GHSA-F5CX-H789-J959
Vulnerability from github – Published: 2025-06-19 16:19 – Updated: 2025-06-20 14:19Impact
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).

Vulnerability from github – Published: 2026-05-12 18:30 – Updated: 2026-05-15 15:30The _load_model() function in the neural_magic_training.py script of the optimate project in commit a6d302f912b481c94370811af6b11402f51d377f (2024-07-21) is vulnerable to insecure deserialization (CWE-502). When a user provides a single model file path (e.g., .pt or .pth) via the --model command-line argument, the function loads the file using torch.load() without enabling the weights_only=True security parameter. This allows the deserialization of arbitrary Python objects through the Pickle module. A remote attacker can exploit this by providing a maliciously crafted model file, leading to arbitrary code execution during deserialization on the victim's system.

Mitigation
If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
Mitigation
When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
Mitigation
Explicitly define a final object() to prevent deserialization.
Mitigation
- Make fields transient to protect them from deserialization.
- An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
Mitigation
Avoid having unnecessary types or gadgets (a sequence of instances and method invocations that can self-execute during the deserialization process, often found in libraries) available that can be leveraged for malicious ends. This limits the potential for unintended or unauthorized types and gadgets to be leveraged by the attacker. Add only acceptable classes to an allowlist. Note: new gadgets are constantly being discovered, so this alone is not a sufficient mitigation.
Mitigation
Employ cryptography of the data or code for protection. However, it's important to note that it would still be client-side security. This is risky because if the client is compromised then the security implemented on the client (the cryptography) can be bypassed.
Mitigation MIT-29
Strategy: Firewall
Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].
CAPEC-586: Object Injection
An adversary attempts to exploit an application by injecting additional, malicious content during its processing of serialized objects. Developers leverage serialization in order to convert data or state into a static, binary format for saving to disk or transferring over a network. These objects are then deserialized when needed to recover the data/state. By injecting a malformed object into a vulnerable application, an adversary can potentially compromise the application by manipulating the deserialization process. This can result in a number of unwanted outcomes, including remote code execution.
