AI Engine: Unauthorized modification of post titles and excerpts
The AI Engine WordPress plugin before 3.8.6 does not check that the caller is allowed to edit the targeted object before updating its title and excerpt, allowing users with the Editor role and above to modify arbitrary posts of any type, including content they cannot otherwise edit such as navigation menus, block templates, global styles and WooCommerce coupons. Other endpoint, parameter, role or implementation details not named in this export are not established by this record. Affected versions: before 3.8.6.

- CWE-862 — Missing Authorization
This CVE was published Oct 21, 2026 and is one of 44 known issues for this plugin.
Update, patch or deactivate.
The authoritative export identifies 3.8.6 as fixed. Update to the applicable fixed release or a later supported release. Enforce server-side caller, object and operation permissions at the disclosed trust boundary; do not treat knowledge of identifiers or a nonce as authorization.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
