The Lemur package has a missing authorization check on the POST /certificates/<id>/export endpoint for plugins with requires_key set to False, allowing any authenticated user to export certificates they do not own.

What happened

The Lemur package is reported to have a missing authorization check on the POST /certificates/<id>/export endpoint. This vulnerability affects plugins with requires_key set to False. It allows any authenticated user to export certificates they do not own. The vulnerability was first flagged on 2026-08-18T20:51:42+00:00. It is currently under investigation and has not been exploited in the wild.

To assess your exposure, check if you are using the Lemur package in your projects. If so, verify the version you are using against the affected version ranges provided in the threat data.

What to do about it

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 lemur 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?
