FKIE_CVE-2026-90507

Vulnerability from fkie_nvd - Published: 2026-09-13 10:16 - Updated: 2026-09-14 20:56
Severity
6.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L
Summary
A vulnerability was identified in vvbbnn00 WARP-Clash-API up to c7bf2360073959861219b422e51ae86411051b46. Affected is the function get_surge_subscription of the file services/subscription.py of the component Subscription Handler. Such manipulation of the argument key leads to improper access controls. The attack may be launched remotely. The exploit is publicly available and might be used. This product operates on a rolling release basis, ensuring continuous delivery. Consequently, there are no version details for either affected or updated releases. The vendor was contacted early about this disclosure but did not respond in any way. This vulnerability only affects products that are no longer supported by the maintainer.
