CVE-2026-59891 CRITICAL PATCH Act Now

Credential leakage in sigstore-js (specifically the @sigstore/oci package) before 0.7.1 allows Docker registry credentials to be transmitted to the wrong registry because getRegistryCredentials() matched configured auth keys against the target registry using a substring check instead of an exact host match. An attacker who can induce a victim to push or pull signatures/attestations against an attacker-named registry whose hostname has a substring relationship with a legitimately configured registry (e.g. 'cr.io' vs 'ghcr.io', or 'victim.127.0.0.1:5000' vs '127.0.0.1:5000') can capture the victim's stored registry credentials. There is no public exploit identified at time of analysis, and this is not listed in CISA KEV; the underlying weakness (CWE-522) is confirmed and fixed by the vendor in @sigstore/oci 0.7.1.
