CVE-2026-90504 Details
Description
A vulnerability has been found in vvbbnn00 WARP-Clash-API up to c7bf2360073959861219b422e51ae86411051b46. The impacted element is the function authorized. The manipulation of the argument SECRET_KEY leads to missing authentication. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. Continious delivery with rolling releases is used by this product. Therefore, no version details of affected nor updated releases are available. 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.
A critical authentication bypass vulnerability has been identified in vvbbnn00 WARP-Clash-API versions prior to c7bf2360073959861219b422e51ae86411051b46. The issue arises in the 'authorized' function, where the absence of a defined SECRET_KEY environment variable allows unauthenticated access to account-management endpoints. This flaw can be exploited remotely, particularly in deployments that follow the default configuration, which does not require setting the SECRET_KEY.
