The /api/v1/chatflows/apikey/:apikey endpoint (whitelisted, accessible with API key auth only) returns all chatflows bound to the provided API key AND all chatflows across the entire system that have no API key assigned. This crosses workspace boundaries, allowing a user in Workspace A who has a valid API key to read the full configuration (including flowData, chatbotConfig, system prompts, and node configurations) of chatflows from Workspace B, Workspace C, and all other workspaces, as long as those chatflows have no API key assigned.
The controller at packages/server/src/controllers/chatflows/index.ts:90-107 validates the API key and calls the service:
const getChatflowByApiKey = async (req: Request, res: Response, next: NextFunction) => {
try {
const apikey = await apiKeyService.getApiKey(req.params.apikey)
if (\!apikey) {
return res.status(401).send("Unauthorized")
}
const apiResponse = await chatflowsService.getChatflowByApiKey(apikey.id, req.query.keyonly)
return res.json(apiResponse) // Returns full chatflow objects with flowData
} catch (error) {
next(error)
}
}
The service at packages/server/src/services/chatflows/index.ts:223-245 builds the database query:
const getChatflowByApiKey = async (apiKeyId: string, keyonly?: unknown): Promise<any> => {
const appServer = getRunningExpressApp()
let query = appServer.AppDataSource.getRepository(ChatFlow)
.createQueryBuilder("cf")
.where("cf.apikeyid = :apikeyid", { apikeyid: apiKeyId })
if (keyonly === undefined) {
// When keyonly is not set (default), also return ALL chatflows with no API key
query = query.orWhere("cf.apikeyid IS NULL").orWhere("cf.apikeyid = ''")
}
const dbResponse = await query.orderBy("cf.name", "ASC").getMany()
return dbResponse // Returns full ChatFlow entities including flowData
}
When keyonly is not provided as a query parameter (which is the default case), the query expands to include:
apikeyid IS NULL (any workspace, no workspace filter)apikeyid (any workspace, no workspace filter)There is NO workspaceId filter in this query. The response includes the full ChatFlow entity, which contains:
flowData - the complete workflow graph including system prompts, model names, internal URLs, custom codeRunning one of these products? Scan your site to see whether it exposes a vulnerable version.

textToSpeech and speechToText fields include credential IDs, which can be abused via the TTS generate endpoint.Add workspace scoping to the getChatflowByApiKey query by passing the API key workspace ID and filtering the OR clause:
// packages/server/src/services/chatflows/index.ts
const getChatflowByApiKey = async (apiKeyId: string, keyonly?: unknown, workspaceId?: string): Promise<any> => {
const appServer = getRunningExpressApp()
let query = appServer.AppDataSource.getRepository(ChatFlow)
.createQueryBuilder("cf")
.where("cf.apikeyid = :apikeyid", { apikeyid: apiKeyId })
if (keyonly === undefined && workspaceId) {
// Only include unprotected chatflows from the SAME workspace
query = query.orWhere(
"(cf.apikeyid IS NULL OR cf.apikeyid = :empty) AND cf.workspaceId = :workspaceId",
{ empty: "", workspaceId }
)
}
const dbResponse = await query.orderBy("cf.name", "ASC").getMany()
return dbResponse
