Name of the Vulnerable Software and Affected Versions wpDiscuz plugin for WordPress versions up to, and including, 7.6.15

Description The issue is related to Stored Cross-Site Scripting via the Alternative Text field of an uploaded image due to insufficient input sanitization and output escaping. This allows authenticated attackers with author-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 7.6.15, update to a version later than 7.6.15 to resolve the issue. As a temporary workaround, consider restricting access to the image upload feature to minimize the risk of exploitation. Additionally, restrict the use of the Alternative Text field until a patch is available.
