The Curator.io WordPress plugin suffers from a stored XSS vulnerability due to improper neutralization of input in the 'feed_id' attribute. This allows authenticated users with Contributor or higher privileges to inject arbitrary JavaScript code into pages, which executes when other users access those pages. The vulnerability affects all versions up to 1.9.1. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, privileges required at the contributor level, no user interaction, and impacts on confidentiality and integrity with no impact on availability. No patch or remediation details are provided in the available data.

Successful exploitation allows an authenticated user with Contributor-level access or higher to inject and execute arbitrary scripts in the context of the affected site. This can lead to partial confidentiality and integrity impacts, such as theft of sensitive information or unauthorized actions performed on behalf of other users. There is no indication of availability impact. No known exploits have been reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit Contributor-level access to trusted users only. Monitor for plugin updates from Curator.io and apply them promptly once released. Avoid using affected versions of the plugin if possible.
