Readycheck to confirm it

Teclib GLPI <= 9.3.3 exposes a script (/scripts/unlock_tasks.php) that incorrectly sanitizes user controlled data before using it in SQL queries. Thus, an attacker could abuse the affected feature to alter the semantic original SQL query and retrieve database records.

Impact

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary SQL queries, potentially leading to unauthorized access, data leakage, or data manipulation.

Fix

Upgrade to a patched version of Teclib GLPI (9.3.4 or later) to mitigate this vulnerability.
