CVE-2026-108728 flyteorg CVE debrief

Who should care

Defenders responsible for Flyte deployments, especially those with Pod read access not strictly controlled, should assess exposure and prioritize remediation. This includes operators, platform administrators, and security teams who manage Flyte deployments and need to ensure the security of sensitive information. Defenders should also review the CVE record and source item to understand the affected scope, severity, and vendor guidance.

Why it matters

Defenders should care about CVE-2026-108728 because it allows users with Pod read access to obtain secrets in Flyte 2.0.1 through 2.0.51 deployments.

• Obtain secrets by reading init container environment variables
• Decode base64-encoded secret values from Pod spec

Technical summary

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. This allows users with Pod read access to obtain secrets in Flyte 2.0.1 through 2.0.51 deployments. Defenders should prioritize verifying and remediating this vulnerability in Flyte deployments, especially in environments where Pod read access is not strictly controlled. The vulnerability is caused by the lack of proper secret storage, and defenders should review the CVE record and source item for additional information.

Defensive priority

Defenders should prioritize verifying and remediating this vulnerability in Flyte deployments, especially in environments where Pod read access is not strictly controlled.

Recommended defensive actions

• Verify Flyte deployments for version 2.0.1 through 2.0.51 and assess exposure
• Restrict Pod read access to sensitive information
• Remediate vulnerable Flyte deployments by updating to a non-vulnerable version
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
