CVE-2026-6272Public exploitNetwork attack vector

Signal data forgery via unchecked provider registration

Published Apr 24, 2026 · Updated Apr 24, 2026

Authorization bypass in Eclipse KUKSA Databroker 0.5.0 through 0.6.0 allows remote authenticated users to forge returned signal data. AuthorizedAccess register_signals and extend_signals accept ProvideSignalRequest without checking can_write_datapoint for the requested signal. A valid read-scoped JWT and network access to kuksa.val.v2 are sufficient to register a provider and supply forged values to GetValue or GetValues callers.
