Also, the changelog doesn’t describe anything, just a new version update.
If anything, it should say that it fixed a vulnerability that allowed a non-authenticated user to create new redirects. Or similar.
I don’t feel like that is violating the specifics of the vulnerability, just acknowledging that there was a bug, and that’s why you should update now.
Just to confirm, I’m seeing the same “Other: logged out” record in my Simple History logs. I also have iThemes Security installed.
We’re receiving this same error message, and a similar debug message in the dashboard, relevant to our hosting environment.
Latest version of WP (4.2.2) and Plugin (1.9.4)
