CVE-2026-54559

PocketSphinx (a lightweight speech recognizer, including its Python bindings) versions 5prealpha through 5.1.0 are affected by buffer overflow vulnerabilities in its model-loading code. The trie language-model loaders in src/lm/ngram_model_trie.c fail to validate boundary conditions in ARPA, DMP,...

CVE-2026-55832 Tract: Arbitrary file read via unsanitized ONNX external_data `location` (path traversal) on model load in tract-onnx

Tract is a tiny, no-nonsense, self-contained TensorFlow and ONNX inference toolkit. Prior to 0.21.17, 0.22.3, and 0.23.2, the tract-onnx crate passes the attacker-controlled externaldata location from an ONNX model through onnx/src/tensor.rs getexternalresources and joins the value to the model...

CVE-2026-90553

A flaw was found in vLLM. The LlavaOnevision2 processor loader incorrectly ignores the trustremotecode parameter, which is designed to prevent the execution of untrusted code. This oversight allows an attacker to craft a malicious model containing arbitrary code. When such a model is loaded, the...

CVE-2026-90553

vLLM before 0.28.0 contains a remote code execution vulnerability in the LlavaOnevision2 processor loader . The loader ignores the trust_remote_code parameter when loading remote processor classes, allowing an attacker to craft a malicious model with arbitrary code in processing_llava_onevision2....

CVE-2026-90553 vLLM before 0.28.0 Remote Code Execution via LlavaOnevision2 processor

vLLM before 0.28.0 contains a remote code execution vulnerability in the LlavaOnevision2 processor loader that ignores the trustremotecode parameter when loading remote processor classes. Attackers can craft a malicious model with arbitrary code in processingllavaonevision2.py that executes with...

CVE-2026-88054

A flaw was found in Tesseract, an open-source Optical Character Recognition OCR engine. A remote attacker could provide a specially crafted '.traineddata' model with a zero-length stack for certain internal layers. This would cause an empty-stack dereference during model loading, leading to a...

CVE-2026-88054

Tesseract is an open-source OCR engine affected in version 5.5.3 and earlier by a denial-of-service flaw. The root cause is in Plumbing::DeSerialize (src/lstm/plumbing.cpp), which rejects excessively large network stacks but accepts a zero-length stack for NT_SERIES, NT_PARALLEL, or NT_REVERSED l...

PYSEC-2026-3856 Keras model loading is vulnerable to denial of service through HDF5 shape bombs

A vulnerability in keras-team/keras versions 3.15.0 allows for a denial of service DoS attack when loading malicious .keras model files via the keras.models.loadmodel function. The H5IOStore.getitem method in keras/src/saving/savinglib.py does not validate the shape or size of datasets, leading t...

CVE-2026-86169

Axolotl before 0.19.0 contains a remote code execution vulnerability in the multipack patch path where trustremotecode defaults to None instead of False, causing the security guard to be bypassed. Attackers can execute arbitrary Python code by crafting a malicious Hugging Face model repository...

Duplicate Advisory: Allowlisted pickle loaders still permit code execution in current source

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-x99w-6fgc-pmfw. This link is maintained to preserve external references. Original Description NLTK versions before 3.10.3 contain a remote code execution vulnerability in allowlisted pickle loaders that trust...

PYSEC-2026-3735

NLTK versions before 3.10.3 contain a remote code execution vulnerability in allowlisted pickle loaders that trust entire module namespaces instead of specific safe callables. Attackers can craft malicious pickle payloads invoking dangerous in-namespace functions like ReppTokenizer.execute and...

CVE-2026-76843

The official Flair wheels for 0.15.0 and 0.15.1 still contain flair/models/clustering.py, whose ClusteringModel.load static method returns pickle.loadsjoblib.loadstrmodelfile and so executes arbitrary Python while loading a model file. Loading a model supplied by an attacker therefore runs that...

CVE-2026-76843

CVE-2026-76843 affects the official Flair wheels for versions 0.15.0 and 0.15.1 . The file flair/models/clustering.py remains present in the distributed package despite being removed from the documented API. Its ClusteringModel.load static method deserializes via pickle.loads(joblib.load(str(mode...
