Administrator-level stored XSS via unescaped output
Published Apr 7, 2023 · Updated Apr 28, 2026
Stored XSS in Marcel Pol Zeno Font Resizer 1.7.9 and earlier allows remote authenticated users to inject script via unspecified vectors. Neither the CNA record nor the upstream 1.8.0 changelog identifies the affected setting or output path; the release states only that it escapes more output. Administrator access is required to store the payload, and user interaction is required for the script to execute in another browser context.
