CVE-2026-12588
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 · uneditedAn attacker with access to an HX 10.0.0 and previous versions, may send specially-crafted data to the HX console. The malicious detection would then trigger decompression of a large file that consumes an excessive amount of system resources thus causing a Denial of Service.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceAn attacker with console access to HX 10.0.0 and prior versions can send specially-crafted data that triggers the malicious detection mechanism. This causes the system to decompress an excessively large file, consuming disproportionate system resources and resulting in denial of service.

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 HX version installedRun the command to display the HX system version (typically via CLI with 'hx version' or checking system info panel)Affected if Version is 10.0.0 or any prior version (anything before the fixed release)
-
Verify console access configurationCheck console service settings via admin interface or config file - determine if remote console or local console ports are exposed and accessibleAffected if Console access is enabled and reachable by untrusted users
-
Locate the malicious detection mechanismSearch system configuration for detection/inspection modules that process incoming console data - look for file scanning, malware detection, or archive inspection featuresAffected if A detection/inspection feature that processes console-received data is enabled
-
Inspect decompression resource limitsReview configuration files or system settings for decompression-related parameters such as max decompress size, memory limits, or timeout valuesAffected if No resource limits are configured for decompression operations, or limits are set excessively high
-
Check for resource monitoring on decompressionExamine if there are any quotas, rate limits, or throttling configured on the detection mechanism that would constrain resource usageAffected if No rate limiting, throttling, or resource quotas are applied to the detection mechanism
You are affected if your HX version is 10.0.0 or prior, console access is available to untrusted parties, and the detection mechanism that processes console data lacks resource limits on decompression operations.

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.
From vendor dataImplement resource limits on decompression operations, add input validation on console-received data, and consider rate limiting or throttling on the detection mechanism to prevent resource exhaustion.
