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.
