CVE-2023-6924: Photo Gallery by 10Web <= 1.8.18 - Authenticated (Administrator+) Stored Cross-Site Scripting via Widget

The Photo Gallery by 10Web plugin for WordPress is vulnerable to Stored Cross-Site Scripting via widgets in versions up to, and including, 1.8.18 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with administrator-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. It can also be exploited with a contributor-level permission with a page builder plugin.

Security readout for executives and security teams

Plain-English summary

This is a stored cross-site scripting issue in the WordPress Photo Gallery by 10Web plugin through version 1.8.18. A trusted admin, or in some setups a contributor using a page builder, could save script content in gallery widgets that runs for later visitors to that page.

Executive priority

Treat this as a medium-priority hygiene fix unless the affected WordPress site has many delegated editors or sensitive authenticated users. The main concern is stored script execution on public pages, not unauthenticated takeover.

Technical view

CVE-2023-6924 is CWE-79 caused by insufficient sanitization and output escaping of widget attributes in Photo Gallery by 10Web. The cited vulnerable areas include Widget.php, WidgetSlideshow.php, and WidgetTags.php in version 1.8.18. CVSS is 4.4 with high privileges and high attack complexity.

Likely exposure

Exposure is limited to WordPress sites running Photo Gallery by 10Web version 1.8.18 or earlier, especially where widget editing or page-builder access is delegated beyond fully trusted administrators.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Practical exploitation requires authenticated access with administrator-level permissions, or contributor-level access when combined with a page builder plugin.

Researcher notes

The strongest evidence is the Wordfence record, CVE metadata, vulnerable widget source references, and WordPress Trac changeset 3013021. The bundle does not provide exploit telemetry, a KEV entry, or detailed deployment-specific prerequisites beyond roles and page-builder interaction.

Mitigation direction

  • Upgrade Photo Gallery by 10Web beyond version 1.8.18 using vendor guidance.
  • Restrict widget and page-builder editing to trusted administrators only.
  • Review existing gallery widgets for unexpected scripts or suspicious attributes.
  • Remove unnecessary contributor access to page-building capabilities.
  • Check vendor advisories before applying compensating controls.

Validation and detection

  • Inventory WordPress sites using Photo Gallery by 10Web.
  • Confirm installed plugin versions are newer than 1.8.18.
  • Identify pages using gallery, slideshow, or tag widgets.
  • Review role assignments for admin, contributor, and page-builder access.
  • Confirm the patched code escapes widget attribute output.
