PYSEC-2026-3043 PyTorch Lightning load_from_checkpoint has an insecure checkpoint deserialization
PyTorch-Lightning versions 2.6.0 and earlier contain an insecure deserialization vulnerability CWE-502 in the checkpoint loading mechanism. The LightningModule.loadfromcheckpoint method, which is commonly used to load saved model states, internally calls torch.load without setting the...
PYSEC-2026-1857 PyTorch Lightning denial of service vulnerability
A vulnerability in lightning-ai/pytorch-lightning version 2.3.2 allows an attacker to cause a denial of service by sending an unexpected POST request to the /api/v1/state endpoint of LightningApp. This issue occurs due to improper handling of unexpected state values, which results in the server...
PYSEC-2026-508 Compromise of PyTorch Lightning PyPi Package Versions
Security Advisory: Compromise of PyTorch Lightning PyPI Package Versions Published: 2026-04-30 Last Updated: 2026-05-12 Github Advisory: CVE-2026-44484 We have identified a security incident affecting certain versions of one of our PyPI packages. What happened We have determined that one or more...
PYSEC-2026-386 pytorch-lightning vulnerable to Arbitrary File Write via /v1/runs API endpoint
A vulnerability in the /v1/runs API endpoint of lightning-ai/pytorch-lightning v2.2.4 allows attackers to exploit path traversal when extracting tar.gz files. When the LightningApp is running with the pluginserver, attackers can deploy malicious tar.gz plugins that embed arbitrary files with path...
PYSEC-2026-385 Remote code execution in pytorch lightning
A remote code execution RCE vulnerability exists in the lightning-ai/pytorch-lightning library version 2.2.1 due to improper handling of deserialized user input and mismanagement of dunder attributes by the deepdiff library. The library uses deepdiff.Delta objects to modify application state base...
PYSEC-2026-507 PyTorch Lightning path traversal vulnerability
In lightning-ai/pytorch-lightning version 2.3.2, a vulnerability exists in the LightningApp when running on a Windows host. The vulnerability occurs at the /api/v1/uploadfile/ endpoint, allowing an attacker to write or overwrite arbitrary files by providing a crafted filename. This can lead to...
LNTest: A Testbed for Evaluating Bitcoin Lightning Network-Based Botnets
Bitcoin's Lightning Network LN can be exploited as a covert, low-cost command-and-control C&C channel for botnets, as demonstrated by the LNBot and D-LNBot designs. However, both remain proof-of-concept prototypes evaluated only through simulation, leaving key questions about real-world topology...
