CVE-2026-56272 Flowise CVE debrief

Who should care

Flowise administrators and security teams should assess exposure and prioritize upgrading to version 3.0.13 or later. Verify Flowise version and assess exposure to bcrypt password hashing risks. Review password hashing configurations to ensure sufficient salt rounds and consider compensating controls for exposed systems.

Why it matters

CVE-2026-56272 allows attackers to crack Flowise password hashes faster due to insufficient bcrypt salt rounds. Flowise administrators should verify their version, assess exposure, and upgrade to version 3.0.13 or later.

• Verify Flowise version and assess exposure to bcrypt password hashing risks
• Upgrade Flowise to version 3.0.13 or later to increase password hashing security
• Review password hashing configurations to ensure sufficient salt rounds

Technical summary

Flowise before 3.0.13 uses bcrypt with default salt rounds of 5, providing only 32 iterations instead of the OWASP-recommended minimum of 10 rounds. This allows attackers to crack password hashes approximately 30 times faster with modern GPU hardware, potentially compromising all user accounts in a database breach scenario. The source detail is limited; verify Flowise version and assess exposure to bcrypt password hashing risks. Review password hashing configurations to ensure sufficient salt rounds and consider compensating controls for exposed systems.

Defensive priority

Medium priority for Flowise deployments; verify and upgrade

Recommended defensive actions

• Verify Flowise version and assess exposure
• Upgrade Flowise to version 3.0.13 or later
• Review password hashing configurations
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review compensating controls for exposed systems while remediation is scheduled and verified
