This makes password hashes vulnerable to brute-force attacks with modern hardware.\n\n### Impact\nFaster password cracking - in the event of database compromise, attackers can crack password hashes significantly faster than with proper salt rounds, potentially compromising all user accounts.\n\n### Recommendation\nIncrease default PASSWORD_SALT_HASH_ROUNDS to at least 10 (recommended by OWASP). Consider using 12 for better security-performance balance. Document that higher values increase login time but improve security.\n\n### Notes\nThe default bcrypt salt rounds is 5 (line 6), which provides only 2^5=32 iterations. OWASP recommends minimum 10 rounds (1024 iterations) for bcrypt. While configurable via PASSWORD_SALT_HASH_ROUNDS env var, the default matters because: (1) most deployments use defaults, (2) existing password hashes at 5 rounds remain vulnerable even if later increased. With modern GPUs, 5 rounds allows ~300,000 hashes/second vs ~10,000/second at 10 rounds - a 30x difference in cracking speed. In a database breach scenario, all user passwords could be cracked significantly faster. The same weak default is used in resetPassword (account.service.ts:568). This is a cryptographic weakness with real-world impact on password security.\n\n**Detection Method:** Kolega.dev Deep Code Scan\n\n| Attribute | Value |\n|---|---|\n| Severity | Medium |\n| CWE | CWE-916 (Use of Password Hash With Insufficient Computational Effort) |\n| Location | packages/server/src/enterprise/utils/encryption.util.ts:5-7 |\n| Practical Exploitability | Medium |\n| Developer Approver | faizan@kolega.ai |","state":0,"publishedAt":"2026-03-05T21:54:31+00:00","modifiedAt":"2026-07-20T21:46:41.5527931+00:00","affected":[{"ecosystem":"npm","name":"flowise","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"3.0.13"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:N/A:N","score":null,"severity":null},{"system":"CVSS_V4","vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-x2g5-fvc2-gqvp","https://nvd.nist.gov/vuln/detail/CVE-2026-56272","https://github.com/FlowiseAI/Flowise/pull/5665","https://github.com/FlowiseAI/Flowise","https://www.vulncheck.com/advisories/flowise-insufficient-password-salt-rounds-in-bcrypt-hashing"],"sourceUrl":"https://github.com/advisories/GHSA-x2g5-fvc2-gqvp","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-x2g5-fvc2-gqvp","identifiers":["GHSA-x2g5-fvc2-gqvp","CVE-2026-56272"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
