CVE-2023-52075Public exploitNetwork attack vector

Service interruption via uncached API errors

Published Dec 27, 2023 · Updated Sep 9, 2024

Denial of service in ReVanced API 71f81f7f20cd26fd707335bca9838fa3e7df20d2 and earlier allows remote attackers to interrupt service. Cloudflare does not cache API error responses, so repeated requests reach the backend until its rate limiter activates and server load rises. No authentication or user interaction is required, and the resulting outage affects every consumer of the shared API.
