Recommendations At the moment, there ...

Security Bulletin: Weak Cryptographic Key Derivation Exposed All Stored Credentials

Summary A critical vulnerability in the credential encryption system allowed attackers to decrypt all stored API keys, database passwords, and OAuth tokens. The system used Python's non-cryptographic Mersenne Twister PRNG seeded with the SECRETKEY to derive Fernet encryption keys for credentials...

Security Bulletin: Flow Validation Bypass via Empty Component Type Field

Summary A vulnerability in flow validation logic allowed attackers to bypass custom component restrictions by submitting flow nodes with empty or missing type fields. When custom components were disabled, the validator silently skipped nodes lacking a type value instead of blocking them, enabling...

Security Bulletin: Insecure Deserialization in Redis Cache Backend

Summary A deserialization vulnerability was identified in the Redis cache service that could allow attackers with network access to the Redis instance to execute arbitrary code. The cache service used dill.loads to deserialize cached values without integrity verification, enabling attackers to...

Security Bulletin: Code Injection Vulnerability in Code Validation Endpoint

Summary A code injection vulnerability was identified in the code validation endpoint that allowed authenticated users to execute arbitrary code on the server. The vulnerability existed in the validation logic which compiled and executed function definitions to check for import errors. Attackers...
