Content Egg: Contributor imports execute under a privileged preset author's identity
The Content Egg WordPress plugin before 11.9.0 does not verify that a user running its bulk content-import feature is authorized for the import preset they select, and switches to the preset author's identity before creating the resulting post, allowing users with contributor-level access and above to store arbitrary web scripts unfiltered under a privileged user's account, executing in the context of anyone who later views that content. The authoritative export identifies the fixed release as 11.9.0.

This CVE was published Sep 30, 2026 and is one of 8 known issues for this plugin.
Update, patch or deactivate.
Update Content Egg to 11.9.0 or a later supported release. An application-level fix should validate stored/request input and escape it for the final HTML, attribute, URL or DOM context. Remove persisted malicious content where storage is involved.
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.
