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.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2026-45321","url":"https://www.suse.com/security/cve/CVE-2026-45321"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1265198 for CVE-2026-45321","url":"https://bugzilla.suse.com/1265198"}],"title":"SUSE CVE CVE-2026-45321","tracking":{"current_release_date":"2026-05-29T01:20:22Z","generator":{"date":"2026-05-29T01:20:22Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2026-45321","initial_release_date":"2026-05-29T01:20:22Z","revision_history":[{"date":"2026-05-29T01:20:22Z","number":"2","summary":"references added,severity changed from  to critical"}],"status":"interim","version":"2"}}}
