CVE-2026-8193 Details
Description
A weakness has been identified in Akaunting 3.1.21. This issue affects some unknown processing of the file config/dompdf.php of the component Invoice PDF Rendering. Executing a manipulation can lead to server-side request forgery. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
A server-side request forgery (SSRF) vulnerability has been identified in Akaunting version 3.1.21. The issue arises in the Invoice PDF Rendering component, specifically within the file config/dompdf.php. The vulnerability allows an authenticated user who can create or edit invoices to inject external resource tags into the notes section. When the PDF is generated, the server fetches these resources, potentially leading to unauthorized access of internal or attacker-controlled URLs.
It is recommended to disable remote fetching in Dompdf, restrict downloadable URL links to only http and https, and block loopback, private, link-local, and reserved IP ranges. Additionally, re-validate stored URLs at the time of download, use a dedicated HTTP client with redirect limits and timeouts, and if external URLs are not needed, remove URL-based downloadable links entirely.
