Summary

lakeFS is Missing Timestamp Validation in S3 Gateway Authentication

Details

Impact

LakeFS's S3 gateway does not validate timestamps in authenticated requests, allowing replay attacks. An attacker who captures a valid signed request (e.g., through network interception, logs, or compromised systems) can replay that request until credentials are rotated, even after the request is intended to expire.

Patches

This issue affects all versions of lakeFS up to and including v1.74.4.

The vulnerability has been fixed in version v1.75.0.

Users should upgrade to version v1.75.0.

Workarounds

Until upgraded, implement these mitigations:

Use short-lived credentials - Rotate access keys frequently and deactivate old keys. For regular requests, captured requests only work until rotation. For presigned URLs, they remain valid until the credentials used to create them are deactivated.
Network controls - Restrict S3 gateway access to trusted networks/IPs to limit where replay attacks can originate.

Note: These workarounds reduce risk but do not fully eliminate the vulnerability.
