CVE-2026-44016
Description
A flaw was found in Docling. If the HTML backend is explicitly configured for rendering, a remote attacker could exploit a vulnerability in the Playwright-based rendering feature by crafting malicious HTML documents. This could allow the attacker to execute arbitrary JavaScript or make unauthorized network requests, potentially leading to Server-Side Request Forgery (SSRF) attacks, data exfiltration, or remote code execution.
Statement
This vulnerability is rated as Important. While Docling's HTML backend rendering feature is deactivated by default in Red Hat OpenShift AI, an explicitly configured instance processing untrusted HTML documents could allow a remote attacker to execute arbitrary JavaScript or make unauthorized network requests. This could lead to Server-Side Request Forgery (SSRF), data exfiltration, or remote code execution within the rendering environment. However, Red Hat OpenShift AI (RHOAI) is not affected as the vulnerable code is not present.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
Integrity
Technical Impact: Execute Unauthorized Code or Commands
Access Control
Technical Impact: Bypass Protection Mechanism
By providing URLs to unexpected hosts or ports, attackers can make it appear that the server is sending the request, possibly bypassing access controls such as firewalls that prevent the attackers from accessing the URLs directly. The server can be used as a proxy to conduct port scanning of hosts in internal networks, use other URLs such as that can access documents on the system (using file://), or use other protocols such as gopher:// or tftp://, which may provide greater control over the contents of requests.
