What is CVE-2026-16547?

The REST API Log plugin for WordPress, prior to version 1.7.1, has security weaknesses where the token intended to protect the log download feature does not adequately bind to the requested log entry. Furthermore, it fails to verify the requester's permissions. This oversight permits unauthenticated individuals possessing the token to access and download logged REST API interactions, which may include sensitive information such as user credentials and private content.

Affected Version(s)

REST API Log 0 < 1.7.1

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
