Security readout for executives and security teams
Plain-English summary
This is a stored cross-site scripting issue in a WordPress plugin. A logged-in user with Contributor-level access or higher could place malicious script content through the plugin shortcode. That script can run when someone views the affected page, creating account, session, or content-integrity risk.
Executive priority
Treat this as a medium-priority web content risk. It is most urgent for publishing sites with many contributors, shared accounts, or weak account governance. Absence of KEV evidence lowers emergency urgency.
Technical view
CVE-2024-13575 is CWE-79 in Web Stories Enhancer – Level Up Your Web Stories through version 1.3. The issue is insufficient sanitization and output escaping of user-supplied attributes in the web_stories_enhancer shortcode. CVSS is 6.4 with low attack complexity and required low privileges.
Likely exposure
Exposure is limited to WordPress sites using Web Stories Enhancer – Level Up Your Web Stories version 1.3 or earlier, especially where Contributor or higher accounts are granted broadly or are externally managed.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation. Abuse requires authenticated Contributor-level access or higher, but the result is stored and can execute for later visitors without further attacker interaction.
Researcher notes
The key evidence is the Wordfence advisory, CVE record, shortcode source reference, and WordPress Trac changeset. The bundle does not provide proof of exploitation or detailed remediation text, so remediation should follow vendor guidance.
Mitigation direction
- Inventory sites for the affected WordPress plugin and version.
- Update the plugin according to vendor or WordPress plugin guidance.
- Restrict Contributor-level and higher access to trusted accounts only.
- Disable the plugin if it cannot be updated promptly.
- Review recent content edits by Contributor-level accounts and above.
Validation and detection
- Confirm whether the plugin is installed and active on each WordPress site.
- Verify the deployed version is not 1.3 or earlier.
- Identify pages or posts using the web_stories_enhancer shortcode.
- Review shortcode usage for unexpected script-like attributes or suspicious edits.
- Confirm Contributor-level accounts are legitimate and still required.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
