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.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-45321","reference_id":"","reference_type":"","scores":[{"value":"0.17051","scoring_system":"epss","scoring_elements":"0.95136","published_at":"2026-06-11T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-45321"},{"reference_url":"https://github.com/TanStack/router","reference_id":"","reference_type":"","scores":[{"value":"9.6","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/TanStack/router"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45321","reference_id":"","reference_type":"","scores":[{"value":"9.6","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45321"},{"reference_url":"https://socket.dev/blog/tanstack-npm-packages-compromised-mini-shai-hulud-supply-chain-attack","reference_id":"","reference_type":"","scores":[{"value":"9.6","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://socket.dev/blog/tanstack-npm-packages-compromised-mini-shai-hulud-supply-chain-attack"},{"reference_url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2026-45321","reference_id":"","reference_type":"","scores":[{"value":"9.6","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2026-45321"},{"reference_url":"https://github.com/TanStack/router/issues/7383","reference_id":"7383","reference_type":"","scores":[{"value":"9.6","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""},{"value":"Attend","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:A/A:N/T:T/P:M/B:A/M:M/D:A/2026-05-27T17:49:15Z/"}],"url":"https://github.com/TanStack/router/issues/7383"},{"reference_url":"https://github.com/TanStack/router/security/advisories/GHSA-g7cv-rxg3-hmpx","reference_id":"GHSA-g7cv-rxg3-hmpx","reference_type":"","scores":[{"value":"9.6","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""},{"value":"Attend","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:A/A:N/T:T/P:M/B:A/M:M/D:A/2026-05-27T17:49:15Z/"}],"url":"https://github.com/TanStack/router/security/advisories/GHSA-g7cv-rxg3-hmpx"},{"reference_url":"https://www.stepsecurity.io/blog/mini-shai-hulud-is-back-a-self-spreading-supply-chain-attack-hits-the-npm-ecosystem","reference_id":"mini-shai-hulud-is-back-a-self-spreading-supply-chain-attack-hits-the-npm-ecosystem","reference_type":"","scores":[{"value":"9.6","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""},{"value":"Attend","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:A/A:N/T:T/P:M/B:A/M:M/D:A/2026-05-27T17:49:15Z/"}],"url":"https://www.stepsecurity.io/blog/mini-shai-hulud-is-back-a-self-spreading-supply-chain-attack-hits-the-npm-ecosystem"},{"reference_url":"https://tanstack.com/blog/npm-supply-chain-compromise-postmortem","reference_id":"npm-supply-chain-compromise-postmortem","reference_type":"","scores":[{"value":"9.6","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},{"value":"CRITICAL","scoring_system":"generic_textual","scoring_elements":""},{"value":"Attend","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:A/A:N/T:T/P:M/B:A/M:M/D:A/2026-05-27T17:49:15Z/"}],"url":"https://tanstack.com/blog/npm-supply-chain-compromise-postmortem"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/375565?format=json","purl":"pkg:npm/%40tanstack/router-cli@1.166.50","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540tanstack/router-cli@1.166.50"}],"aliases":["CVE-2026-45321","GHSA-g7cv-rxg3-hmpx"],"risk_score":null,"exploitability":null,"weighted_severity":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-vewf-x8sv-d7an"}],"fixing_vulnerabilities":[],"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/packages/pkg:npm/%2540tanstack/router-cli@1.166.49"}
