CVE-2026-15099: XSS (CVSS 6.4)

Description

The Delicious Recipes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'steps' block attribute in versions up to, and including, 1.10.2. This is due to insufficient input sanitization and output escaping in the wrap_direction_text() function, which interpolates the user-supplied href value from nested link nodes ($node['props']['href']) directly into an anchor tag via sprintf() at line 1627 without esc_url() or any URL scheme validation. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts (including javascript: URIs) in pages that will execute whenever a user (such as an editor or administrator previewing the pending post) accesses an injected page and clicks the malicious link.
