Security readout for executives and security teams
Plain-English summary
CVE-2026-1613 affects the Wonka Slide WordPress plugin through version 1.3.3. A logged-in user with Contributor or higher privileges can store malicious script through a shortcode attribute. The script runs when someone views the affected page, which can expose user data or alter page behavior.
Executive priority
Treat as a moderate-priority WordPress plugin issue. Prioritize sites with public traffic, multiple content contributors, or weak account controls. If no vendor fix is available, reduce exposure by disabling the plugin or restricting author access.
Technical view
The issue is stored cross-site scripting in Wonka Slide’s `list_class` shortcode attribute, caused by insufficient input sanitization and output escaping. It is classified as CWE-79 with CVSS 6.4. Exploitation requires authenticated Contributor-level access or higher, but does not require user interaction beyond visiting injected content.
Likely exposure
Sites using the Wonka Slide WordPress plugin up to and including version 1.3.3 are potentially exposed, especially where Contributor accounts are granted to untrusted users. Exposure is lower on sites without the plugin or without low-privileged content authors.
Exploitation context
The source bundle does not show CISA KEV listing or confirmed active exploitation. The practical risk is insider, compromised author account, or multi-user WordPress site abuse leading to persistent script execution for page visitors.
Researcher notes
The description states all versions up to 1.3.3 are affected, while the provided affected metadata is sparse and lists default status as unaffected. No patch version is identified in the provided sources. Validation should focus on installed plugin version, role exposure, and stored shortcode content.
Mitigation direction
- Inventory WordPress sites for Wonka Slide installations and versions.
- Check vendor or WordPress plugin guidance for a fixed release.
- Update if a vendor-fixed version is available.
- Disable or remove the plugin if no safe version is available.
- Limit Contributor and higher roles to trusted users only.
- Review affected shortcode usage in existing posts and pages.
Validation and detection
- Confirm whether Wonka Slide is installed and enabled.
- Record the installed plugin version on each site.
- Identify users with Contributor, Author, Editor, or Administrator roles.
- Review pages using the Wonka Slide shortcode.
- Inspect `list_class` attributes for unexpected script-like content.
- Check WordPress audit logs for recent shortcode edits.

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.
