CyberRota Analysis

AI-Generated

Flowise versions prior to 3.1.4 are vulnerable due to a broken access control issue in the GET /api/v1/organizationuser endpoint, allowing authenticated organization members to access the organization owner's full user record, including bcrypt password hashes and temporary tokens. This vulnerability poses a significant risk as it enables attackers to perform offline cracking of credential hashes, potentially leading to account takeover of the highest-privileged account. Organizations using affected versions should prioritize patching to mitigate the risk of unauthorized access and account compromise.
