# WordPress RSVP plugin: stored XSS lets attackers inject scripts into pages

Link for people: https://infrastack.ai/live/CVE-2026-121570 (this .md is for agents)

The RSVP and Event Management WordPress plugin by WP Chill fails to sanitize some input, so stored cross-site scripting is possible. An attacker who can submit that input can run scripts in the browsers of people who view the affected page.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed plugin version in the WordPress admin under Plugins, or look for the RSVP and Event Management plugin folder on the server.
- Compare the installed version against `2.7.17`; the sources list versions through `2.7.17` as affected, with no earlier bound given.

## Fix

- RSVP and Event Management (WordPress plugin): versions through `2.7.17` are affected; the sources do not name a fixed version.
