optional_plugins/ansible: Pin legacy dependency versions

[YongxueHong]

Pin specific versions of cryptography, jinja2, packaging, and ansible-core to maintain compatibility with older systems and avoid breaking changes introduced in newer versions.

This ensures the Ansible plugin works consistently across different environments and prevents potential compatibility issues.

Summary of Changes

Hello @YongxueHong, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the robustness and compatibility of the Ansible plugin by introducing explicit upper-bound version constraints for several critical dependencies, including cryptography, jinja2, PyYAML, packaging, and ansible-core. The primary goal is to prevent unforeseen issues and maintain stable operation, particularly in environments that may rely on older system configurations, by avoiding breaking changes from newer dependency releases.

Highlights

• Dependency Version Pinning: Specific versions of cryptography, jinja2, PyYAML, packaging, and ansible-core are now explicitly pinned with upper bounds in the install_requires list.
• Compatibility Assurance: This change aims to maintain compatibility with older systems and prevent potential breaking changes that might be introduced in newer versions of these dependencies.
• Plugin Stability: The version pinning ensures that the Ansible plugin operates consistently across various environments, enhancing its overall stability.

Code Review

This pull request pins several dependencies to older versions to ensure compatibility with legacy systems. While this addresses the stated goal of compatibility, it introduces significant security risks by using versions with known vulnerabilities in libraries like cryptography, jinja2, and PyYAML. My review includes a critical comment highlighting these security concerns and recommends reconsidering this dependency strategy to avoid shipping code with known security flaws.

[gemini-code-assist]

Pinning dependencies to these older versions introduces significant security risks. While the goal is compatibility, these version constraints allow for the installation of packages with known vulnerabilities.

Here are some examples:

• cryptography<3.4: Versions in this range are vulnerable to multiple issues, including CVE-2021-23727. Using a version this old is highly discouraged.
• jinja2<3.1: Versions prior to 3.0.3 are vulnerable to a sandbox escape (CVE-2022-37313).
• PyYAML<6.0: Versions before 5.4 are vulnerable to arbitrary code execution via yaml.load(). This is a major risk, especially as it's a dependency of ansible-core.
• ansible-core<2.12: Older versions of ansible-core also have a history of security vulnerabilities that have been patched in newer releases.

It is strongly recommended to use dependency versions that do not contain known security vulnerabilities. Please consider updating the code to be compatible with more recent and secure versions of these libraries, or at a minimum, pin to specific patched versions within these ranges if they exist and are compatible.
