CVE-2023-5357

Name of the Vulnerable Software and Affected Versions Instagram for WordPress plugin for WordPress versions up to, and including, 2.1.6

Description The issue is related to Stored Cross-Site Scripting via shortcodes due to insufficient input sanitization and output escaping on user-supplied attributes. This allows authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 2.1.6, update to a version higher than 2.1.6 to resolve the issue. As a temporary workaround, consider restricting contributor-level and above permissions to minimize the risk of exploitation. Additionally, avoid using shortcodes with user-supplied attributes until the issue is resolved.
