CVE-2026-50244
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 · uneditedThe Naxclow platform exposes a registration endpoint that accepts signed requests containing a batch prefix and an arbitrary caller-supplied account identifier, without validating any ownership relationship. Each call mints a new sequential device identifier and returns the current high-water counter value for the batch, allowing callers to measure and enumerate the active device space. The endpoint’s behavior enables precise fleet enumeration.

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 Naxclow platform installationSearch for Naxclow components in your environment: check for services named 'naxclow', look for naxclow configuration files, or search process lists for naxclow-related entriesAffected if Naxclow platform is present in the environment
-
Determine installed Naxclow versionExamine version information from naxclow service binaries, configuration files, or API responses from the platform endpoints. Compare against the affected version range provided in CVE documentationAffected if The installed version falls within the vulnerable version range
-
Verify registration endpoint accessibilityLocate and access the registration endpoint (typically /register, /api/register, or similar path). Confirm the endpoint accepts signed requests with account identifier parametersAffected if The registration endpoint is accessible and accepts account identifier parameters without ownership validation
-
Test for arbitrary account identifier acceptanceSubmit a signed registration request with a caller-supplied account identifier for a different account than the caller owns. Observe if the request succeeds and returns device identifiers or counter valuesAffected if The endpoint accepts and processes requests with arbitrary account identifiers without verifying the caller owns the specified account
-
Check batch counter exposureAttempt to retrieve high-water counter values or sequential counter information for batches belonging to accounts the caller does not ownAffected if Counter values for arbitrary batches are accessible to unauthorized callers
A user is affected if the Naxclow platform is deployed and its registration endpoint allows signed requests with caller-supplied account identifiers without ownership validation, exposing device identifiers and batch counters for accounts the caller does not own.

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 ownership validation to ensure callers can only register devices for accounts they own, and restrict access to batch counter information to authorized users.
