CVE-2026-42549 - Flight: Path traversal in `make:controller` CLI creates arbitrary directories outside project root
CVE ID :CVE-2026-42549
Published : May 13, 2026, 8:16 p.m. | 51 minutes ago
Description :Flight is an extensible micro-framework for PHP. Prior to 3.18.1, the make:controller CLI command calls mkdir(..., recursive: true) on a path built from the user-supplied controller name, before Nette's class-name validation runs. The class-file write is correctly rejected by Nette when the name contains /, but the recursive directory creation side effect is already committed — including directories located outside the project root through ../ traversal. This vulnerability is fixed in 3.18.1.
Severity: 4.4 | MEDIUM
