Summary

CVE-2026-30711 is a high-severity SQL Injection (CWE-89) vulnerability in Purrfect (inferred from references). Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 11.7th 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).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Requires validation of untrusted HTTP inputs like Referer and User-Agent headers before incorporation into SQL queries, directly preventing SQL injection exploitation in session.inc.php.

SI-2 Flaw Remediation good match

prevent

Mandates timely remediation of identified flaws such as the SQL injection vulnerabilities in Devome GRR v4.5.0 to eliminate the root cause.

RA-5 Vulnerability Monitoring and Scanning partial match

detect

Vulnerability scanning of the web application would identify SQL injection flaws in session.inc.php via HTTP headers during periodic assessments.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

attack.mitre.org →

T1068 Exploitation for Privilege Escalation Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

attack.mitre.org →

Why these techniques?

Authenticated SQL injection (CWE-89) in web app directly enables remote exploitation of public-facing applications (T1190) and allows low-privileged authenticated users to achieve arbitrary DB access for privilege escalation (T1068).

NVD Description

Devome GRR v4.5.0 was discovered to contain multiple authenticated SQL injection vulnerabilities in the include/session.inc.php file via the referer and user-agent.

Deeper analysisAI

CVE-2026-30711 is a set of multiple authenticated SQL injection vulnerabilities (CWE-89) in Devome GRR version 4.5.0. The flaws reside in the include/session.inc.php file and are exploitable via manipulation of the Referer and User-Agent HTTP headers. Published on 2026-03-19, the vulnerability carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact.

An authenticated attacker with low privileges (PR:L) can exploit these SQL injections remotely over the network (AV:N) with low attack complexity (AC:L) and no user interaction required (UI:N). Exploitation enables high confidentiality, integrity, and availability impacts (C:H/I:H/A:H), potentially allowing arbitrary SQL query execution, data exfiltration, modification, or denial of service within the application's database.
