PYSEC-2026-462 PraisonAI Vulnerable to Remote Code Execution via YAML Deserialization in Agent Definition Loading

Summary The AgentService.loadAgentFromFile method uses the js-yaml library to parse YAML files without disabling dangerous tags such as !!js/function and !!js/undefined. This allows an attacker to craft a malicious YAML file that, when parsed, executes arbitrary JavaScript code. An attacker can...

PYSEC-2026-468 PraisonAI Has Authentication Bypass via OAuthManager.validate_token()

Summary OAuthManager.validatetoken returns True for any token not found in its internal store, which is empty by default. Any HTTP request to the MCP server with an arbitrary Bearer token is treated as authenticated, granting full access to all registered tools and agent capabilities. Details...

PraisonAI has critical RCE via `type: job` workflow YAML

praisonai workflow run loads untrusted YAML and if type: job executes steps through JobWorkflowExecutor in jobworkflow.py.This supports: - run: → shell command execution via subprocess.run- script: → inline Python execution via exec- python: → arbitrary Python script execution A malicious YAML fi...

PYSEC-2026-456 PickleScan's pkgutil.resolve_name has a universal blocklist bypass

Summary pkgutil.resolvename is a Python stdlib function that resolves any "module:attribute" string to the corresponding Python object at runtime. By using pkgutil.resolvename as the first REDUCE call in a pickle, an attacker can obtain a reference to ANY blocked function e.g., os.system,...

PYSEC-2026-501 pyminizip affected by zlib's integer overflow/heap based buffer overflow vulnerability due to vulnerable dependency

MiniZip in zlib through 1.3 has an integer overflow and resultant heap-based buffer overflow in zipOpenNewFileInZip464 via a long filename, comment, or extra field. NOTE: MiniZip is not a supported part of the zlib product. pyminizip uses version 1.2.11 of zlib's code...

TensorFlow has a heap out-of-buffer read vulnerability in the QuantizeAndDequantize operation

ImpactAttackers using Tensorflow can exploit the vulnerability. They can access heap memory which is not in the control of user, leading to a crash or RCE.When axis is larger than the dim of input, c-Diminput,axis goes out of bound.Same problem occurs in the QuantizeAndDequantizeV2/V3/V4/V4Grad...

PYSEC-2026-271 Apache Airflow Hive Provider vulnerable to code injection

Apache Software Foundation's Apache Airflow Hive Provider before 6.0.0 is vulnerable to improper control of generation of code...

Gradio allows users to access arbitrary files

ImpactThis vulnerability allows users of Gradio applications that have a public link such as on Hugging Face Spaces to access files on the machine hosting the Gradio application. This involves intercepting and modifying the network requests made by the Gradio app to the server. PatchesYes, the...

llama-cpp-python vulnerable to Remote Code Execution by Server-Side Template Injection in Model Metadata

Descriptionllama-cpp-python depends on class Llama in llama.py to load .gguf llama.cpp or Latency Machine Learning Models. The init constructor built in the Llama takes several parameters to configure the loading and running of the model. Other than NUMA, LoRa settings, loading tokenizers, and...

Vanna prompt injection code execution

The Vanna library uses a prompt function to present the user with visualized results, it is possible to alter the prompt using prompt injection and run arbitrary Python code instead of the intended visualization code. Specifically - allowing external input to the library’s “ask” method with...

Flask-AppBuilder vulnerable to incorrect authentication when using auth type OpenID

ImpactWhen Flask-AppBuilder is set to AUTHTYPE AUTHOID, allows an attacker to forge an HTTP request, that could deceive the backend into using any requested OpenID service. This vulnerability could grant an attacker unauthorised privilege access if a custom OpenID service is deployed by the...

PYSEC-2026-296 Insecure deserialization in BentoML

Browser Use allows bypassing `allowed_domains` by putting a decoy domain in http auth username portion of a URL

Summary During a manual source code review, ARIMLABS.AI researchers identified that the browseruse module includes an embedded whitelist functionality to restrict URLs that can be visited. This restriction is enforced during agent initialization. However, it was discovered that these measures can...

PYSEC-2026-381 Langroid has a Code Injection vulnerability in TableChatAgent

Summary TableChatAgent uses pandas eval. If fed by untrusted user input, like the case of a public-facing LLM application, it may be vulnerable to code injection. PoC For example, one could prompt the Agent: Evaluate the following pandas expression on the data provided and print output:...

PYSEC-2026-358 InvokeAI Arbitrary File Deletion vulnerability
