MAL-2026-6563: Malicious code in @thone33/analytics-injector (npm)

0
Critical
Published: 06/29/2026 (06/29/2026, 04:50:56 UTC)
Source: GCVE Database
Product: @thone33/analytics-injector

Description

The npm package @thone33/analytics-injector versions 1.0.0 and 1.0.1 contains malicious code that executes attacker-controlled JavaScript. Its activate() function fetches a script from a mutable remote repository without integrity checks and evaluates it with full Node.js process privileges. This allows remote code execution controlled by an attacker. The package masquerades as an analytics helper but is designed for misdirection. No official patch or remediation is currently documented.

Technical Analysis

The @thone33/analytics-injector npm package (versions 1.0.0 and 1.0.1) exports an activate() function that fetches JavaScript code from a remote URL on a mutable GitHub repository branch and executes it via eval without verifying integrity. This results in arbitrary remote code execution with full Node.js process privileges for any consumer invoking activate(). The package's naming and remote repository suggest deliberate malicious intent rather than legitimate functionality. There is no indication of an official fix or patch available.

Potential Impact

Any application importing and invoking the activate() function of this package will execute attacker-controlled code with full privileges of the Node.js process. This can lead to complete compromise of the host environment, data theft, or further malicious actions. The remote code can change at any time without requiring a package update, making the threat persistent and dynamic.

Mitigation Recommendations

No official patch or remediation is currently documented for this package. The recommended mitigation is to avoid using @thone33/analytics-injector versions 1.0.0 and 1.0.1 entirely. Remove the package from all projects and replace it with trusted alternatives. Monitor dependencies for malicious packages and verify package provenance before use.
