How to Fix CVE-2026-8212

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

GDAL fixed: 3.13.0RC1 
pip install GDAL>=3.13.0RC1
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 GDAL

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-8212, inspect your installed packages using pip:

pip show GDAL

Analyze the terminal output to locate any version of GDAL in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.13.0RC1), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-125: Out-of-bounds Read, where the product reads data past the end, or before the beginning, of the intended buffer. In GDAL, 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

A flaw has been found in OSGeo gdal up to 3.13.0dev-4. Affected by this vulnerability is the function SWSDfldsrch of the file frmts/hdf4/hdf-eos/SWapi.c. Executing a manipulation can lead to heap-based buffer overflow. The attack requires local access. The exploit has been published and may be used. Upgrading to version 3.13.0RC1 addresses this issue. This patch commit sha is 3e04c0385630e4d42517046d9a4967dfccfeb7fd. The affected component should be upgraded.
