Attack Vectors

CVE-2026-25363 is a Medium-severity missing-authorization issue (CVSS 4.3, vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N) affecting Gallery by FooGallery (FooGallery) for WordPress (plugin slug: foogallery) in versions up to and including 3.1.11.

The key business risk is that this can be exploited remotely by an authenticated user with contributor-level access (or higher). No user interaction is required, which can make abuse harder to detect if an account is compromised or a low-privileged internal account is misused.

Security Weakness

This vulnerability is caused by a missing capability check on a plugin function in FooGallery versions up to 3.1.11. In plain terms, the plugin does not consistently verify whether the logged-in user is actually authorized to perform a specific action before allowing it.

While the published summary does not specify the exact unauthorized action, the underlying issue is a common governance/control gap: roles and permissions are not being enforced as expected. That increases exposure when accounts are shared, when contractor access persists longer than intended, or when a low-privilege account is taken over via phishing or credential reuse.

Technical or Business Impacts

The CVSS impact rating indicates limited integrity impact (and no stated confidentiality or availability impact). Practically, that means an authenticated attacker could potentially trigger an unauthorized change within the WordPress environment where FooGallery is used, depending on how your site is configured and how that affected function is used operationally.

For marketing leaders and executives, the most likely business consequences include loss of content integrity (unexpected or unapproved site changes), brand and trust risk (customers seeing incorrect or altered content), and compliance/process risk if your organization relies on defined approval workflows for publishing or asset management.

Remediation: update Gallery by FooGallery (FooGallery) to version 3.1.13 or newer patched version as recommended by the vendor/community intelligence source. Source reference: Wordfence vulnerability record.
