Official description
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.What should I do about MAL-2026-14471?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
