CVE-2026-2247
HighSummary
SQL injection vulnerability in Clicldeu SaaS occurs during report generation. A remote authenticated attacker can send a malicious payload in the URL generated after downloading the student's report card in the 'Day-to-day' section from the mobile app. The session token in the URL does not expire, and unusual characters can be entered after the 'id_alu' parameter, enabling boolean-based blind and time-based blind SQLi.
Risk Assessment
An attacker could access confidential information in the database, compromising data confidentiality.
Recommendation
Update Clicldeu SaaS to a patched version immediately. Also implement input validation and use parameterized SQL queries.

Original NVD description (English source)
SQL injection vulnerability (SQLi) in Clicldeu SaaS, specifically in the generation of reports, which occurs when a previously authenticated remote attacker executes a malicious payload in the URL generated after downloading the student's report card in the ‘Day-to-day’ section from the mobile application. In the URL of the generated PDF, the session token used does not expire, so it remains valid for days after its generation, and unusual characters can be entered after the ‘id_alu’ parameter, resulting in two types of SQLi: boolean-based blind and time-based blind. Exploiting this vulnerability could allow an attacker to access confidential information in the database.
