Where it stands

The Hacker News was first to report a new pre-authentication cross-site scripting (XSS) vulnerability in WordPress. This flaw could potentially lead to PHP code execution on affected servers. The vulnerability was addressed in WordPress 7.0.3, released on August 7. The release notes from WordPress.org blog confirm the patch, but do not specify the severity of the flaw.

Security Affairs and Search Engine Journal both describe the flaw as a high-severity XSS vulnerability. Security Affairs goes further, claiming that the flaw, dubbed XSS2Shell, could allow for full server takeover. This contradicts the more measured statements from WordPress.org blog and The Hacker News. Tech My Money describes how OpenAI Codex was used to mitigate the effects of the vulnerability, but does not specify how the tool was applied.

The current state of the vulnerability is unclear. WordPress has released a patch, but the extent of the threat and the effectiveness of the patch are still topics of debate. Security experts and WordPress users are advised to update to the latest version immediately. However, the potential for full server takeover, as suggested by Security Affairs, raises concerns about the adequacy of the patch.
