Cross-Architecture Testing for Compiler-Introduced Security Bugs
Todays computer systems are insecure. The semantics of mainstream low-level languages like C provide no security against devastating vulnerabilities like buffer overflows and control-flow hijacking. Even for safer languages, establishing security with respect to the languages semantics does not prevent low-level attacks. All the abstraction and security guarantees of the source language may be lost when interacting with low-level code, e.g., when using libraries. Secure compilation is an emerging field that puts together advances in programming languages, security, verification, systems ...

An attacker could have taken over a future user account by abusing the session creation endpoint, which was consistently returning the same session token (although not yet valid) for the same user. Once the legitimate user validates the SMS code for that session token, the session would have become valid for both the legitimate user and the attacker.
