From a1b594043210c85bc638ac9507ed6ec3ae9aa5c2 Mon Sep 17 00:00:00 2001 From: Ejiaka Princess Date: Wed, 21 Oct 2026 18:52:36 +0100 Subject: [PATCH 1/4] test(utils): add symlink-attack coverage for safe static path resolver Expands tests/unit/utils/safe-static-path.test.ts with on-disk symlink scenarios: a filename resolving to a symlink inside the upload dir, and an upload dir that is itself a symlink. Confirms resolveSafeStaticPath stays confined to the configured upload dir in both cases, since it never calls fs.realpath and only ever resolves string paths.
