View on CVE.org

Published Nov 8, 2025 CVSS 3.1 · 4.3 Medium EPSS < 1% KEV · Not listed

Description

The Gallery Plugin for WordPress – Envira Photo Gallery plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the '/envira-convert/v1/bulk-convert' REST API endpoint in all versions up to, and including, 1.11.0. This makes it possible for authenticated attackers, with contributor-level access and above, to convert galleries to Envira galleries.

Analysis

Technical impact

The Envira Gallery plugin for WordPress has a missing capability check on the "/envira-convert/v1/bulk-convert" REST API endpoint, which allows any authenticated user with contributor-level access or higher to convert galleries into Envira galleries. This provides unauthorized modification of gallery data, affecting content integrity and potentially altering site appearance or navigation.

Affected Systems

All versions of the Envira Gallery – Image Photo Gallery, Albums, Video Gallery, Slideshows & More plugin up to and including 1.11.0 are affected. The vulnerability applies to the WordPress plugin delivered by smub, and impacts both the full and lite distributions as indicated by the reference paths.

Risk and Exploitability

The CVSS score of 4.3 indicates moderate severity; the EPSS score is below 1%, and the vulnerability is not listed in the CISA KEV catalog. The likely attack vector is authenticated access from a contributor or higher role, requiring nothing beyond normal WordPress credentials. Exploitation simply triggers the bulk convert endpoint, allowing the attacker to alter gallery content without further system compromise.
