{"apiVersion":"1.0","identifier":"CVE-2026-41164","description":"nuts-node is the reference implementation of the Nuts specification. Prior to 6.2.3 and 5.4.31, the v1 access token introspection endpoint (/auth/v1/introspect_access_token) accepts any JWT signed by a key present on the node, without validating the JWT type, issuer-to-key binding, or required claims. This allows a Verifiable Presentation (VP) JWT to be replayed as an access token and receive an active: true introspection response. This vulnerability is fixed in 6.2.3 and 5.4.31.","publishedAt":"2026-05-26T18:16:47","lastModifiedAt":"2026-07-24T11:10:00","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-41164","cvssScore":4.4,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:L/A:N","epssProbability":0.00076,"riskScore":0.44,"affectedProduct":"nuts-node","affectedVersions":"<6.2.3, <5.4.31","vulnerabilityType":"Package","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-41164","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-41164","en":"https://www.redsauce.net/en/cves/CVE-2026-41164","fr":"https://www.redsauce.net/fr/cves/CVE-2026-41164","pt":"https://www.redsauce.net/pt/cves/CVE-2026-41164","de":"https://www.redsauce.net/de/cves/CVE-2026-41164","sk":"https://www.redsauce.net/sk/cves/CVE-2026-41164","el":"https://www.redsauce.net/el/cves/CVE-2026-41164"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-41164"}}
