Another update for WordPress announced (2.8.3) – summarised here by the maintainers
Unfortunately, I missed some places when fixing the privilege escalation issues for 2.8.1. Luckily, the entire WordPress community has our backs. Several folks in the community dug deeper and discovered areas that were overlooked. With their help, the remaining issues are fixed in 2.8.3. Since this is a security release, upgrading is highly recommended
As mentioned it is worth keeping up to date on the new revisions – the process pretty painless and straightforward so there is no excuse.
