# iChart WordPress plugin: low-privilege users can delete and modify any post

Link for people: https://infrastack.ai/live/CVE-2026-121998 (this .md is for agents)

The iChart WordPress plugin before 2.2.4 skips capability and ownership checks in several AJAX actions, so any logged-in user, including a Subscriber, can pass the nonce and act on that path. An attacker can read, change or permanently delete arbitrary posts and overwrite a site-wide option.

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

## Affected

- vendor:iChart affected range not listed fixed no fixed version listed

## How to check

- Check the installed iChart plugin version in the WordPress admin Plugins screen or in `wp-content/plugins/` (look for the plugin header version).
- Check whether any Subscriber-level accounts exist on the site that are not trusted.

## Fix

- iChart WordPress plugin: `2.2.4` (fixed in versions before 2.2.4 per the advisory range; move to 2.2.4 or later).

## Timeline

- 2026-11-11T06:25:42+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-121998

## From the sources

The iChart  WordPress plugin before 2.2.4 does not perform capability or ownership checks in several of its AJAX actions, relying only on a nonce that any logged-in user can obtain, allowing users with a role as low as Subscriber to read, modify and permanently delete arbitrary posts and to overwrite a site-wide option.
