Severity: HIGH (CVSS ~7.5)
Type: CWE-200 (Exposure of Sensitive Information)
File: packages/server/src/services/credentials/index.ts:62-71
Description: When credentials are fetched with a credentialName filter parameter, the encryptedData field is NOT stripped from the response. The code properly omits encryptedData when NO filter is used (line 102) but fails to do so when a filter IS used (lines 62-63, 70-71).
Credential Data Leak
Evidence:
// Lines 62-63: WITH filter - encryptedData LEAKED
const credentials = await appServer.AppDataSource.getRepository(Credential).findBy(searchOptions)
dbResponse.push(...credentials) // encryptedData NOT removed!
// Lines 100-102: WITHOUT filter - encryptedData properly omitted
for (const credential of credentials) {
dbResponse.push(omit(credential, ['encryptedData'])) // Correctly omitted
}
Impact: Authenticated users can extract encrypted credential data (API keys, passwords, tokens for services like OpenAI, AWS, etc.). Combined with access to the encryption key file (~/.flowise/encryption.key written with default permissions), this enables full credential theft.
Reproduction:
curl https://TARGET/api/v1/credentials?credentialName=openAIApi \
-H "Authorization: Bearer API_KEY"
# Response includes encryptedData field with AES-encrypted credentials
