Description
NocoDB before 2026.09.0 contains an information disclosure vulnerability that allows authenticated base Viewers to obtain TLS client private keys by reading a base's data source. The source read handler masked only the connection password, letting attackers retrieve the decrypted private key, client certificate and CA to connect directly to the external database, bypassing NocoDB permissions.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
The records we use list no fixed release for CVE-2026-126271. Check the upstream advisory for a patched version, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
