CVE-2026-116010 francoisjacquet CVE debrief

Who should care

Defenders responsible for RosarioSIS installations, particularly those in educational institutions, should assess exposure and potential impact on student data. This includes IT personnel, system administrators, and cybersecurity teams who manage RosarioSIS and are responsible for ensuring the security and integrity of student records.

Why it matters

The missing authorization vulnerability in RosarioSIS before 12.9.1 allows authenticated teachers to modify student records, potentially impacting student data integrity.

• Verify teacher access controls to prevent unauthorized student data modifications
• Assess potential impact on student records and grades
• Monitor for suspicious activity on student data

Technical summary

The vulnerability allows authenticated teachers to write records for students outside their course period by supplying arbitrary student IDs, enabling modifications to referrals, eligibility codes, attendance, and final grades. This is a serious issue because it could allow teachers to alter student records without proper authorization, potentially impacting student data integrity. The vulnerability is in the RosarioSIS software before version 12.9.1, and it is essential for defenders to verify exposure and assess potential impact on student data.

Defensive priority

Defenders should prioritize verifying exposure and assessing potential impact on student data.

Recommended defensive actions

• Verify RosarioSIS version and assess exposure
• Restrict teacher access to student records
• Monitor for suspicious activity on student data
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and source item provide details on the vulnerability, affected versions, and potential impact. However, additional information on exploitation and remediation is limited. Further verification is needed to assess the vulnerability's impact and to identify potential mitigations. The CVE Program and other sources do not provide explicit evidence of exploitation or detailed remediation guidance.
