Vanna: Code injection in VannaBase.get_plotly_figure
Summary
Vanna v2.0.2 contains a code injection flaw in the legacy function VannaBase.get_plotly_figure. Depending on the exposed entry point, an attacker can run attacker-controlled code or commands on the host running Vanna. Exploitation is network-reachable and rated as low complexity, and CISA SSVC lists a proof of concept as existing; the official record lists no authentication requirement, but this depends on how the application exposes Vanna.
Affected
- Vanna v2.0.2 (named in the CVE record)
- Other 2.x releases: Unknown.
Fixed in
- Unknown. No vendor advisory or patched version has been confirmed.
Workaround
- Do not expose Vanna endpoints to the internet; place them behind authentication, SSO or a VPN.
- Do not use the legacy get_plotly_figure path or chart generation with untrusted input.
- Run the service in a container with minimal privileges and without access to secrets.
- Monitor for unexpected child processes spawned by the Python service.
Exploitation
- CISA SSVC: exploitation status 'poc', automatable 'yes', technical impact 'total'.
- Not listed in CISA KEV. No confirmed in-the-wild exploitation.
- A public proof of concept may exist; VulDB states no exploit exists, so the status is conflicting and unverified.
Our recommendation
- Inventory all Vanna deployments and check for version 2.0.2 (pip show vanna).
- Verify whether the web endpoints are internet-facing and whether they require authentication.
- Restrict access via VPN, SSO or IP allow-listing and disable chart features where not needed.
- Watch the vendor GitHub repository and NVD for a patched release and verify the installed version after patching.
