Technical Analysis
CVE-2026-97680 describes an improper access control vulnerability (CWE-284) in IBM Langflow OSS versions 1.0.0 through 1.12.2. The issue resides in the vertex result caching subsystem, where insufficient access restrictions permit a remote attacker with valid authentication to obtain sensitive information or inject malicious data. The vulnerability is rated high severity with a CVSS 3.1 score of 8.3, reflecting high impact on confidentiality and integrity, and low attack complexity with no user interaction required.
Potential Impact
An attacker with valid credentials can exploit this vulnerability to access sensitive data or inject malicious content within the affected subsystem. This compromises confidentiality and integrity of the system and may lead to further exploitation or data breaches. Availability impact is low.
Mitigation Recommendations
No official patch or remediation details are provided in the available data. Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. Until a fix is available, restrict access to trusted authenticated users only and monitor for suspicious activity related to the vertex result caching subsystem.
