From 2242fe36665d57c81ce8eabfcbc0bd6c8d1bc22c Mon Sep 17 00:00:00 2001 From: mertcano <35747700+mertcano@users.noreply.github.com> Date: Sat, 19 Sep 2026 13:23:58 +0300 Subject: [PATCH 01/11] ci(security): replace pull_request_target with pull_request and restrict token permissions ## Description Addresses the pipeline code injection / remote code execution (RCE) vulnerability documented in the workspace audit report for `blocklist`. Previously, the workflow listened on `pull_request_target` while running `yarn install` and executing arbitrary repository scripts (`node ./ci.js`). Because `pull_request_target` runs in the context of the base branch with repository write tokens accessible by default, a malicious pull request from a fork could trigger arbitrary code execution and compromise repository assets. ## Key Changes & Remediations * **Safe PR Triggering (`.github/workflows/ci.yml`)**: - Replaced `pull_request_target` with standard `pull_request` (`opened`, `reopened`, `synchronize`), isolating untrusted fork code execution from base branch secrets. * **Least-Privilege Token Permissions (`.github/workflows/ci.yml`)**: - Enforced `permissions: contents: read` explicitly on the job to prevent privilege escalation. * **Action Pinning (`.github/workflows/ci.yml`)**: - Pinned `actions/checkout` and `actions/setup-node` to immutable commit SHAs. ## Verification - Validated YAML schema and syntax (`yamllint .github/workflows/ci.yml`). - Confirmed workflow event trigger restrictions. --- .github/workflows/ci.yml | 56 +++++++++++++++++++++------------------- 1 file changed, 29 insertions(+), 27 deletions(-) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index a378845..1d94748 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -1,27 +1,29 @@ -name: Ensure Formatting -
