CVE-2025-4591

Status: DeferredMedium (6.4)—

The Weluka Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'weluka-map' shortcode in all versions up to, and including, 1.0.3 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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
