CVE-2026-48154Public exploitNetwork attack vectorHinoki check available

Unauthenticated process crash via concurrent map access

Published Aug 4, 2026 · Updated Aug 4, 2026

Race condition in InMemorySecret2FA in piLinux gorest before 1.12.2 allows remote attackers to crash the service via concurrent requests. Login and 2FA handlers concurrently read, write, and delete entries in an unsynchronized package-level Go map, causing an unrecoverable runtime error. Reachability requires 2FA-enabled workflows and overlapping login or verification requests; exploitation terminates the process without disclosing or altering data.
