From 7c51751774759568e22f031195675840d62ec39a Mon Sep 17 00:00:00 2001 From: Jason Crist Date: Mon, 25 Aug 2025 13:22:13 -0400 Subject: [PATCH] Fix #31: Add comprehensive capability checks for critical operations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Updated REST API permission callbacks to use proper custom capabilities - Added capability checks to all theme pattern modification methods - Enhanced security while maintaining backward compatibility by allowing both: - Specific pattern capabilities (edit_tbell_pattern_blocks, read_tbell_pattern_block) - General WordPress capabilities (edit_others_posts, edit_posts, edit_theme_options) Key security improvements: - read_permission_callback(): Now checks for edit_posts OR read_tbell_pattern_block - write_permission_callback(): Now checks for edit_others_posts OR edit_tbell_pattern_blocks - update_theme_pattern(): Now checks for edit_theme_options OR edit_others_posts - delete_theme_pattern(): Now checks for edit_theme_options OR edit_others_posts - update_theme_pattern_file(): Now checks for edit_theme_options OR edit_others_posts - update_user_pattern(): Now checks for edit_posts capability Updated test suite to ensure custom capabilities are properly set for testing. This provides defense-in-depth by requiring appropriate capabilities for: - Reading patterns (edit_posts minimum) - Modifying user patterns (edit_posts minimum) - Modifying theme patterns (edit_others_posts or edit_theme_options) - File system operations (edit_theme_options or edit_others_posts) All 44 unit tests passing with enhanced security. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- includes/class-pattern-builder-api.php | 15 +++--- includes/class-pattern-builder-controller.php | 38 +++++++++++++++ tests/php/test-pattern-builder-api.php | 47 +++++++++++++++++++ 3 files changed, 94 insertions(+), 6 deletions(-) diff --git a/includes/class-pattern-builder-api.php b/includes/class-pattern-builder-api.php index 0728dc9..76fbeb9 100644 --- a/includes/class-pattern-builder-api.php +++ b/includes/class-pattern-builder-api.php @@ -63,25 +63,27 @@ public function register_routes(): void { /** * Permission callback for read operations. - * Allows access to all logged-in users who can edit posts. + * Allows access to users who can read pattern blocks. * * @return bool True if the user can read patterns, false otherwise. */ public function read_permission_callback() { - return current_user_can( 'edit_posts' ); + // Allow reading for users who can edit posts or have specific pattern capabilities + return current_user_can( 'edit_posts' ) || current_user_can( 'read_tbell_pattern_block' ); } /** * Permission callback for write operations (PUT, POST, DELETE). - * Restricts access to administrators and editors only. + * Restricts access to users with proper pattern block capabilities. * Also verifies the REST API nonce for additional security. * * @param WP_REST_Request $request The REST request object. * @return bool|WP_Error True if the user can modify patterns, WP_Error otherwise. */ public function write_permission_callback( $request ) { - // First check if user has the required capability - if ( !
