CSP: script-src-attr
The HTTP Content-Security-Policy (CSP)
script-src-attr directive specifies valid sources for
JavaScript inline event handlers. This includes only inline script event handlers like
onclick, but not URLs loaded directly into <script>
elements.
| CSP version | 3 |
|---|---|
| Directive type | Fetch directive |
default-src fallback |
Yes.
If this directive is absent, the user agent will look for the script-src directive, and if both of them are absent, fallback to default-src directive.
|
Syntax
One or more sources can be allowed for the script-src-attr policy:
Content-Security-Policy: script-src-attr <source>;
Content-Security-Policy: script-src-attr <source> <source>;
script-src-attr can be used in conjunction with script-src:
Content-Security-Policy: script-src <source>;
Content-Security-Policy: script-src-attr <source>;
Sources
<source> can be any one of the values listed in CSP Source Values.
Note that this same set of values can be used in all fetch directives (and a number of other directives).
Examples
Fallback to script-src
If script-src-attr is absent, User Agent falls back to
the script-src directive, and if that is absent as well, to
default-src.
