CVE-2026-7874: CWE-338 Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in IBM Langflow OSS
IBM Langflow OSS 1.0.0 through 1.10.0 Langflow could allow disclosure of all stored credentials due to the use of a weak and reversible key derivation mechanism for encryption at rest.
AI Analysis
Technical Summary
CVE-2026-7874 affects IBM Langflow OSS versions 1.0.0 through 1.10.0. The product uses a weak and reversible key derivation mechanism for encrypting data at rest, which is a cryptographic weakness categorized under CWE-338. This vulnerability could lead to the disclosure of all stored credentials within the affected versions. The CVSS 3.1 score of 9.1 reflects high confidentiality and integrity impact, with no availability impact. There is no vendor-provided patch or remediation information available at this time, and no known exploits in the wild have been reported.
Potential Impact
An attacker can potentially disclose all stored credentials due to the weak cryptographic mechanism protecting data at rest. This compromises confidentiality and integrity of sensitive information stored by IBM Langflow OSS versions 1.0.0 through 1.10.0. The vulnerability does not affect availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider restricting access to affected systems and sensitive data. Monitor IBM advisories for updates on patches or mitigations.
