n8n-MCP: Cross-tenant access to workflow version backups in multi-tenant HTTP deployments
Impact In multi-tenant HTTP deployments — where a single n8n-mcp server serves several tenants — the locally stored workflow version history the automatic backups taken before workflow updates was not isolated per tenant. An authenticated tenant could read workflow version snapshots belonging to...

Summary In multi-tenant HTTP mode ENABLE MULTI TENANT=true, an authenticated tenant could, under certain conditions, reach n8n-mcp's local default-scope workflow versions backups instead of being confined to its own tenant scope. This affects n8n-mcp's own local workflow-version storage, not a...
PYSEC-2026-3403 vLLM: GGUF dequantize kernel int truncation exposes uninitialized GPU memory in multi-tenant serving
Summary Integer truncation of tensor dimensions in vLLM's GGUF dequantize kernels csrc/quantization/gguf/ggufkernel.cu causes partial tensor processing. The output tensor is allocated at full size via torch::empty uninitialized memory, but the dequantize CUDA kernel processes only a truncated...

PYSEC-2026-2660 MLflow authenticated users can enumerate any registered model versions due to lack of per-model permissions checks
In mlflow/mlflow versions up to 3.9.0, the SearchModelVersions REST API endpoint and the mlflowSearchModelVersions GraphQL query lack proper per-model authorization checks when basic authentication is enabled. This allows any authenticated user to enumerate all model versions across all registere...

PYSEC-2026-2656 Arbitrary file write via tar traversal in mlflow
A vulnerability in MLflow's pyfunc extraction process allows for arbitrary file writes due to improper handling of tar archive entries. Specifically, the use of tarfile.extractall without path validation enables crafted tar.gz files containing .. or absolute paths to escape the intended extractio...

PYSEC-2026-3434 zae-limiter: DynamoDB hot partition throttling enables per-entity Denial of Service
Summary All rate limit buckets for a single entity share the same DynamoDB partition key namespace/ENTITYid. A high-traffic entity can exceed DynamoDB's per-partition throughput limits 1,000 WCU/sec, causing throttling that degrades service for that entity — and potentially co-located entities in...
