CVE-2026-44016: CWE-94: Improper Control of Generation of Code ('Code Injection') in docling-project docling
Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. FIn versions >= 2.82.0, < 2.91.0, if the HTML backend was explicitly configured for rendering (rendering option by default deactivated), then the Playwright-based rendering feature could allow JavaScript execution and unrestricted network access when processing untrusted HTML documents. An attacker could craft malicious HTML that executes arbitrary JavaScript in the rendering context or makes unauthorized network requests to internal services, potentially leading to SSRF attacks, data exfiltration, or remote code execution in the rendering environment. This vulnerability is fixed in 2.91.0.
AI Analysis
Technical Summary
CVE-2026-44016 is a code injection vulnerability (CWE-94) in the docling-project's docling software affecting versions >=2.82.0 and <2.91.0 when the HTML backend rendering feature is explicitly enabled. The Playwright-based rendering allows malicious HTML to execute arbitrary JavaScript and perform unrestricted network requests, which can lead to server-side request forgery (SSRF), data exfiltration, or remote code execution in the rendering context. The vulnerability has a CVSS 3.1 score of 8.2, indicating high severity, and is resolved in version 2.91.0.
Potential Impact
An attacker who can supply untrusted HTML to the vulnerable docling versions with the HTML backend rendering enabled can execute arbitrary JavaScript code and make unauthorized network requests. This can result in SSRF attacks, unauthorized data access or exfiltration, and potentially remote code execution within the rendering environment, compromising confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade docling to version 2.91.0 or later where this vulnerability is fixed. Until then, avoid enabling the HTML backend rendering feature or only process trusted HTML documents. Patch status is confirmed fixed in 2.91.0.
