CVE-2022-23638

描述

### Impact SVG sanitizer library before version `0.15.0` did not remove HTML elements wrapped in a CDATA section. As a result, SVG content embedded in HTML (fetched as `text/html`) was susceptible to cross-site scripting. Plain SVG files (fetched as `image/svg+xml`) were not affected. ### Patches This issue is fixed in `0.15.0` and higher. ### Workarounds There is currently no workaround available without upgrading. ### For more information If you have any questions or comments about this advisory: * Open an issue in [Github](https://github.com/darylldoyle/svg-sanitizer/issues) * Email us at [daryll@enshrined.co.uk](mailto:daryll@enshrined.co.uk)
