Nautobot is a Network Source of Truth and Network Automation Platform. All users of Nautobot versions earlier than 1.5.7 are impacted by a remote code execution vulnerability. Nautobot did not properly sandbox Jinja2 template rendering. In Nautobot 1.5.7 has enabled sandboxed environments for the Jinja2 template engine used internally for template rendering for the following objects: `extras.ComputedField`, `extras.CustomLink`, `extras.ExportTemplate`, `extras.Secret`, `extras.Webhook`. While no active exploits of this vulnerability are known this change has been made as a preventative measure to protect against any potential remote code execution attacks utilizing maliciously crafted template code. This change forces the Jinja2 template engine to use a `SandboxedEnvironment` on all new installations of Nautobot. This addresses any potential unsafe code execution everywhere the helper function `nautobot.utilities.utils.render_jinja2` is called. Additionally, the documentation that had previously suggesting the direct use of `jinja2.Template` has been revised to suggest `render_jinja2`. Users are advised to upgrade to Nautobot 1.5.7 or newer. For users that are unable to upgrade to the latest release of Nautobot, you may add the following setting to your `nautobot_config.py` to apply the sandbox environment enforcement: `TEMPLATES[1]["OPTIONS"]["environment"] = "jinja2.sandbox.SandboxedEnvironment"` After applying this change, you must restart all Nautobot services, including…

GHSA-8mfq-f5wj-vw5m — Nautobot vulnerable to remote code execution via Jinja2 template rendering

2026-10-23T22:37:53.871574+00:00

Affected: PyPI: nautobot

### Impact _What kind of vulnerability is it? Who is impacted?_

All users of Nautobot versions earlier than 1.5.7 are impacted.

In Nautobot 1.5.7 we have enabled sandboxed environments for the Jinja2 template engine used internally for template rendering for the following objects:

- `extras.ComputedField` - `extras.CustomLink` - `extras.ExportTemplate` - `extras.Secret` - `extras.Webhook`

While we are not aware of any active exploits, we have made this change as a preventative measure to protect against any potential remote code execution attacks utilizing maliciously crafted template code.

This change forces the Jinja2 template engine to use a [`SandboxedEnvironment`](https://jinja.palletsprojects.com/en/3.0.x/sandbox/#sandbox) on all new installations of Nautobot.

This addresses any potential unsafe code execution everywhere the helper function `nautobot.utilities.utils.render_jinja2` is called. Additionally, our documentation that was previously suggesting the direct use of `jinja2.Template` has been revised to utilize `render_jinja2`.

### Patches _Has the problem been patched? What versions should users upgrade to?_

Yes. Users should upgrade to Nautobot 1.5.7 or newer.

### Workarounds _Is there a way for users to fix or remediate the vulnerability without upgrading?_

##### Enabling Sandboxed Environments

For users that are unable to upgrade to the latest release of Nautobot, you may add the following setting to your `nautobot_config.py` to apply the sandbox e…
