Async Javascript: urgent update available

by

There’s an update for Async Javascript that needs your urgent attention. Update asap!
[Update] I was warned by WordFence about a vulnerability in Async JavaScript that was being actively exploited. Based on their input I updated the plugin to fix the bug. WordFence in the meantime published a post about this and other affected plugins and with regard to AsyncJS writes:

Async JavaScript’s settings are modified via calls to wp-admin/admin-ajax.php with the action aj_steps. This AJAX action is registered only for authenticated users, but no capabilities checks are made. Because of this, low-privilege users including Subscribers can modify the plugin’s settings.
Similar to Flexible Checkout Fields above, certain setting values can be injected with a crafted payload to execute malicious JavaScript when a WordPress administrator views certain areas of their dashboard.

Autoptimize 2.7 with Critical CSS integrated, beta out

by

The title says it all; I just pushed the first beta of Autoptimize 2.7 which has some small fixes/ improvements but which most importantly finally sees the “Autoptimize CriticalCSS.com power-up” fully integrated.

Next to the actual integration and switching to object-oriented for most (but not all) of AOCCSS files, there are some minor functional changes as well, most visible ones being buttons to clear all rules and to clear all jobs from the queue.
I hope to be able to release AO27 officially in April, but for that I need the beta thoroughly tested off course. Most important part to test is the critical CSS logic obviously, so if you have the power-up running, download/ install the beta and simply disable the power-up to have Autoptimize fill that void (if the power-up is active, AO refrains from loading it’s own critical CSS functionality).
