How to Fix CVE-2026-62282

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

opencve fixed: 3.0.0 
pip install opencve>=3.0.0
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 opencve

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-62282, inspect your installed packages using pip:

pip show opencve

Analyze the terminal output to locate any version of OpenCVE in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.0), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In OpenCVE, 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 OpenCVE contains a Server-Side Request Forgery (SSRF) vulnerability in the notification testing functionality for both Webhook and Slack integrations. An authenticated user with permission to configure notification channels can trigger test requests to arbitrary HTTP(S) endpoints. Insufficient validation of target destinations allows requests to be sent to hosts reachable from the OpenCVE server, including internal network resources, localhost interfaces, and cloud metadata services. Successful exploitation could allow an attacker to interact with internal services that are not otherwise accessible from the Internet and retrieve information from HTTP-based services reachable by the OpenCVE instance. ### Patches The vulnerability has been fixed in OpenCVE version 3.0.0, users should upgrade to version 3.0.0 or later. The fix introduces additional validation of user-supplied URLs used by the notification testing functionality and prevents requests to localhost, private network ranges, link-local addresses, cloud metadata services, and other non-public destinations. ### Workarounds Users unable to upgrade should restrict outbound network access from OpenCVE to trusted external destinations using firewall rules, network policies, or egress filtering. Where possible, access to localhost interfaces, private network ranges, and cloud metadata services should be blocked from the OpenCVE application environment. Disabling access to the notification testing functionality also mitigates the issue.
