CVE-2026-1939: Percent to Infograph <= 1.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes

The Percent to Infograph plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `percent_to_graph` shortcode in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping on user supplied attributes. 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.

Security readout for executives and security teams

Plain-English summary

CVE-2026-1939 affects the WordPress Percent to Infograph plugin up to version 1.0. A logged-in user with Contributor-level access or higher could save malicious script through shortcode attributes. That script could run when someone views the affected page, creating risk to site administrators and visitors.

Executive priority

Treat as a moderate-priority WordPress content security issue. Prioritize sites with many contributors, external authors, or untrusted content workflows. If the plugin is unnecessary, removal is the safest near-term action.

Technical view

The vulnerability is stored cross-site scripting in the `percent_to_graph` shortcode. Sources cite insufficient sanitization and output escaping of user-supplied shortcode attributes. CVSS 3.1 is 6.4, with low privileges required, network attack vector, changed scope, and low confidentiality and integrity impact.

Likely exposure

Exposure is limited to WordPress sites using Percent to Infograph version 1.0 or earlier and allowing Contributor-level or higher users to create content containing the vulnerable shortcode.

Exploitation context

The CVE record does not indicate known active exploitation, and it is not listed as KEV in the provided bundle. Exploitation requires an authenticated WordPress account with Contributor-level access or higher.

Researcher notes

Public references point to the shortcode handler in the plugin source and version 1.0 tag. The vulnerability is CWE-79 stored XSS through shortcode attributes. No public source in the bundle names a patched version or confirms exploitation in the wild.

Mitigation direction

  • Inventory WordPress sites for the Percent to Infograph plugin.
  • If installed at version 1.0 or earlier, check vendor or WordPress plugin guidance.
  • Disable or remove the plugin if it is not required.
  • Restrict Contributor-level access to trusted users only.
  • Review content workflows for shortcode use by lower-privileged users.

Validation and detection

  • Confirm whether the plugin is installed and active.
  • Record the installed plugin version on each WordPress site.
  • Review pages and posts using the `percent_to_graph` shortcode.
  • Check which users have Contributor, Author, Editor, or Administrator roles.
  • Monitor vendor, Wordfence, and WordPress plugin sources for remediation status.
