The Brief

CISA warned federal agencies that attackers have started exploiting a recently patched high-severity WordPress remote code execution flaw in the wild.
The flaw is a remote code execution (RCE) vulnerability in WordPress, which was already patched before exploitation was reported.

Attackers are actively exploiting this WordPress RCE flaw, so WordPress sites that have not applied the patch can be compromised.
