CVE-2026-4766: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in devrix Easy Image Gallery
The Easy Image Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Gallery shortcode post meta field in all versions up to, and including, 1.5.3. This is due to insufficient input sanitization and output escaping on user-supplied gallery shortcode values. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2026-4766 is a stored cross-site scripting vulnerability in the Easy Image Gallery WordPress plugin (versions up to and including 1.5.3). The flaw is due to improper neutralization of input in the Gallery shortcode post meta field, allowing authenticated users with Contributor-level privileges or higher to inject malicious scripts. These scripts execute in the context of other users viewing the injected pages, potentially leading to information disclosure or session hijacking. The vulnerability has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and partial impact on confidentiality and integrity.
Potential Impact
An attacker with Contributor-level access or higher can inject persistent malicious scripts into pages via the Gallery shortcode post meta field. These scripts execute in the browsers of users who view the affected pages, potentially leading to theft of sensitive information or unauthorized actions performed on behalf of users. The vulnerability does not impact availability. There are no known active exploits reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider removing or disabling the Easy Image Gallery plugin if possible. Monitor for updates from the vendor or plugin maintainers regarding patches or mitigations.
