Which packages are affected by CVE-2024-23345?

CVE-2024-23345 affects the following packages: nautobot (PyPI), nautobot (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2024-23345?

Update nautobot to 2.1.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-23345 is resolved across your whole dependency graph.

How do I detect CVE-2024-23345 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nautobot, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2024-23345 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
