What is CVE-2026-8354?
The Gum Addon for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'pop_tag' parameter in all versions up to, and including, 1.3.15 due to insufficient input sanitization and output escaping. 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 Score Explained
CVSS 6.4 is Medium severity. Exploitation usually requires some specific conditions (local access, user interaction, or a particular config). Still worth patching in your next maintenance window.
EPSS Exploitation Probability
EPSS 0.2% — low probability of active exploitation. Can be handled in normal patch cycles.
