CVE-2026-5554
Published: 05 April 2026
Summary
CVE-2026-5554 is a medium-severity Injection (CWE-74) vulnerability in Code Projects (inferred from references). 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 13.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2026-5554 is a SQL injection vulnerability affecting code-projects Concert Ticket Reservation System 1.0. The flaw resides in an unknown functionality of the file /ConcertTicketReservationSystem-master/process_search.php within the Parameter Handler component. It arises from improper handling of the 'searching' argument, allowing remote attackers to manipulate input and inject malicious SQL payloads. The vulnerability carries 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) and is associated with CWEs 74 (Improper Neutralization of Special Elements) and 89 (SQL Injection). It was published on 2026-04-05.
Remote attackers require no privileges or user interaction to exploit this vulnerability over the network with low complexity. Successful exploitation enables limited impacts: low confidentiality (e.g., partial data exposure), low integrity (e.g., minor unauthorized modifications), and low availability (e.g., minor denial of service). As a classic SQL injection, it could allow extraction or alteration of database contents depending on the backend schema and permissions.
Advisories and further details are available in referenced sources, including code-projects.org, a GitHub issue at github.com/Wzl731/test/issues/4, and VulDB entries at vuldb.com/submit/782874, vuldb.com/vuln/355324, and vuldb.com/vuln/355324/cti. No specific patch or mitigation steps are detailed in the core vulnerability disclosure.
The exploit has been publicly released and may be used in attacks, increasing the risk for unpatched instances of the affected system.
