Open User Map contributor input permits cross-site scripting
Open User Map through 1.4.46 lets a Contributor supply attacker-controlled input that reaches a browser-executable output context without adequate neutralization. The payload can execute in the site's origin when another user views the crafted output. The Patchstack CNA record does not disclose whether the payload is reflected or stored, or identify the endpoint, field, parameter or rendering function.
