Fix not verifiedA 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 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.
An attacker operating through a network path may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
