CWE-918Published: June 11, 2019· Updated: Jun 17, 2026

10.0

CVSS v3.1

Official Description

Lack of validation in the HTML parser in RealObjects PDFreactor before 10.1.10722 leads to SSRF, allowing attackers to access network or file resources on behalf of the server by supplying malicious HTML content.

Technical Analysis

CVE-2019-12153 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), with a CVSS base score of 10.0.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
