Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 46.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 AC-14 (Permitted Actions Without Identification or Authentication) and AC-3 (Access Enforcement).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 3 other techniques. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-14 Permitted Actions Without Identification or Authentication good match

prevent

Directly prohibits unauthenticated actions like reading, modifying, or deleting database contents through the vulnerable functionality.

IA-8 Identification and Authentication (Non-organizational Users) good match

prevent

Requires unique identification and authentication for non-organizational users, blocking unauthenticated remote attackers from exploiting the missing authentication.

AC-3 Access Enforcement good match

prevent

Enforces approved access authorizations, ensuring authentication is required before allowing database read, modify, or delete operations.

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 →

T1213.006 Databases Collection

Adversaries may leverage databases to mine valuable information.

attack.mitre.org →

T1485 Data Destruction Impact

Adversaries may destroy data and files on specific systems or in large numbers on a network to interrupt availability to systems, services, and network resources.

attack.mitre.org →

T1565.001 Stored Data Manipulation Impact

Adversaries may insert, delete, or manipulate data at rest in order to influence external outcomes or hide activity, thus threatening the integrity of the data.

Why these techniques?

Missing authentication enables unauthenticated remote exploitation of a public-facing application (T1190), granting arbitrary database read (T1213.006), modification (T1565.001), and deletion (T1485).

NVD Description

Agentflow developed by Flowring has a Missing Authentication vulnerability, allowing unauthenticated remote attackers to read, modify, and delete database contents by using a specific functionality.

Deeper analysisAI

CVE-2026-2096 is a Missing Authentication vulnerability (CWE-288) in Agentflow, a product developed by Flowring. Published on 2026-02-10, it enables unauthenticated remote attackers to read, modify, and delete database contents through a specific functionality. The vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its network accessibility, low attack complexity, and lack of required privileges or user interaction.

Unauthenticated attackers can exploit this vulnerability remotely over the network without any prerequisites. Successful exploitation grants full control over the database, allowing arbitrary read, modification, and deletion of contents, which could lead to complete data compromise, tampering, or destruction.
