savg-sanitizer is a PHP SVG/XML sanitizer. Prior to version 0.22.0, the sanitization logic in the cleanXlinkHrefs method only searches for lower-case attribute name, which allows to by-pass the isHrefSafeValue check. As a result this allows cross-site scripting or linking to external domains. This issue has been patched in version 0.22.0.

svg-sanitizer is a SVG/XML sanitizer written in PHP. A cross-site scripting vulnerability impacts all users of the `svg-sanitizer` library prior to version 0.15.0. This issue is fixed in version 0.15.0. There is currently no workaround available.

It is possible to bypass enshrined/svg-sanitize before 0.13.1 using the "xlink:href" attribute due to mishandling of the xlink namespace by the sanitizer.

darylldoyle svg-sanitizer before 0.12.0 mishandles script and data values in attributes, as demonstrated by unexpected whitespace such as in the javascript	:alert substring.
