Deeper analysis

CVE-2026-30995 is a SQL injection vulnerability (CWE-89) affecting Slah CMS versions 1.5.0 and below. The issue resides in the 'id' parameter of the 'vereador_ver.php' endpoint, allowing malicious SQL queries to be injected and executed.

The vulnerability is exploitable remotely over the network (AV:N) with low attack complexity (AC:L), requiring no privileges (PR:N) or user interaction (UI:N), and has unchanged scope (S:U). Successful exploitation enables high-impact confidentiality breaches, such as unauthorized data extraction, alongside low impacts to integrity and availability, resulting in a CVSS v3.1 base score of 8.6.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Requires validation of the 'id' parameter in vereador_ver.php, directly preventing SQL injection by rejecting malicious inputs before they reach the database.

SI-2 Flaw Remediation good match
prevent

Mandates identification, reporting, and correction of the specific SQL injection flaw in Slah CMS v1.5.0 and below, eliminating the vulnerability through patching.

AC-6 Least Privilege partial match
prevent

Enforces least privilege on database accounts used by the application, limiting the scope of unauthorized data extraction even if SQL injection occurs.
