The PublishPress Revisions plugin for WordPress suffers from a reflected cross-site scripting vulnerability due to the use of add_query_arg without proper escaping on URL parameters. This allows unauthenticated attackers to inject arbitrary web scripts that execute when a user clicks a maliciously crafted link. The vulnerability affects all versions up to and including 3.5.14. The CVSS 3.1 base score is 6.1, reflecting a medium severity with network attack vector, low attack complexity, no privileges required, user interaction required, and partial confidentiality and integrity impact. No patch or remediation details are currently provided by the vendor.

Successful exploitation can lead to execution of arbitrary scripts in the context of the affected website for users who click on malicious links. This can result in partial confidentiality and integrity impacts, such as theft of user session data or manipulation of displayed content. There is no indication of availability impact or known active exploitation.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should exercise caution with links related to the PublishPress Revisions plugin and consider disabling or removing the plugin if feasible. Monitor vendor channels for updates and apply any official patches promptly once available.
