Heap-based Buffer Overflow Affecting nvidia-pytriton package, versions [0,]
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

CVE-2025-23317 (opens in a new tab)How to fix?
There is no fixed version for nvidia-pytriton.
Overview
nvidia-pytriton is a PyTriton - Flask/FastAPI-like interface to simplify Triton's deployment in Python environments.
Affected versions of this package are vulnerable to Heap-based Buffer Overflow through the HTTP/Sagemaker request handler components when parsing chunked HTTP bodies. An attacker can execute arbitrary code by sending a specially crafted chunked request with an excessive number of chunks to trigger a stack overflow in those handlers.
Note: This vulnerability is only exploitable when using the default bundled Python backend /pytriton/tritonserver/backends/python/libtriton_python.so.
Workaround
It is possible to update the Python backend to a patched version independently of PyTriton; See Triton Inference Server Backend and Building binaries from source.
