CVE-2026-0699
Published: 08 January 2026
Summary
CVE-2026-0699 is a medium-severity Injection (CWE-74) vulnerability in Carmelo Intern Membership Management System. Its CVSS base score is 5.1 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 5.1th 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-3 (Access Enforcement).
Deeper analysis
CVE-2026-0699 is a SQL injection vulnerability in the Intern Membership Management System version 1.0 hosted on code-projects.org. The flaw resides in an unknown function within the file /intern/admin/edit_activity.php, where manipulation of the activity_id argument triggers the injection. It is classified under CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection), with a CVSS v3.1 base score of 4.7 (AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L).
Remote exploitation is possible for attackers who possess high privileges, such as authenticated administrative users, given the network accessibility, low attack complexity, and lack of required user interaction. Successful exploitation enables limited impacts: low-level disclosure of sensitive information (C:L), minor modification of data or configuration (I:L), and partial denial of service (A:L), all within the unchanged security scope.
VulDB advisories (ctiid.339976, id.339976, submit.733000) detail the vulnerability, and a proof-of-concept exploit has been publicly disclosed on GitHub, demonstrating SQL injection via the activity.php endpoint in the Intern Membership Management System. No patches or specific mitigation steps are outlined in the provided references.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation and neutralization of untrusted input such as the activity_id parameter before it is used in SQL statements, blocking the CWE-89 injection.
Restricts the high-privilege administrative accounts that can reach /intern/admin/edit_activity.php, reducing the population able to supply the malicious activity_id.
Enforces access-control policy on the edit_activity.php endpoint so that only explicitly authorized subjects may invoke the vulnerable function.
