CVE-2023-48765Network attack vector

Stored XSS via unescaped shortcode link attribute

Published Dec 15, 2023 · Updated Apr 28, 2026

Stored XSS in Till Krüss Email Address Encoder 1.0.22 and earlier allows remote authenticated users to inject scripts through a shortcode attribute. The eae_shortcode handler neither sanitizes the user-supplied link attribute sufficiently nor escapes it before rendering the stored post. Contributor-level access is required to create the payload, and the script runs when another user views the affected page.
