Security readout for executives and security teams
Plain-English summary
Older Jannah WordPress theme versions could reflect attacker-controlled input into a page without proper sanitization. If a logged-in user follows a crafted link, malicious script could run in their browser under the affected site’s context.
Executive priority
Treat as a routine but real web application risk. Prioritize internet-facing WordPress sites, especially those with administrator activity, because successful XSS can support credential theft, session abuse, or malicious site changes.
Technical view
CVE-2021-24364 is a CWE-79 reflected XSS in Jannah before 5.4.4. The options JSON parameter in the tie_get_user_weather AJAX action was not properly sanitized before being output back to the page.
Likely exposure
Public WordPress sites using the TieLabs Jannah theme before 5.4.4 are the likely exposure. Sites not using Jannah, or already on a fixed version, are not indicated as affected by the supplied sources.
Exploitation context
The source bundle provides no evidence of active exploitation, and KEV is false. Reflected XSS usually depends on getting a victim to open a crafted request, with higher business risk if administrators or editors are targeted.
Researcher notes
The supplied record lacks CVSS details and does not include exploit evidence. The clearest technical detail is unsanitized reflection of the options JSON parameter in tie_get_user_weather, affecting Jannah before 5.4.4.
Mitigation direction
- Update Jannah to version 5.4.4 or later where available.
- Check TieLabs or WPScan guidance for any additional vendor-specific remediation.
- Reduce exposure of unused WordPress themes and plugins.
- Use WAF rules as temporary defense, not as a replacement for updating.
Validation and detection
- Inventory WordPress sites using the Jannah theme.
- Confirm installed Jannah versions are 5.4.4 or later.
- Review logs for requests to the tie_get_user_weather AJAX action.
- Use only benign markers when validating output handling.

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.
