CVE-2026-45290
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCloudburst Network provides network components used within Cloudburst projects. A vulnerability in versions prior to `1.0.0.CR3-20260417.085727-30` impacts publicly accessible software depending on the affected versions of Network and allows an attacker to exploit a vulnerability in Network to stall the netty event loop, rendering it inoperable. All consumers of the library should upgrade to at least version `1.0.0.CR3-20260417.085727-30`. There are no known workarounds beyond updating the library.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Cloudburst Network library usageSearch project dependency files (pom.xml, build.gradle, requirements.txt) or compiled JARs for 'cloudburst-network' or 'cloudburst' artifactsAffected if The Cloudburst Network library is present as a dependency
-
Determine installed library versionExamine the resolved library version in your dependency management system, build output, or inspect the JAR file manifest/META-INF for version metadataAffected if The version is older than 1.0.0.CR3-20260417.085727-30 or cannot be determined to be that version or later
-
Verify publicly accessible Network componentReview network exposure settings, firewall rules, or service bindings to determine if the Network component listens on external interfaces (0.0.0.0 or public IP addresses)Affected if The Network component is bound to publicly reachable network interfaces
-
Check Netty event loop configurationInspect configuration files or code that initializes the Netty event loop group used by Cloudburst NetworkAffected if A custom event loop group is configured that may be vulnerable to stalling
-
Confirm application typeReview application architecture documentation or code to verify it uses the affected Network component for remote communicationsAffected if The application relies on Cloudburst Network for remote client connections
You are affected if your environment uses a version of Cloudburst Network library older than 1.0.0.CR3-20260417.085727-30 and the Network component is publicly accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade Cloudburst Network to version 1.0.0.CR3-20260417.085727-30 or later. No workarounds are available; immediate patching is required.
1.0.0.CR3-20260417.085727-30 or later
- Locate the Cloudburst Network dependency in your project's dependency management file (e.g., pom.xml, build.gradle, requirements.txt)
- Update the Cloudburst Network library version to at least 1.0.0.CR3-20260417.085727-30
- Rebuild and redeploy your application to ensure the updated library is in use
