Summary

CVE-2026-5827 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 2.6th 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 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2026-5827 is a SQL injection vulnerability (CWE-74, CWE-89) affecting code-projects Simple IT Discussion Forum version 1.0. The flaw resides in an unknown function within the file /question-function.php, where manipulation of the 'content' argument enables SQL injection.

The vulnerability is remotely exploitable over the network with low attack complexity, requiring no privileges or user interaction (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L, base score 7.3). Unauthenticated remote attackers can initiate the attack to achieve limited impacts on confidentiality, integrity, and availability.

Advisories and references, including those from VulDB (vuldb.com/vuln/356274) and a GitHub issue (github.com/lonelyuan/vunls/issues/8), document the issue. The exploit has been disclosed publicly and may be used, with no patch details specified in the available information.

The vulnerability was published on 2026-04-09, and the exploit disclosure increases the risk of active exploitation against unpatched instances of the affected forum software.
