Unauthenticated database disclosure via raw load-more parameters
Published Jul 20, 2026 · Updated Jul 20, 2026
SQL injection in Webnus Modern Events Calendar Lite and Pro before 7.34.0 allows remote attackers to read sensitive database data. The mec_list_load_more handler concatenates attacker-controlled atts[include] or atts[exclude] array values into post_id clauses and executes the query without preparation. The public AJAX action needs no account or user interaction, but the time-based oracle requires at least one published event and discloses database contents without demonstrated writes.
