From 45dabc342f1dcfbb2ab7b5d340cc86903bfd2cda Mon Sep 17 00:00:00 2001 From: carlos-alm Date: Thu, 11 Jun 2026 23:38:41 -0600 Subject: [PATCH 1/8] fix(deps): remove malicious tree-sitter-erlang, fix 3 moderate vulns MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Removes the WhatsApp/tree-sitter-erlang devDependency flagged as malware (GHSA-rphw-c8qj-jv84, CWE-506). The committed WASM in grammars/ was validated clean (correct export name, no disallowed imports) — Erlang grammar support is unaffected. Also runs npm audit fix to bump hono (→4.12.25), protobufjs (→7.5.8), and qs (→6.15.2) to their patched versions. All three were transitive deps; no direct-dependency changes required. See scripts/build-wasm.ts for instructions on rebuilding the Erlang WASM from a safe source if needed. --- package-lock.json | 115 +++++++++--------------------------------- package.json | 1 - scripts/build-wasm.ts | 5 +- 3 files changed, 27 insertions(+), 94 deletions(-) diff --git a/package-lock.json b/package-lock.json index 7e871f8de..2fe6fb17d 100644 --- a/package-lock.json +++ b/package-lock.json @@ -38,7 +38,6 @@ "tree-sitter-cuda": "^0.21.1", "tree-sitter-dart": "^1.0.0", "tree-sitter-elixir": "^0.3.5", -
