Tactical Rmm: Improper Neutralization of Special Elements Used in a Template Engine
CVE-2025-69516 is a high-severity improper neutralization of special elements used in a template engine vulnerability in Tactical Rmm from AmidaWare, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 1.4.0 as the first without the flaw, so updating Tactical Rmm to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 2.28% chance of exploitation within 30 days, higher than 83% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Tactical Rmm to 1.4.0 or a later version.

Official description
A Server-Side Template Injection (SSTI) vulnerability in the /reporting/templates/preview/ endpoint of Amidaware Tactical RMM, affecting versions equal to or earlier than v1.3.1, allows low-privileged users with Report Viewer or Report Manager permissions to achieve remote command execution on the server. This occurs due to improper sanitization of the template_md parameter, enabling direct injection of Jinja2 templates. This occurs due to misuse of the generate_html() function, the user-controlled value is inserted into `env.from_string`, a function that processes Jinja2 templates arbitrarily, making an SSTI possible.

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.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
