CVE-2026-15790 (GCVE-0-2026-15790)
Vulnerability from cvelistv5
Published

CWE
  • CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Summary
The Youtube Showcase plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 4.0.4 via the 'emd_mb_meta' shortcode. This is due to insufficient input sanitization and output escaping on attachment titles referenced by the shortcode's image field: EMD_MB_Helper::image_info() returns the attachment's raw post_title, and EMD_MB_Helper::shortcode() interpolates it into title="%s" HTML attributes via sprintf() without esc_attr(). This makes it possible for authenticated attackers, with author-level access and above (upload_files capability required to create the attachment, edit_posts/publish_posts to embed the shortcode), to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

CVE-2026-12923 (GCVE-0-2026-12923)
Vulnerability from cvelistv5
Published
2026-07-01 03:43
Modified
2026-07-01 10:32
CWE
  • CWE-98 - Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion')
Summary
The Youtube Showcase plugin for WordPress is vulnerable to Arbitrary Function Call in versions up to and including 4.0.3. This is due to insufficient validation of the 'path' parameter in the emd_delete_file() AJAX handler in includes/common-functions.php. The user-supplied value is passed through sanitize_text_field(), has its trailing '_PLUGIN_DIR' substring stripped, and is then invoked as a PHP function name with no arguments via `$sess_name()`. The handler is gated only by a nonce — no current_user_can() check is present — and the nonce is emitted on any front-end page that renders a form shortcode containing file fields. This makes it possible for authenticated attackers, with Subscriber-level access and above, to invoke arbitrary zero-argument PHP functions (such as phpinfo, phpversion, get_defined_vars, error_get_last), resulting in sensitive information disclosure and potential further compromise depending on the functions available in the environment.
