Fix Stored XSS

[gtsp233]

Hi, I've discovered a stored Cross-Site Scripting (XSS) vulnerability in your GitHub repository:

Vulnerability Details:
Version Affected: All versions
Severity: [High/Critical – Stored XSS can have a significant impact. Adjust based on your assessment]
Description: The vulnerability allows malicious attacks to inject scripts through a direct network request. Once embedded, any user viewing the posts' description will execute the malicious script.

Steps to Reproduce:
Send a direct POST or PUT request (bypassing the user interface) to /api/posts with a payload description containing the malicious script.
After the post is successfully created or edited, any user who views the post list or the specific post's details will run the malicious script.

Suggested Fix or Mitigation:
Server-side: When creating the post, it's essential to sanitize the user's input (description) before processing it to ensure malicious scripts are neutralized.
Client-side: Prior to displaying the post's description using dangerouslySetInnerHtml, ensure that the description is sanitized using libraries like DOMPurify to prevent script execution.
