Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Corruption: Buffer overruns and heap out-of-bounds access in sampling functions (like repeat penalty sampling) can lead to arbitrary code execution or application crashes when processing model outputs with unchecked token windows.
Memory Safety: A use-after-free vulnerability can occur during embedding thread teardown if the model pointer is deleted out of sync with active background tasks, threatening application stability and state integrity.
Injection: Manual JSON construction via string concatenation allows malicious input to break the JSON structure, leading to injection attacks when sending data to the ingest API.
