SummaryThe default MLflow Tracking Server mlflow server, no authentication, default SQLite backend exposes the model-registry webhooks API unauthenticated, including a synchronous POST /api/2.0/mlflow/webhooks/id/test endpoint that returns the upstream response status and body to the caller. The...

MobSF has SSRF port restriction bypass in assetlinks_check

SummaryMobSF's Android App Link assetlinks checker validates only the manifest android:host value with validhost, but then appends the separate android:port value into the URL used for the server-side request. This bypasses the current port restriction in validhost and lets a crafted APK cause...

vLLM: Completion prompt lists fan out into unbounded engine requests

SummaryThe /v1/completions request model accepts prompt as a list of text prompts or a list of token-id prompts without any outer prompt-count bound. The serving path turns each element into a separate engine input, creates one engine generator per element, merges all generators, and allocates a...
