High CVSS 8.8

An HTML injection vulnerability in Amidaware Inc Tactical RMM v1.3.1 and earlier allows authenticated users to inject arbitrary HTML content during the creation of a new agent via the POST /api/v3/newagent/ endpoint. The agent_id parameter accepts up to 255 characters and is improperly sanitized using DOMPurify.sanitize() with the html: true option enabled, which fails to adequately filter HTML input. The injected HTML is rendered in the Tactical RMM management panel when an administrator attempts to remove or shut down the affected agent, potentially leading to client-side attacks such as UI manipulation or phishing. NOTE: the Supplier's position is that this has incorrect information.

Matched remediation archetype

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
