Flyte 2.0.1 through 2.0.51 contains a cleartext secret storage vulnerability that allows users with Pod read access to obtain secrets by reading init container environment variables.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.23%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Flyte 2.0.1 through 2.0.51 contains a cleartext secret storage vulnerability that allows users with Pod read access to obtain secrets by reading init container environment variables. The embedded secret manager webhook writes base64-encoded FILE-mounted secret values into the SECRETS environment variable, letting principals without Secret store access decode them from the Pod spec.
