WordPress 5.0.1 Security Release is Now Available for Download!

WordPress 5.0.1 security release is now available. This security release was issued by WordPress and is for all the previous versions since WordPress 3.7. WordPress suggests strongly that you have this update applied to your WordPress website without any delay and so do we.

WordPress version 5.0 and earlier are affected by below-mentioned 11 security issues. Updated versions of WordPress 4.9 and older releases are also available for those who have not updated to WordPress 5.0 yet.

  • Karim El Ouerghemmi discovered that authors could alter metadata to delete files that they weren’t authorized to.
  • Simon Scannell of RIPS Technologies discovered that authors could create posts of unauthorized post types with specially crafted input.
  • Sam Thomas discovered that contributors could craft metadata in a way that resulted in PHP object injection.
  • Tim Coen discovered that contributors could edit new comments from higher-privileged users, potentially leading to a cross-site scripting vulnerability.
  • Tim Coen also discovered that specially crafted URL inputs could lead to a cross-site scripting vulnerability in some circumstances. WordPress itself was not affected, but plugins could be in some situations.
  • Team Yoast discovered that the user activation screen could be indexed by search engines in some uncommon configurations, leading to exposure of email addresses, and in some rare cases, default generated passwords.
  • Tim Coen and Slavco discovered that authors on Apache-hosted sites could upload specifically crafted files that bypass MIME verification, leading to a cross-site scripting vulnerability.

All the plugin authors are highly encouraged to read the 5.0.1 developer notes for information on backwards-compatibility.

We, WordPressers, owe it to the reporters of these issues for practising responsible disclosure. The previous version of WordPress, WordPress 5.0 was released on December 6, 2018. Know more about it here.
