CVE-2026-0727: 
WordPress vulnerability analysis and mitigation

CVE-2026-0727 is an authorization bypass vulnerability in the Accordion and Accordion Slider plugin for WordPress, affecting all versions up to and including 1.4.5. The flaw allows authenticated attackers with contributor-level access or above to read and modify attachment metadata without proper authorization. It was published on February 14, 2026, and carries a CVSS v3.1 base score of 5.4 (Medium) (Red Hat CVE).

The vulnerability is classified as CWE-862 (Missing Authorization) and stems from the plugin's failure to properly verify user authorization in two functions: wp_aas_save_attachment_data and wp_aas_get_attachment_edit_form. An authenticated attacker with at minimum contributor-level access can send crafted requests to these functions over the network without any user interaction, exploiting the missing access control checks. The attack requires low privileges, low complexity, and no special conditions beyond a valid WordPress account (Red Hat CVE).

Successful exploitation allows an attacker to read and modify attachment metadata for any attachment on the affected WordPress site, including file paths, titles, captions, alt text, and custom links. The confidentiality and integrity impacts are both rated Low, with no availability impact, meaning attackers cannot delete content or crash the site but can expose sensitive file path information and tamper with media metadata site-wide (Red Hat CVE).

No public proof-of-concept exploit code or evidence of in-the-wild exploitation has been reported for CVE-2026-0727. The EPSS score is approximately 0.025%, indicating a low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Exploitation requires a valid WordPress account with at least contributor-level privileges, which limits the attacker pool (Red Hat CVE).

1. Reconnaissance: Identify WordPress sites running the Accordion and Accordion Slider plugin (bqworks) at version 1.4.5 or earlier using tools like WPScan or by inspecting plugin directories.
2. Obtain Contributor Access: Register or compromise a WordPress account with at minimum contributor-level privileges on the target site.
3. Trigger Unauthorized Read: Send an authenticated HTTP request to the wp_aas_get_attachment_edit_form AJAX action, supplying an arbitrary attachment ID. Due to missing authorization checks, the server returns metadata for any attachment regardless of ownership.
4. Trigger Unauthorized Write: Send an authenticated HTTP request to the wp_aas_save_attachment_data AJAX action with a target attachment ID and modified metadata values (e.g., altered file path, caption, or custom link) to overwrite existing attachment data.
5. Leverage Gathered Data: Use exposed file paths or modified metadata to facilitate further reconnaissance or social engineering attacks against site visitors (Red Hat CVE).

• Logs: WordPress access logs showing repeated authenticated POST requests to wp-admin/admin-ajax.php with action=wp_aas_save_attachment_data or action=wp_aas_get_attachment_edit_form from contributor-level accounts, especially targeting attachment IDs not owned by that user.
• Database: Unexpected changes to WordPress attachment post meta fields (e.g., _wp_attachment_metadata, _wp_attached_file, caption, alt text) for attachments not belonging to the authenticated user making the changes.
• Network: Unusual volume of AJAX requests to admin-ajax.php from a single low-privilege user account iterating over sequential attachment IDs.

Users should update the Accordion and Accordion Slider plugin (bqworks) to a version beyond 1.4.5 that includes proper authorization checks in the affected functions. Until a patched version is available, site administrators should consider restricting contributor-level registrations, disabling the plugin, or using a WordPress security plugin (e.g., Wordfence) to monitor and block suspicious AJAX requests targeting the affected actions (Red Hat CVE).
