CVE-2026-90506Network attack vectorHinoki check available

Unspecified impact via unsynchronized account persistence

Published Sep 13, 2026 · Updated Sep 13, 2026

A race condition in WARP-Clash-API at commit c7bf236 allows remote attackers to cause unspecified impact through the Save Account Job. The periodic account-save task fetches current Cloudflare account data and persists the shared account object without published synchronization or atomic replacement. Exploitation requires remote access and a high-complexity timing window; the public record does not disclose the resulting account-state consequence.
