CVE-2026-15753Public exploitNetwork attack vector

Unauthorized withdrawal approval via state-changing GET request

Published Jul 14, 2026 · Updated Jul 14, 2026

Trusting HTTP permission methods in xianyu-auto-reply Server allows remote attackers to approve withdrawals via crafted GET requests. The withdrawal-review route changes approval state while handling GET, and its deterministic token derives from a record ID, action, and hard-coded secret. Network access and a guessed pending record ID are sufficient to compute the token and change a withdrawal from pending review to approved without administrator authentication.
