What is CVE-2026-103693?

The Frontend Dashboard and ProfileGrid plugins for WordPress are susceptible to a PHP object injection vulnerability. This flaw enables unauthenticated users to store malicious serialized PHP objects in user metadata, which are later deserialized when the public profile is accessed. Consequently, this may allow attackers to execute arbitrary file writes and potentially gain remote code execution capabilities, compromising the security of the affected WordPress installations.

Affected Version(s)

Frontend Dashboard 0 < 3.0.5

ProfileGrid 0 < 6.0.0.5

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.
