How to Fix CVE-2026-8088

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: 3.13.0 
pip install GDAL>=3.13.0
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 GDAL

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-8088, 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 3.13.0), 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-119: Improper Restriction of Operations within the Bounds of a Memory Buffer, where the product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. this may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. 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 weakness has been identified in OSGeo gdal up to 3.13.0dev-4. The affected element is the function GDfieldinfo of the file frmts/hdf4/hdf-eos/GDapi.c. Executing a manipulation can lead to out-of-bounds read. The attack needs to be launched locally. The exploit has been made available to the public and could be used for attacks. Upgrading to version 3.13.0RC1 is sufficient to fix this issue. This patch is called a791f70f8eaec540974ec989ca6fb00266b7646c. The affected component should be upgraded.
