The package's only shipped content, strings.json, is presented as an i18n/translation resource bundle but its values are HTML/JavaScript XSS payloads rather than localized text. Multiple entries use `<img src=x onerror=...>` and `<svg onload=...>` handlers that invoke fetch() against the hardcoded endpoint https://notpismo.cloud/c, sending `document.domain` and `document.cookie` as query parameters. Any consumer application that renders these strings as HTML (the ordinary use of an i18n bundle in web UIs) will execute the injected script in the end-user's browser and transmit that user's session cookies and hosting domain to notpismo.cloud. The package name and framing as a translation resource are a cover for the payload; there is no legitimate localization content in the file.
