Summary

Full security review of the plugin's PHP:

  • No superglobal access ($_GET/$_POST/$_REQUEST/$_SERVER/$_COOKIE/$_FILES) anywhere in the codebase.
  • No dangerous functions (eval, exec, system, shell_exec, unserialize, extract, create_function, base64_decode, assert) anywhere.
  • No $wpdb usage or raw SQL — nothing to parameterize.
  • All dynamic output already escaped (the two get_block_wrapper_attributes()/wp_interactivity_data_wp_context() false-positives are documented with phpcs:ignore in the PHPCS PR in this batch).
  • The one gap: none of the plugin's directories (., Functions/, src/, src/blocks/, and each block folder) had the standard WordPress index.php stub, so a server that serves directory listings (Options +Indexes, or a misconfigured host) would expose the plugin's file structure. Added the standard stub to all 7 — new files only, no overlap with the other PRs in this batch.

Test Plan

  • php -l passes on all 7 new files
  • Manually verified each new file is a passive stub with no executable logic — zero behavioral change to the plugin

None of the plugin's directories had the standard WordPress
index.php stub, so if the server ever serves directory listings
(Options +Indexes, or a misconfigured host), the plugin's source
tree structure and filenames are exposed. No functional or SQL/XSS
vulnerabilities were found elsewhere in the codebase in this review:
no superglobal access, no dangerous functions (eval, exec,
unserialize, etc.), no raw $wpdb queries, and all dynamic output is
already escaped.
