Summary

CVE-2026-5829 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 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2026-5829 is a SQL injection vulnerability (CWE-74, CWE-89) in code-projects Simple IT Discussion Forum version 1.0. The affected component is an unknown function within the file /pages/content.php, where manipulation of the post_id argument triggers the injection.

Remote attackers require no privileges (PR:N) and can exploit the vulnerability over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N), as indicated by its CVSS v3.1 base score of 7.3 (C:L/I:L/A:L/S:U). Successful exploitation allows limited impacts on confidentiality, integrity, and availability.

Advisories and details are available in references such as VulDB entries (vuldb.com/vuln/356276), a GitHub issue (github.com/lonelyuan/vunls/issues/6), and the project site (code-projects.org). The exploit has been publicly disclosed and may be utilized.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

SI-10 mandates validation and sanitization of the post_id input parameter to directly prevent SQL injection exploitation in /pages/content.php.

SI-2 Flaw Remediation good match
prevent

SI-2 requires timely remediation of the specific SQL injection flaw in Simple IT Discussion Forum 1.0 via patching or code correction.

SC-7 Boundary Protection partial match
prevent

SC-7 employs boundary protection such as web application firewalls to inspect and block malicious SQL injection payloads targeting the vulnerable post_id argument.
