MODERATECVE-2025-49142 is a MODERATE nautobot vulnerable to secrets exposure vulnerability (CWE-1336: Improper Neutralization of Special Elements Used in a Template Engine) affecting Nautobot libraries in the PyPI ecosystem. The issue involves nautobot vulnerable to secrets exposure and data manipulation through jinja2 templating. Remediation is available by upgrading affected packages to version 1.6.32, 2.4.10.
CVE-2025-49142 at a Glance
How to Fix CVE-2025-49142
To remediate this vulnerability, upgrade all affected Nautobot dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
pip install nautobot>=1.6.32
pip install nautobot>=2.4.10
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
pip show nautobot
How to Check if You Are Affected
To determine whether your Python environment is affected by CVE-2025-49142, inspect your installed packages using pip:
pip show nautobot
Analyze the terminal output to locate any version of Nautobot in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.6.32), your application is affected.
Note: The pip show nautobot command checks currently installed packages in your active Python environment.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-1336: Improper Neutralization of Special Elements Used in a Template Engine, where the product uses a template engine to insert or process externally-influenced input, but it does not neutralize or incorrectly neutralizes special elements or syntax that can be interpreted as template expressions or other code directives when processed by the engine. In Nautobot, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Impact\n_What kind of vulnerability is it? Who is impacted?_\n\nAll users of Nautobot versions prior to 2.4.10 or prior to 1.6.32 are potentially affected.\n\nDue to insufficient security configuration of the Jinja2 templating feature used in computed fields, custom links, etc. in Nautobot:\n\n1. A malicious user could configure this feature set in ways that could expose the value of Secrets defined in Nautobot when the templated content is rendered.\n2. A malicious user could configure this feature set in ways that could call Python APIs to modify data within Nautobot when the templated content is rendered, bypassing the object permissions assigned to the viewing user.\n\n### Patches\n_Has the problem been patched? What versions should users upgrade to?_\n\nNautobot versions 1.6.32 and 2.4.10 will include fixes for the vulnerability.\n\n### Workarounds\n_Is there a way for users to fix or remediate the vulnerability without upgrading?_\n\nThe vulnerability can be partially mitigated by configuring object permissions appropriately to limit the below actions to only trusted users:\n\n- `extras.add_secret`\n- `extras.change_secret`\n- `extras.view_secret`\n- `extras.add_computedfield`\n- `extras.change_computedfield`\n- `extras.add_customlink`\n- `extras.change_customlink`\n- `extras.add_jobbutton`\n- `extras.change_jobbutton`\n\n### References\n_Are there any links users can visit to find out more?_\n\n- https://jinja.palletsprojects.com/en/stable/sandbox/\n- https://docs.djangoproject.com/en/4.2/ref/templates/api/#alters-data-description\n- https://github.com/nautobot/nautobot/pull/7417\n- https://github.com/nautobot/nautobot/pull/7429",
