CVE-2026-45321 (GCVE-0-2026-45321)

Vulnerability from nvd – Published: 2026-05-12 00:12 – Updated: 2026-05-28 03:55

Title

Malware in 42 @tanstack/* packages exfiltrates cloud credentials, GitHub tokens, and SSH keys

Summary

On 2026-05-11, between approximately 19:20 and 19:26 UTC, 84 malicious versions across 42 @tanstack/* packages were published to the npm registry. The publishes were authenticated via the legitimate GitHub Actions OIDC trusted-publisher binding for TanStack/router, but the publish workflow itself was not modified. The attacker chained three known vulnerability classes — a pull_request_target "Pwn Request" misconfiguration, GitHub Actions cache poisoning across the fork↔base trust boundary, and runtime memory extraction of the OIDC token from the Actions runner process — to publish credential-stealing malware under a trusted identity. Each affected package received exactly two malicious versions, published a few minutes apart.
