At a glance
CVE-2026-15142 is a high-severity Improper Privilege Management vulnerability in the Real Estate Manager Pro WordPress plugin, affecting versions <= 12.8.6. It carries a CVSS score of 7.5 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 12.8.7; sites on affected versions should update now. Disclosed August 2026, reported by 0xd4rk5id3.
Vulnerability Overview
The Real Estate Manager Pro plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 12.8.6. This is due to improper capability handling in the allow_attachment_actions() function, which can treat a target user ID as a media attachment ID during user capability checks. This makes it possible for authenticated attackers, with Subscriber-level access and above, to edit an administrator account and escalate their privileges to Administrator when the targeted user ID matches the ID of an existing media attachment.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-269: Improper Privilege Management
Real Estate Manager Pro <= 12.8.6 carries this weakness at allow_attachment_actions(), and reaching it takes an account at Subscriber level or above. Improper privilege management means the code lets an account end up with capabilities its role should not have.
It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For Real Estate Manager Pro the fix is 12.8.7: builds <= 12.8.6 are affected, anything from 12.8.7 onward is not.
Remediation
Update to version 12.8.7, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Real Estate Manager Pro 12.8.7 closes this, and updating the plugin is the step that ends it.
