CVE-2026-1589 is a medium-severity Injection (CWE-74) vulnerability in Angeljudesuarez School Management System. Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 29.6th 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 SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-1589 is a SQL injection vulnerability in the itsourcecode School Management System 1.0, affecting an unknown function within the file /ramonsys/inquiry/index.php. The issue arises from improper handling of the txtsearch argument, allowing remote attackers to manipulate input and inject malicious SQL queries. Classified under CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection), it received a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), indicating high severity due to its network accessibility and low attack complexity. The vulnerability was published on 2026-01-29.
Unauthenticated remote attackers can exploit this vulnerability over the network without user interaction by crafting requests that manipulate the txtsearch parameter, potentially leading to limited impacts on confidentiality, integrity, and availability. Successful exploitation could allow extraction of sensitive data, modification of database contents, or disruption of service, though the unchanged scope limits broader system compromise.
Advisories and references, including the vendor site at https://itsourcecode.com/, a publicly available exploit file at https://mega.nz/file/DQUWSY7Y#CLcuhD1KE2s0VtEvYqH_PDCyhpGS0HDo_MKj9sheUPA, and VulDB entries at https://vuldb.com/?ctiid.343352, https://vuldb.com/?id.343352, and https://vuldb.com/?submit.740686, confirm the exploit's public disclosure and potential for utilization, but do not detail specific patches or mitigations in the available information. Security practitioners should monitor these sources for updates and apply input validation or upgrades where possible.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation and sanitization of the txtsearch input parameter to block malicious SQL syntax before it reaches the database.
Boundary protection devices can enforce input filtering or WAF rules that inspect and drop SQL-injection payloads targeting /ramonsys/inquiry/index.php.
Requires timely remediation of the identified flaw in the inquiry module so the vulnerable code path is removed or corrected.
