## Sentinel Flags MEDIUM Severity DoS Risk in Axios Proxy Configuration
A critical security gap in the proxy's HTTP request handling has been identified, exposing the system to potential Denial of Service (DoS) attacks. The vulnerability stems from missing size and timeout boundaries on outbound requests made via the `axios` library. Without these limits, a malicious actor could force the proxy to fetch indefinitely large payloads or hang on deliberately slow connections, leading to server memory and resource exhaustion.

The flaw was located within the `api/social.ts` and `api/linkMetaRoutes.ts` files, where the `axios` configurations lacked explicit constraints. The fix, implemented by an automated process initiated by @samixisme, involved adding precise `timeout`, `maxContentLength`, and `maxBodyLength` parameters to these configurations. This change hardens the proxy against resource exhaustion attacks by capping the size of data it will process and the time it will wait for a response.

While the code validation passes without breaking existing proxy functionality, the MEDIUM severity rating underscores a persistent operational risk. Such configuration oversights in core API routes can create systemic weaknesses, leaving backend services vulnerable to disruption. The automated remediation highlights a shift towards proactive, code-level security enforcement, but it also signals that similar latent vulnerabilities could exist elsewhere in the codebase if not systematically audited.
