Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to @tanstack/solid-router-devtools@1.166.19. The same advisory and Firewall decision cover these 2 recorded versions: 1.166.16, 1.166.19. - Avoid installing @tanstack/solid-router-devtools@1.166.19. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% This version falls within the @tanstack/\* package family compromised on 2026-05-11. The campaign published 42 packages × 2 versions each with the following structural fingerprints: a ~2.3 MB obfuscated JavaScript payload at the tarball root not declared in package.json's files array; an optionalDependencies entry pointing at an orphan commit in the repository's fork network (github:\/\\#\ form); a second-stage payload fetched from litter.catbox.moe (anonymous 72-hour-TTL file host); credential harvesting from AWS IMDS, GCP metadata, Kubernetes service account tokens, ~/.npmrc, GitHub tokens (env, gh CLI,.git-credentials), and SSH keys; exfiltration via Session/Oxen (filev2.getsession.org, seed{1,2,3}.getsession.org) to defeat IP/domain blocking; self-propagation by enumerating the victim maintainer's other packages via registry.npmjs.org/-/v1/search?text=maintainer:\ and republishing them; and scraping the GitHub Actions runner's OIDC token from /proc/\/mem to publish directly to registry.npmjs.org. Installing this version exposes any installer credentials reachable from the build/CI environment to attacker-controlled exfiltration channels. \#\# Source: ghsa-malware (3a732a8d98acc7dde8cda3fe949f1d2357f35b196af9ba42b70adfe005d3c5f1) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it. \#\# Source: google-open-source-security (5e1924464368f0c5816ee84e000cc47017f44045140feafbbc9e685d847ed5a5) This package was compromised as part of the "Mini Shai-Hulud is back" worm by the TeamPCP threat actor. The package will steal credentials and then propogate it to every package it has access to. The package also attempts to remain persistent. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** @tanstack/solid-router-devtools - **Ecosystem:** npm - **Version:** 1.166.19 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-09-13T13:20:10.181Z - **Known versions:** 4 - **Latest version:** 1.167.2 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [ADVISORY]() - [ARTICLE]() - [ARTICLE]() - [ARTICLE]() - [ARTICLE]() - [ARTICLE]()
