Posts shared counter for social website Security & Risk Analysis

The "posts-shared-counter-for-social-website" plugin version 2.3 exhibits several concerning security practices despite a clean vulnerability history. The plugin exposes two AJAX handlers directly to the public without any authentication or capability checks, creating a significant attack surface for unauthorized actions. Furthermore, the presence of the `unserialize` function, coupled with taint analysis revealing two high-severity flows with unsanitized paths, strongly suggests a high risk of Remote Code Execution (RCE) or other serious vulnerabilities. While the plugin has no recorded CVEs, this historical absence should not be interpreted as current safety, especially given the static analysis findings. The low percentage of properly escaped output further exacerbates the risk, potentially leading to Cross-Site Scripting (XSS) vulnerabilities. The plugin's overall security posture is weak due to these fundamental flaws in handling user input and authentication, overshadowing the positive aspects like a moderate use of prepared statements.
