Fix: Ensure wp_kses_post() receives string in wp_add_id3_tag_data() #8901
Conversation
…ta() The wp_add_id3_tag_data() function was passing potentially non-string values to wp_kses_post(), which expects string input only. This change adds type checking and conversion to ensure all values are properly converted to strings before sanitization. - Add type checking for ID3 metadata values - Convert array values to space-separated strings - Cast non-string values to strings - Maintain existing sanitization and security measures
