At a glance
CVE-2026-0727 is a medium-severity Missing Authorization vulnerability in the Accordion and Accordion Slider WordPress plugin, affecting versions <= 1.4.5. It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 1.4.6; sites on affected versions should update now. Disclosed February 2026, reported by Kazuma Matsumoto.
Vulnerability Overview
The Accordion and Accordion Slider plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.4.5. This is due to the plugin not properly verifying that a user is authorized to perform an action in the 'wp_aas_save_attachment_data' and 'wp_aas_get_attachment_edit_form' functions. This makes it possible for authenticated attackers, with contributor level access and above, to read and modify attachment metadata including file paths, titles, captions, alt text, and custom links for any attachment on the site.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-862: Missing Authorization
Accordion and Accordion Slider <= 1.4.5 carries this weakness at wp_aas_save_attachment_data, and reaching it takes an account at Contributor level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Accordion and Accordion Slider the fix is 1.4.6: builds <= 1.4.5 are affected, anything from 1.4.6 onward is not.
Remediation
Update to version 1.4.6, 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: Accordion and Accordion Slider 1.4.6 closes this, and updating the plugin is the step that ends it.
