CVE-2026-42552
CVE-2026-42552 updated by NVD
Summary
Flight is an extensible micro-framework for PHP. Prior to 3.18.1, the default error handler Engine::_error() writes the full exception message, exception code, and stack trace (including absolute filesystem paths) directly into the HTTP 500 response, with no debug gating. Production deployments leak internal paths, any secret interpolated into an exception message, and full module structure — giving attackers primitives for chaining other weaknesses (LFI, path traversal). This vulnerability is fixed in 3.18.1.
