This issue tracks security vulnerabilities detected by Dependabot for **pyyaml**. We need to update the packages, and apply code fixes where necessary in the application. We need to pin the package version to the latest version compatible with the application code, but not any newer. We also need to add a FIX_SUMMARY.txt file which describes what was fixed in the pull request. However, since we are going to parse the FIX_SUMMARY.txt file in Javascript, it cannot contain any character that would break a JavaScript template string, such as backticks. --- **Dependabot Alert #10** - Security vulnerability in **pyyaml** Summary: Improper Input Validation in PyYAML Description: A vulnerability was discovered in the PyYAML library in versions before 5.3.1, where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the full_load method or with the FullLoader loader.

An attacker could use this flaw to execute arbitrary code on the system by abusing the python/object/new constructor. **Severity:** critical **Fixed in:** 5.3.1 More details: [Security Advisory](https://github.com/arthurthlee/testing/security/dependabot/10) <details> <summary>Full Vulnerability Details</summary> { "number": 10, "state": "open", "dependency": { "package": { "ecosystem": "pip", "name": "pyyaml" }, "manifest_path": "requirements/prd.txt", "scope": "runtime", "relationship": "unknown" }, "security_advisory": { "ghsa_id": "GHSA-6757-jp84-gxfx", "cve_id": "CVE-2020-1747", "summary": "Improper Input Validation in PyYAML", "description": "A vulnerability was discovered in the PyYAML library in versions before 5.3.1, where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the full_load method or with the FullLoader loader.
