The fix
We hold no Microsoft remediation data for CVE-2026-85732, which normally means it is not a Windows CVE. For non-Microsoft software the fix is the vendor's own updated release, and the affected versions are listed below.
What it is
oras-go is a Go library for managing OCI artifacts. Prior to 2.6.2, the parseLink function in registry/remote/utils.go accepts an absolute URL from a registry-controlled Link response header without validating its scheme, host, or port. Tags, Referrers, and Repositories pagination operations then issue a GET request to the attacker-selected URL from the victim's network, allowing blind server-side request forgery against internal services. The response body is not returned to the attacker, but timing and error differences can reveal service reachability, and credentials may be attached when the credential store has an entry for the target host. Exploitation requires a victim to perform a pagination-based listing operation against a malicious registry. The maintainer identifies this report as a duplicate of GHSA-3hr5-mjrr-hfjh and states that remediation is consolidated in that earlier advisory. The consolidated issue is fixed in version 2.6.2.
