CVE-2026-82865Public exploitNetwork attack vector

JavaScript execution via unsanitized i18n label HTML

Published Aug 31, 2026 · Updated Aug 31, 2026

Cross-site scripting in @pdfme/schemas before 5.5.10 allows remote authenticated users to execute JavaScript through label overrides. The multiVariableText property panel concatenates unescaped i18n dictionary values and assigns the result to innerHTML in propPanel.ts. Exploitation requires control of options.labels and a user who opens the Designer and selects a field with no variable placeholders; the script runs in the embedding application's origin.
