WordPress Click2Shell Forces Theme Install, Chains to RCE
WordPress has addressed a severe vulnerability known as Click2Shell, which enables attackers to force theme installations through specially crafted links without requiring any interaction from logged-in administrators. Discovered by security researchers, this flaw can lead to remote code execution on affected servers. The malicious attack exploits a discrepancy in how WordPress Core and browsers interpret URL links, allowing automatic activation of a theme’s PHP code during preview page builds. Security patches were released on September 17, for users running versions 6.0 and later, with prompts to update for administrators across various affected installations.
