Vulert verdict on side-effects-package 0.0.1-security i

Updated on 23 Oct 2026

Malicious package: every vulnerability Vulert records for side-effects-package is a malicious-package vulnerability — a published version contained hostile code rather than a bug. Do not install it, and check whether it is already resolved in your dependencies. The registry now serves only the placeholder release 0.0.1-security, which is how a package removed for abuse usually looks.

Package health score 35/100
  • Security Malicious code published

Malicious code has been published under this package before, which caps this score.

What to do: Do not install this package. If it is already in your dependency tree, remove or replace it, and check what resolved it in the first place. Vulert keeps watching the name: if a maintained replacement appears, you will see it here. Monitor it with Vulert →

Questions

About side-effects-package

Is side-effects-package safe to use?

No. Vulert records a malicious-package vulnerability for side-effects-package: a published version contained hostile code rather than a bug, and the package looks like one that was withdrawn for abuse. Do not install it, and check whether it is already resolved in your dependencies.

What is side-effects-package's Vulert package health score?

Vulert scores side-effects-package 35/100, which reads as risky. The score weighs the vulnerability record (40), maintenance and release cadence (25), adoption from dependents and stars (20) and community signals such as the OpenSSF scorecard and forks (15). Malicious code has been published under this package before, which caps this score.

Is the latest version of side-effects-package affected?

No. 0.0.1-security, the version you would install today, has no vulnerabilities on record against it. Earlier releases do — the version table above lists each release with what affects it.

How many vulnerabilities does side-effects-package have?

1 vulnerability is recorded for side-effects-package in the npm ecosystem: 1 critical, 0 high, 0 medium and 0 low. The ledger on this page lists the same counts next to the date of the most recent disclosure.

How often are new side-effects-package vulnerabilities disclosed?

0 vulnerabilities were recorded for side-effects-package in the last 12 months, and the oldest entry in this database dates to 28 Jun 2025. Recency matters more than a lifetime total: it shows how actively new issues are being disclosed for the package you are considering.

Which versions of side-effects-package are affected?

Each vulnerability on this page lists the affected version range and the fixed version to move to. Open the vulnerability for the version you actually run — fixes are specific to a release line, not to the package as a whole.

What does a malicious-package vulnerability mean?

It means the published package itself contained hostile code — a backdoor, a credential stealer or similar — rather than only a bug. Registries remove such packages once they are confirmed, so treat any application that resolved an affected version as compromised and rotate the credentials it could reach.

How do I monitor side-effects-package for upcoming vulnerabilities?

Upload the manifest or SBOM for your application at vulert.com/scanner and Vulert keeps checking the side-effects-package version you actually run against new disclosures, then alerts you when one affects it. There is no installation and no source-code access required.
