frappe: Improper Neutralization of Special Elements Used in a Template Engine

Published Updated By the CyberSecBulletin desk

CVE-2025-68929 is a critical-severity improper neutralization of special elements used in a template engine vulnerability in frappe, with a CVSS 3.1 base score of 9.0 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. Affected frappe versions: < 14.99.6; >= 15.0.0, < 15.88.1. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.5% chance of exploitation within 30 days, which is low compared with other CVEs.

Critical severity: a successful attack would have severe impact.

What to do

  1. Check which version of frappe you run against the affected versions below, and install the vendor's latest release.
  2. Read the advisory on github.com for workarounds and exact fixed builds.
  3. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

Frappe is a full-stack web application framework. Prior to versions 14.99.6 and 15.88.1, an authenticated user with specific permissions could be tricked into accessing a specially crafted link. This could lead to a malicious template being executed on the server, resulting in remote code execution. Versions 14.99.6 and 15.88.1 fix the issue. No known workarounds are available.

The underlying weakness: Improper Neutralization of Special Elements Used in a Template Engine

The product uses a template engine to insert or process externally-influenced input, but it does not neutralize or incorrectly neutralizes special elements or syntax that can be interpreted as template expressions or other code directives when processed by the engine.

How developers prevent this class of flaw

  • Choose a template engine that offers a sandbox or restricted mode, or at least limits the power of any available expressions, function calls, or commands.
  • Use the template engine's sandbox or restricted mode, if available.
