Pull Request Overview

This PR updates the 'shell-quote' dependency to version 1.8.4 to fix object-token shape validation. Although Codacy identifies the PR as being up to standards, this review surfaced several high-severity security vulnerabilities within the lockfile that should be addressed before merging. Specifically, the 'fast-uri' and 'tmp' packages are affected by path traversal and security filter bypass vulnerabilities (CVE-2026-6322, CVE-2026-6321, and CVE-2026-44705). Additionally, the version bump is only reflected in the lockfile; 'package.json' remains unchanged, and there are no automated tests included to verify the fix.

About this PR

• The changes are currently limited to 'yarn.lock'. If 'shell-quote' is a direct dependency, 'package.json' should also be updated to reflect the 1.8.4 version to ensure the project's dependency definition is consistent with the installed versions.
• The PR lacks automated tests to verify that 'shell-quote' now correctly handles object-token shapes as intended by the 1.8.4 release.

yarn.lock

_{line 2714 🔴 HIGH RISK}
Suggestion: High-severity security vulnerabilities (CVE-2026-6322, CVE-2026-6321) have been detected in 'fast-uri'. Flaws in authority delimiter handling and path normalization can allow for security filter bypass or path traversal. Remediation of this dependency is recommended to mitigate these risks.

_{line 10114 🔴 HIGH RISK}
Suggestion: The 'tmp' package is affected by a path traversal vulnerability (CVE-2026-44705). This can allow for directory escape if unsanitized input is used for temporary file prefixes or suffixes.

_{line 10119 🔴 HIGH RISK}
Suggestion: A version of the 'tmp' package containing a path traversal vulnerability (CVE-2026-44705) was detected. Addressing this is necessary to ensure file system integrity for operations involving temporary files.

Test suggestions

• Verify that shell-quote correctly handles and validates object-token shapes as per the 1.8.4 fix.
