8.3 highEPSS 0.2%

High (8.3) in nocodb nocodb. EPSS 0.2% estimated probability of exploitation activity in the next 30 days.

On this page
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.
