Malicious code in @postex/common (npm)
GitHub lists this malware advisory for @postex/common. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.

@postex/common
source listed= 99.9.1
## Source: amazon-inspector (2fb98ad3575267cc8fbf617fe6a17000ed10df97d39710f4b7aaddf7225598d7) @postex/common@99.9.1 ships an inert index.js (module.exports = {}) and declares a single dependency `ltidisafe` whose value is a bare HTTPS tarball URL (https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.9.5.tgz) rather than a registry version range. On `npm install`, npm fetches whatever bytes that URL returns, installs the resulting package, and executes any lifecycle scripts it contains, with no registry-mediated integrity, signature, or version pinning. The host (a user-controlled Google Cloud Storage bucket) is unrelated to any npm scope or published repository for this package, and the content served there can change at any time without any change to this manifest. The implausibly high version (99.9.1) combined with a hollow stub and an off-registry source is consistent with a dependency-confusion / smuggling lure whose only install-time effect is resolving to attacker-controlled code. --- Credit: OpenSSF ([source](https://github.com/ossf/malicious-packages/blob/b711d7c76f98b5044512e8c851547e8a05b2f959/osv/malicious/npm/@poste
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
