Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Attackers can bypass input validation to write arbitrary files or overwrite system files on the host during asset rendering, a pattern also illustrated by CVE-2026-30121. Proper path canonicalization and prefix validation are required before executing file writes.
Auth Bypass: Deploying serverless endpoints with public-read permissions or allowing unauthenticated service invocation compromises private media assets and exposes rendering infrastructure to unauthorized execution and financial exhaustion.
Denial of Service: Unsafe panic-propagation ('unwrap' calls), manual memory leaks via 'std::mem::forget', and failure to properly close write streams or evict duplicate keys can cause process crashes and exhaust system memory or file descriptors under load.
