CVE-2026-1551
Published: 29 January 2026
Summary
CVE-2026-1551 is a medium-severity Injection (CWE-74) vulnerability in Angeljudesuarez School Management System. Its CVSS base score is 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 28.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-6 (Least Privilege).
Deeper analysis
CVE-2026-1551 is a SQL injection vulnerability in the itsourcecode School Management System 1.0, affecting an unknown part of the file /ramonsys/course/controller.php. The flaw arises from improper handling of the 'ID' argument, allowing remote attackers to manipulate input and execute arbitrary SQL queries. It has a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) and is associated with CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection).
The vulnerability can be exploited remotely by attackers with low privileges, such as authenticated users, requiring no user interaction and low attack complexity. Successful exploitation enables limited impacts on confidentiality, integrity, and availability, potentially allowing unauthorized access to, modification of, or disruption of database contents through injected SQL commands.
Advisories are available via VulDB entries (ctiid.343247, id.343247, submit.740644) and the vendor site at itsourcecode.com, but no specific patch or mitigation details are detailed in the published information. A public exploit is available on mega.nz (file/6cVwiA5A#BVwaxWlfeQCkkpHnuxPiMDZVb5qcYrsI6ftqdm_8mGk), increasing the risk of real-world attacks.
