Package: wordpress
Version: 3.6.1+dfsg-1~deb7u2
Severity: normal
Tags: security upstream patch
Hi,
Upstream Wordpress 3.8.2 introduced a bug in bulk_edit_posts:
https://core.trac.wordpress.org/ticket/27792
It seems to me that cs27976_priv_esc backported the bug into
Wordpress 3.6, though I haven't tested in a running WP instance.
There was an incomplete fix committed as cs27991, that was reverted
and improved by cs28114. Combining these, I ended up with the attached
cs28114_bulk_edit_posts
Thanks.
