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. Attackers can crack password hashes approximately 30 times faster with modern GPU hardware, potentially compromising all user accounts in a database breach scenario.

GHSA-x2g5-fvc2-gqvp — Flowise has Insufficient Password Salt Rounds

Affected: npm: flowise

### Description The default bcrypt salt rounds is set to 5, which is below the recommended minimum for security.

### Affected Code ``` export function getHash(value: string) { const salt = bcrypt.genSaltSync(parseInt(process.env.PASSWORD_SALT_HASH_ROUNDS || '5')) return bcrypt.hashSync(value, salt) } ```

### Evidence Using 5 salt rounds provides 2^5 = 32 iterations, which is far below the OWASP recommendation of 10 (2^10 = 1024 iterations) for bcrypt. This makes password hashes vulnerable to brute-force attacks with modern hardware.

### Impact Faster 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.

### Recommendation Increase 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.

### Notes The 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 breac…
