CVE-2026-3011
MediumCVSS 6.4Summary
The Recipe Card Blocks Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) via the recipe block's 'summary' and 'notes' attributes in all versions up to and including 3.4.13. This is due to the 'WPZOOM_Helpers::deserialize_block_attributes' method converting unicode-encoded sequences back into HTML characters after sanitization has already been applied.
Risk Assessment
Authenticated attackers with Author-level access and above can inject arbitrary web scripts that execute whenever a user accesses the published post or the print view of an injected recipe. This poses a risk of data theft or session hijacking.
Recommendation
It is recommended to update the plugin to the latest version to mitigate this vulnerability. Additionally, conducting a security audit of existing content to detect potential script injections is advisable.
Original NVD description (English source)
The Recipe Card Blocks Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the recipe block's 'summary' and 'notes' attributes in all versions up to, and including, 3.4.13. This is due to the 'WPZOOM_Helpers::deserialize_block_attributes' method converting unicode-encoded sequences back into HTML characters after sanitization has already been applied. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that execute whenever a user accesses the published post or the print view of an injected recipe.
