| Title | LockerProject Locker <=0.1.0 Reflected XSS |
|---|
| Description | The id parameter from req.params.id is directly concatenated into the error response at line 552 (res.send(id + " failed verification :(", 500)) without any sanitization or encoding. The PoC confirms the XSS payload <SvG oNlOAD=alert("zast-xss")> is reflected verbatim in the response, allowing arbitrary JavaScript execution in a victim's browser. |
