CVE-2026-111036 Details
Description
Server-side request forgery (SSRF) vulnerability in the Coupa Supplier Portal SaaS platform, specifically in the document conversion functionality available in the ‘Contracts > Templates’ section. The vulnerability is due to insufficient validation of references to external resources processed by the Aspose.Words for Java library during DOCX-to-PDF conversion. An authenticated attacker with permissions to modify templates could upload a specially crafted DOCX document containing references to external resources, which would cause the server-side application to access URLs controlled by the attacker, resources on the internal network, or local files. A successful exploit could lead to the disclosure of sensitive information, such as configuration files, system files, credentials, environment variables and endpoints for internal services.
A server-side request forgery (SSRF) vulnerability has been identified in the Coupa Supplier Portal SaaS platform, specifically within the document conversion feature in the 'Contracts > Templates' section. This vulnerability arises from inadequate validation of external resource references handled by the Aspose.Words for Java library during the conversion of DOCX files to PDF. An authenticated attacker with the ability to modify templates could upload a specially crafted DOCX file that includes references to external resources. This would prompt the server-side application to access URLs controlled by the attacker, internal network resources, or local files. Exploiting this vulnerability could result in the unauthorized disclosure of sensitive information such as configuration files, system files, credentials, environment variables, and endpoints for internal services.
