HIGH 7.1

DescriptionCVE.org

Flowise before 3.1.3 contains an incomplete credential redaction vulnerability in the GET /api/v1/credentials/:id endpoint that returns decrypted secrets in plaintext. Authenticated users with credentials:view permission can retrieve sensitive data including database connection URLs with embedded passwords, cloud service account JSON with private keys, and API keys by calling this endpoint.

AnalysisAI

Incomplete credential redaction in Flowise before 3.1.3 exposes fully decrypted secrets via the authenticated GET /api/v1/credentials/:id endpoint, allowing any user with credentials:view permission to retrieve database connection URLs containing embedded passwords, Google Cloud service account JSON files with RSA private keys, and AWS access keys in plaintext. The root cause is a server-side redaction function that only masks schema fields declared with type 'password', leaving string-typed fields - routinely used for sensitive credential values - untouched in the plainDataObj API response. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid authenticated session in the target Flowise workspace with the credentials:view permission assigned to the user's role. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 7.1 (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N) is a reasonable representation of the direct flaw, but the effective blast radius is substantially higher because the confidentiality impact is not limited to Flowise itself. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated Flowise user with the credentials:view role enumerates credential IDs visible in their workspace UI, then issues a series of GET /api/v1/credentials/:id requests using their session token. Each response contains a plainDataObj field with fully decrypted values - a PostgreSQL connection string including username and password, a Google service account JSON blob with an RSA private key, or an AWS access key pair - which the attacker then uses to authenticate directly to the downstream cloud or database services. …
Remediation Upgrade Flowise to version 3.1.3 or later, the vendor-released patch confirmed by GHSA-rwrp-9823-p2xq (https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-rwrp-9823-p2xq) and the npm package. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, audit system logs for GET requests to /api/v1/credentials endpoints, identify all users with credentials:view permission, and immediately rotate all database passwords, AWS access keys, and cloud service account credentials that may have been exposed. …
