nocodb: Insufficiently Protected Credentials
CVE-2026-126271 is a high-severity insufficiently protected credentials vulnerability in nocodb, with a CVSS 3.1 base score of 7.7 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 2026.09.0 as the first without the flaw, so updating nocodb to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.23% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do

Official 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.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Insufficiently Protected Credentials
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
How developers prevent this class of flaw
- Use an appropriate security mechanism to protect the credentials.
- Make appropriate use of cryptography to protect the credentials.
- Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
