# Telerik Reporting: XML entities in SVG let attackers read server files

Link for people: https://infrastack.ai/live/CVE-2026-118975 (this .md is for agents)

Telerik Reporting resolves external XML entities inside SVG content supplied to a report, so an attacker can read local or UNC files and make server-side network requests from the rendering host. The attacker needs a low-privilege account that can supply SVG content to a report.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Telerik Reporting version in your project references; it must be `20.3.26.1110` or later to be outside the affected range.
- Find out whether any users can upload or supply SVG content to reports rendered by the server.

## Fix

- Telerik Reporting: move to `20.3.26.1110` or later.

## Timeline

- 2026-11-12T10:37:45+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-118975

## From the sources

In Progress® Telerik® Reporting prior to version 20.3.26.1110, improper restriction of XML external entity references in the SVG processing engine allows an authenticated attacker with low privileges who can supply SVG content to a report to read local or UNC files, or trigger server-side network requests, from the report rendering host. External XML entities in SVG content were resolved without applying the configured strict resource resolver and report path validation. Disclosed content is limited by the permissions of the rendering process and by what the rendered report output exposes.
