CVE-2025-15524 in Gallery by FooGallery Plugin
Summary
by MITRE • 02/11/2026
The Gallery by FooGallery plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the ajax_get_gallery_info() function in all versions up to, and including, 3.1.9. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve metadata (name, image count, thumbnail URL) of private, draft, and password-protected galleries by enumerating gallery IDs.

The vulnerability identified as CVE-2025-15524 affects the Gallery by FooGallery plugin for WordPress, specifically targeting versions up to and including 3.1.9. This security flaw stems from a critical missing capability check within the ajax_get_gallery_info() function, which operates as a core component for retrieving gallery metadata through asynchronous requests. The absence of proper access controls creates a significant authorization bypass that undermines the plugin's security model and exposes sensitive gallery information to unauthorized users.
The technical implementation of this vulnerability resides in the ajax_get_gallery_info() function's failure to validate user permissions before returning gallery metadata. This function processes requests based on gallery IDs without verifying whether the requesting user possesses adequate privileges to access the specific gallery data. Attackers with Subscriber-level access or higher can exploit this weakness by simply enumerating valid gallery IDs through various means such as brute force techniques or by leveraging previously discovered gallery identifiers from public or semi-public sources. The function returns comprehensive metadata including gallery names, image counts, and thumbnail URLs, which collectively provide substantial information about private and protected content.
The operational impact of this vulnerability extends beyond simple information disclosure, as it enables attackers to gather detailed intelligence about gallery structures and content. Private galleries, draft collections, and password-protected albums become accessible to authenticated users who should not have visibility into such restricted content. This exposure creates potential risks for users who store sensitive or confidential information within these galleries, particularly in professional or organizational contexts where gallery content may contain proprietary data, client information, or other restricted materials. The vulnerability essentially allows for systematic enumeration and collection of metadata from protected gallery resources, providing attackers with valuable reconnaissance information.
From a cybersecurity perspective, this vulnerability aligns with CWE-284 (Improper Access Control) and represents a clear violation of the principle of least privilege. The flaw also maps to ATT&CK technique T1213.002 (Data from Information Repositories) as it enables unauthorized data extraction from a repository system. Organizations using the FooGallery plugin must address this issue immediately through plugin updates or implement compensating controls. The recommended mitigation strategy involves updating to a patched version of the plugin where proper capability checks have been implemented to verify user permissions before returning gallery metadata. Additionally, administrators should conduct thorough security audits of their WordPress installations to identify any other plugins with similar access control vulnerabilities that may require similar remediation efforts.
