CVE-2023-42328Public exploitNetwork attack vector

Remote code execution via hardcoded session secret

Published Sep 18, 2023 · Updated Sep 25, 2024

Hard-coded credential vulnerability in PeppermintLabs Peppermint 0.2.4 and earlier allows remote authenticated users to execute arbitrary code via a session cookie. The NextAuth configuration stores a constant secret in the application source, letting forged JWT session cookies impersonate users and expose protected data. A remote user with low-level authenticated access can submit the forged cookie; successful use permits account-level data access and server-side code execution.
