CVE-2026-3357: CWE-502 Deserialization of Untrusted Data in IBM Langflow Desktop
CVE-2026-3357 is a high-severity vulnerability in IBM Langflow Desktop versions 1. 6. 0 through 1. 8. 2. It involves insecure deserialization of untrusted data in the FAISS component, which could allow an authenticated user to execute arbitrary code on the affected system. The vulnerability arises from an insecure default setting that permits this unsafe deserialization. There is no vendor advisory or patch information currently available for this vulnerability. The CVSS score is 8. 8, indicating a high impact on confidentiality, integrity, and availability.
AI Analysis
Technical Summary
IBM Langflow Desktop versions 1.6.0 through 1.8.2 contain a deserialization vulnerability (CWE-502) in the FAISS component due to an insecure default configuration. This flaw allows an authenticated user to execute arbitrary code by exploiting the deserialization of untrusted data. The vulnerability is tracked as CVE-2026-3357 with a CVSS 3.1 base score of 8.8, reflecting network attack vector, low attack complexity, required privileges, no user interaction, and high impact on confidentiality, integrity, and availability. No official patch or remediation guidance has been published by IBM as of the data provided.
Potential Impact
Successful exploitation of this vulnerability could lead to arbitrary code execution by an authenticated user, potentially compromising system confidentiality, integrity, and availability. This could allow attackers to execute malicious code with the privileges of the authenticated user, leading to significant system compromise.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider restricting access to the affected versions and monitor for any updates from IBM. No official mitigation or temporary fix has been provided by the vendor at this time.
