Deserialization of Untrusted Data

Severity
CWE	CWE-502: Deserialization of Untrusted Data
Confidence Level	Low
Impact Level	High
Likelihood Level	Medium

Description

Using OCaml's Marshal module to deserialize data from untrusted sources is unsafe because it doesn't enforce type safety or data integrity. This can allow attackers to craft malicious inputs that compromise your application.

Impact

If exploited, an attacker could trigger out-of-bounds reads, cause crashes, or execute arbitrary code, potentially leading to data leaks or full system compromise. This puts both application integrity and user data at significant risk.
