How to Fix CVE-2026-46645

To remediate this vulnerability, upgrade all affected SQLAdmin dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

sqladmin fixed: 0.25.1 
pip install sqladmin>=0.25.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show sqladmin

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-46645, inspect your installed packages using pip:

pip show sqladmin

Analyze the terminal output to locate any version of SQLAdmin in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.25.1), your application is affected.

Note: The pip show sqladmin command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. In SQLAdmin, 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.

Source Advisory Statement

### Impact The `ajax_lookup` endpoint in `application.py` bypasses the `is_accessible()` access control check that all other endpoints enforce. If a developer restricts model access by overriding `is_accessible()`, an authenticated user can still query that model's data through the `ajax_lookup` endpoint — silently bypassing the restriction. **Affected endpoint:** `GET /{identity}/ajax/lookup?name=<field>&term=<query>` **All other endpoints enforce both checks:** | Endpoint | `@login_required` | `is_accessible()` | |---|---|---| | `list` | ✓ | ✓ | | `create` | ✓ | ✓ | | `edit` | ✓ | ✓ | | `delete` | ✓ | ✓ | | `details` | ✓ | ✓ | | `export` | ✓ | ✓ | | `ajax_lookup` (before fix) | ✗ | ✗ | | `ajax_lookup` (after fix) | ✓ | ✓ | Note: before this fix, `ajax_lookup` also lacked the `@login_required` decorator — unauthenticated users could query it directly. That was addressed in #1035. This report covers the remaining gap: authenticated but unauthorized users. ### Patches Two changes were made to `ajax_lookup`: 1. Replaced the hand-rolled authentication check added in #1035 with the standard `@login_required` decorator used by all other endpoints. 2. Added the missing `is_accessible(request)` check, raising `HTTP 403` when it returns `False`. ### Workarounds None. Developers relying on `is_accessible()` to restrict model visibility are exposed regardless of what other access controls are in place.
