#40401 closed defect (bug) (fixed)

Value of data-colname in wp-list-table is not escaped

Reported by: rellect's profile rellect Owned by: sergeybiryukov's profile SergeyBiryukov
Milestone: 5.8 Priority: normal
Severity: normal Version: 4.3
Component: Administration Keywords: has-patch commit

It looks like at some point the esc_attr() was removed in favor of wp_strip_all_tags

// Comments column uses HTML in the display name with screen reader text.
// Instead of using esc_attr(), we strip tags to get closer to a user-friendly string.
$data = 'data-colname="' . wp_strip_all_tags( $column_display_name ) . '"';

But wp_strip_all_tags does not escape the value, so wp_strip_all_tags should've been added as addition to esc_attr, and not as a replacement.

Thanks for the refresh, @audrasjb.

I notice a few other instances of wp_strip_all_tags() used without escaping. In the class-wp-screen file, for instance.
Should we handle those cases as well?
