from the announcement:
> These minor releases include 3 security fixes following the security policy:
>
> - html/template: improper sanitization of CSS values
>
> Angle brackets (`<>`) were not considered dangerous characters when inserted
> into CSS contexts. Templates containing multiple actions separated by a '/'
> character could result in unexpectedly closing the CSS context and allowing
> for injection of unexpected HMTL, if executed with untrusted input.
>
> Thanks to Juho Nurminen of Mattermost for reporting this issue.
>
> This is CVE-2023-24539 and Go issue https://go.dev/issue/59720.
>
> - html/template: improper handling of JavaScript whitespace
>
> Not all valid JavaScript whitespace characters were considered to be
> whitespace. Templates containing whitespace characters outside of the character
> set "\t\n\f\r\u0020\u2028\u2029" in JavaScript contexts that also contain
> actions may not be properly sanitized during execution.
>
> Thanks to Juho Nurminen of Mattermost for reporting this issue.
>
> This is CVE-2023-24540 and Go issue https://go.dev/issue/59721.
>
> - html/template: improper handling of empty HTML attributes
>
> Templates containing actions in unquoted HTML attributes (e.g. "attr={{.}}")
> executed with empty input could result in output that would have unexpected
> results when parsed due to HTML normalization rules. This may allow injection
> of arbitrary attributes into tags.
>
> Thanks to Juho Nurminen of Mattermost for reporting this issue.
>
> This is CVE-2023-29400 and Go issue https://go.dev/issue/59722.
