WORDPRESS CLICK2SHELL FLAW ENABLES RCE AFTER ONE ADMIN CLICK

Summary from the TLDR InfoSec newsletter

Click2Shell exploited an unsanitized theme slug passed into WordPress's admin panel jQuery selector, letting an attacker silently trigger theme installation using the logged-in administrator's own session token. When chained with a missing nonce/capability check in the Mobile Repair Zone 2.5.4 theme's AJAX handler, the flaw escalated to full RCE without the attacker needing any WordPress account. No CVE had been assigned at disclosure. Defenders should patch to WordPress 7.1.1 (or backports 7.0.5, 6.9.8, and 6.8.9) and set DISALLOW_FILE_MODS to block the installation stage entirely.
