CVE-2026-1302: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in shahinurislam Meta-box GalleryMeta
The Meta-box GalleryMeta plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 3.0.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with editor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
AI Analysis
Technical Summary
CVE-2026-1302 is a stored cross-site scripting vulnerability in the Meta-box GalleryMeta plugin for WordPress. The issue is due to improper neutralization of input during web page generation (CWE-79), allowing authenticated users with editor or higher privileges to inject arbitrary scripts via admin settings. This vulnerability affects all versions up to and including 3.0.1 and is limited to multi-site installations or those with unfiltered_html disabled. The CVSS 3.1 vector indicates network attack vector, high attack complexity, high privileges required, no user interaction, and impacts confidentiality and integrity with no availability impact.
Potential Impact
An attacker with editor-level or higher privileges can inject persistent malicious scripts into pages, which execute when other users view those pages. This can lead to unauthorized actions or data exposure limited to confidentiality and integrity impacts. The vulnerability does not affect single-site installations or those with unfiltered_html enabled. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict editor-level permissions carefully and consider disabling the Meta-box GalleryMeta plugin in multi-site environments or where unfiltered_html is disabled. Monitor for updates from the plugin vendor regarding patches or official mitigations.
