Prior to version 0.20.1, the library fails to enforce configured size limits on incoming request bodies when `Transfer-Encoding: chunked` is used or when no `Content-Length` header is provided. A remote attacker can send a chunked request without the terminating zero-length chunk, causing uncontrolled memory allocation on the server. This leads to potential exhaustion of system memory and results in a server crash or unresponsiveness. Version 0.20.1 fixes the issue by enforcing limits during parsing. If the limit is exceeded at any point during reading, the connection is terminated immediately. A short-term workaround through a Reverse Proxy is available. If updating the library immediately is not feasible, deploy a reverse proxy (e.g., Nginx, HAProxy) in front of the `cpp-httplib` application. Configure the proxy to enforce maximum request body size limits, thereby stopping excessively large requests before they reach the vulnerable library code.\n\ud83d\udccf Published: 2025-05-06T00:45:25.130Z\n\ud83d\udccf Modified: 2025-05-06T00:45:25.130Z\n\ud83d\udd17 References:\n1. https://github.com/yhirose/cpp-httplib/security/advisories/GHSA-px83-72rx-v57c\n2. https://github.com/yhirose/cpp-httplib/commit/7b752106ac42bd5b907793950d9125a0972c8e8e", "creation_timestamp": "2025-05-06T01:20:33.000000Z"} 2025-05-06T01:20:33+00:00 https://vulnerability.circl.lu/sighting/631c3983-433f-4613-9917-255deeb6b6ee/export 2026-06-11T23:01:08.401071+00:00 Automation user https://vulnerability.circl.lu/user/automation {"uuid": "631c3983-433f-4613-9917-255deeb6b6ee", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "GHSA-PX83-72RX-V57C", "type": "seen", "source": "Telegram/6XDP4M1wkfL7m7vq90Tisvnt9Hir_tEqb2ho5KerLaKNi_8", "content": "", "creation_timestamp": "2025-05-06T04:01:13.000000Z"} 2025-05-06T04:01:13+00:00
