CVE-2026-34788 emlog CVE debrief

CVE-2026-34788 is a SQL injection vulnerability in Emlog, a popular open-source website building system. This vulnerability affects versions 2.6.2 and prior. The issue lies in the updateTagName() function located in include/model/tag_model.php at line 168. Here, user input is directly interpolated into the SQL query string without proper sanitization or parameterized queries. Specifically, the function fails to utilize $this->db->escape_string() for input validation, rendering it susceptible to SQL injection attacks. At the time of publication, no patches are available, emphasizing the urgency for users to apply necessary mitigations or updates.
