How to Fix CVE-2026-47157

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

aiograpi fixed: 0.9.10 
pip install aiograpi>=0.9.10
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 aiograpi

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-47157, inspect your installed packages using pip:

pip show aiograpi

Analyze the terminal output to locate any version of aiograpi in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.9.10), your application is affected.

Note: The pip show aiograpi 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 aiograpi, 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

aiograpi versions before 0.9.10 accepted server-supplied signup challenge paths and used them to build request URLs before validating that the paths were relative Instagram API paths. A malicious or tampered challenge payload could cause challenge handling requests to be sent outside the intended Instagram host with the client\'s existing session headers. Version 0.9.10 validates challenge paths before building URLs, solving captcha challenges, or submitting phone/SMS challenge forms.
