Authenticated SQL injection via unescaped tag fields
Published Apr 3, 2026 · Updated Apr 3, 2026
SQL injection in emlog 2.6.2 and earlier allows remote authenticated users to read and modify database data through tag editing. The updateTagName() method in include/model/tag_model.php concatenates tag fields into an UPDATE statement and relies only on addslashes() instead of parameter binding or database-aware escaping. Administrative access to tag management is required, and exploitation depends on database configurations in which backslash escaping is insufficient.
