CVE-2025-47771 (GCVE-0-2025-47771)

Vulnerability from cvelistv5 – Published: 2025-06-19 23:41 – Updated: 2025-06-20 15:55

Title

PowSyBl Core allows deserialization of untrusted SparseMatrix data

Summary

PowSyBl (Power System Blocks) is a framework to build power system oriented software. In versions 6.3.0 to 6.7.1, there is a deserialization issue in the read method of the SparseMatrix class that can lead to a wide range of privilege escalations depending on the circumstances. This method takes in an InputStream and returns a SparseMatrix object. This issue has been patched in com.powsybl:powsybl-math: 6.7.2. A workaround for this issue involves not using SparseMatrix deserialization (SparseMatrix.read(...) methods).

Summary

PowSyBl Core allows deserialization of untrusted SparseMatrix data

Details

Impact

What kind of vulnerability is it? Who is impacted?

This is a disclosure for a security vulnerability in the SparseMatrix class. The vulnerability is a deserialization issue that can lead to a wide range of privilege escalations depending on the circumstances. The problematic area is the read method of the SparseMatrix class. This method takes in an InputStream and returns a SparseMatrix object. We consider this to be a method that can be exposed to untrusted input in at least two use cases: - A user can adopt this method in an application where users can submit an InputStream and the application parses it into a SparseMatrix. This can be a multi-tenant application that hosts many different users perhaps with different privilege levels. - A user adopts the method for a local tool but receives the InputStream from external sources.

Am I impacted?

You are vulnerable if you import non-controlled serialized SparseMatrix objects.

Patches

com.powsybl:powsybl-math:6.7.2 and higher

Workarounds

Is there a way for users to fix or remediate the vulnerability without upgrading?

Do not use SparseMatrix deserialization (SparseMatrix.read(...) methods).
