CVE-2026-85410 pixarlabs CVE debrief

Who should care

Defenders responsible for WordPress installations with the Master Addons for Elementor plugin should assess exposure and prioritize updates and compensating controls. This includes reviewing the plugin's version, assessing the environment for potential exposure, and implementing measures to restrict post modifications and deletions. Additionally, defenders should monitor for suspicious activity and verify the integrity of posts and metadata.

Why it matters

CVE-2026-85410 is an authorization bypass vulnerability in the Master Addons for Elementor plugin for WordPress. Authenticated attackers with contributor-level access can modify or delete arbitrary posts. Defenders should prioritize updates, assess exposure, and implement compensating controls.

• Authenticated attackers can modify arbitrary post titles and metadata.
• Authenticated attackers can permanently delete arbitrary posts.
• Defenders need to verify and update the plugin to prevent exploitation.
• Exposure assessment and compensating controls are necessary.

Technical summary

The Master Addons for Elementor plugin for WordPress is vulnerable to authorization bypass due to improper verification of user authorization. This allows authenticated attackers with contributor-level access to modify titles and metadata of arbitrary posts or permanently delete posts. The vulnerability is caused by the plugin not properly verifying that a user is authorized to perform an action, making it possible for attackers to supply an attacker-controlled popup_id and modify or delete posts. The required nonce is emitted on the edit-jltma_popup admin screen, which is accessible to Contributors because the jltma_popup custom post type is registered with capability_type='post'.

Defensive priority

Defenders should prioritize verifying and updating the Master Addons for Elementor plugin, assessing exposure in their environments, and implementing compensating controls to restrict post modifications and deletions.

Recommended defensive actions

• Verify and update the Master Addons for Elementor plugin to the latest version.
• Assess exposure in environments and implement compensating controls to restrict post modifications and deletions.
• Monitor for suspicious post modifications and deletions.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.

Evidence notes
