SSLContextParameters and the rest of Camel use. Trusting every certificate is now reached only by asking for it explicitly through the trust.all property, which remains available for development against a cluster with a self-signed certificate. For deployments that cannot upgrade immediately, configure a truststore explicitly wherever SSL is enabled. After upgrading, a deployment that was relying on the implicit trust-all behaviour must either configure a truststore or set the trust.all property deliberately.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
