Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.
Mitigation guidance is detailed in advisories from the Flowring forum at https://forum.flowring.com/post/view?bid=72&id=45611&tpg=1&ppg=1&sty=1#45939 and TWCERT at https://www.twcert.org.tw/en/cp-139-10700-3534d-2.html and https://www.twcert.org.tw/tw/cp-132-10699-49c0b-1.html. Security practitioners should consult these sources for patches, workarounds, or configuration changes to address the issue.

Mitigating Controls (NIST 800-53 r5) AI
Requires a tamperproof, always-invoked reference monitor that structurally blocks bypass via any alternate path.
Enforces authorization checks on every logical access path, eliminating unauthenticated alternate channels.
Mandates unique identification and authentication for all organizational users, covering the primary authentication requirement.
Controls all external and key internal interfaces, reducing the chance of unauthenticated alternate channels.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Requiring authentication on every channel and path directly eliminates alternate-path bypasses.
Enforcing authorizations and least privilege across all access vectors prevents unauthenticated alternate paths.
Protecting networks and environments from unauthorized logical access blocks bypass via undocumented channels.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing can detect alternate-path bypasses but does not prevent them in production.
Secure authentication control directly mitigates bypass by requiring strong, consistent authentication on all paths.
Access control policy directly addresses alternate authentication paths by requiring all channels to enforce authentication.
Authentication information management ensures credentials and mechanisms are consistently applied across all access paths.
Access rights provisioning and review prevent bypass via unmonitored or alternate channels.
Privileged access rights control reduces risk of bypass through elevated or alternate paths.
