CVE-2026-30960Public exploit

Arbitrary code execution via unvalidated JIT instructions

Published Mar 10, 2026 · Updated Mar 10, 2026

Code injection in Apich Organization RSSN before 0.2.9 allows local users to execute arbitrary code through the CFFI-exposed JIT engine. The CFFI layer accepts attacker-supplied parameters or instruction sequences and passes them into JIT code generation without adequate validation. Exploitation requires a host application to expose the CFFI path to untrusted data or models, and the resulting code runs with the host process's privileges.
