CVE-2026-18948
An early warning has been issued for a critical vulnerability in the Feast package. The flaw allows for unauthenticated arbitrary code execution on the feature server in default configurations.
What happened
A flaw was found in Feast, where the system improperly deserializes user-defined functions (UDFs) stored in its registry, which are serialized using the 'dill' library. This allows a remote attacker to store a malicious UDF, leading to unauthenticated arbitrary code execution on the feature server in default configurations. The vulnerability is tracked as CVE-2026-18948 with a CVSS score of 9.9.
To assess your exposure, check if you are using an affected version of Feast. The vulnerability affects versions less than 0.54.0 and various other specific version ranges as detailed in the threat data.
What to do about it
- Upgrade to the latest version of Feast to mitigate the risk of this vulnerability.
- Review the registry server's authorization checks to prevent arbitrary code execution.
- Monitor the primary sources for updates on this vulnerability and any official fixes that may be released.
How 0Day would have caught this
MATCHED TO YOUR ACTUAL DEPENDENCY GRAPH0Day matches every incoming threat signal against your GitHub organization’s full dependency graph, including transitive dependencies. If
feast is anywhere in your dependency tree, the engineers who own the affected repositories get a push alert the moment it is flagged — no manual audit to remember to run.Read how this differs from waiting on a scanner to catch a known advisory, or see the exact, read-only access 0Day needs to do this for an organization.
Frequently asked questions
Am I affected?
You are affected if you are using Feast version less than 0.54.0 or any of the other specific version ranges listed in the threat data.
What should I do right now?
Upgrade to the latest version of Feast and review the registry server's authorization checks to prevent arbitrary code execution.
Is there an official fix available?
No official fix has been published yet. Monitor the sources for updates.
