Name of the Vulnerable Software and Affected Versions Base64 Encoder/Decoder WordPress plugin versions 0.9.2 and earlier

Description The issue concerns a lack of CSRF check when updating settings in the plugin, along with missing sanitization and escaping. This could allow attackers to make logged-in admins add Stored XSS payloads via a CSRF attack.

Recommendations For versions 0.9.2 and earlier, consider disabling the settings update functionality until a patch is available to prevent potential CSRF attacks. Restrict access to the plugin's settings to minimize the risk of exploitation. Avoid using the plugin until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
