What is CVE-2026-8207?

Versions of Gibbon prior to v30.0.01 are susceptible to an authenticated SQL injection vulnerability. This flaw arises from the exploitation of the tracking and graphing feature, which is embedded within the platform. Attackers with Teacher-level privileges or higher can manipulate SQL queries, potentially leading to unauthorized access and modification of the underlying database. Successful exploits could enable unintended read and write operations, posing significant risks to data integrity and confidentiality. It is essential for users running Gibbon to upgrade to the latest version to mitigate this security risk.
