If successfully exploited, this vulnerability could allow an attacker to:

: Added support for video file uploads and file uploads within the online editor's link settings. Multilingual Support

If you are running an environment that still utilizes legacy code from the Nicepage 4.16.0 ecosystem, immediate action is mandatory to ensure site integrity. nicepage 4.16.0 exploit

: Around mid-2022, security patches for Nicepage frequently adjusted file upload restrictions in contact forms and fixed how credentials were read within the property panel. Version 4.16.0 sits in a generation of code that attackers target using public proof-of-concept (PoC) scanners to identify unpatched installations. Key Technical Risks of the Exploit

While there is no record of a major publicized exploit specifically titled "Nicepage 4.16.0 exploit" as of April 2026, Nicepage version 4.16.0 was released on August 8, 2022, primarily focusing on new editor features such as element locking.

If input parameters are inadequately validated, malicious actors can feed unvetted payload queries into contact form elements. This allows attackers to discover target parameters or interact with raw submission objects, occasionally opening side-channel avenues to manipulate asset locations. The Operational Risks to Vulnerable Sites

Within days, the PoC was mirrored to Exploit-DB (EDB-ID: 58923) and GitHub under multiple repositories with names like nicepage-exploit and CVE-2026-1234 (a placeholder CVE that, as of this writing, has not been officially assigned). Version 4

Utilize tools like Hide My WP Ghost to protect against plugin-related vulnerabilities.

As discussed in security audits across plugin environments on the Nicepage Support Forum , older instances of Nicepage are prone to exposing critical back-end pathways (such as /wp-admin hooks or exact server file locations) directly inside public-facing theme source code. This footprint allows attackers to perform precise directory brute-forcing and target known underlying exploits in the hosting environment. Technical Breakdown of an RCE Exploitation Workflow
