From 13.0.0 to before 13.7.1, there is an Authentication Bypass for client_credentials tokens. the league/oauth2-server library sets the JWT sub claim to the client identifier (since there's no user). The token guard then passes this value to retrieveById() without validating it's actually a user identifier, potentially resolving an unrelated real user. Any machine-to-machine token can inadvertently authenticate as an actual user. This vulnerability is fixed in 13.7.1."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:N","baseScore":7.1,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":1.8,"impactScore":4.7}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Primary","description":[{"lang":"en","value":"CWE-287"}]}],"references":[{"url":"https://github.com/laravel/passport/issues/1900","source":"security-advisories@github.com"},{"url":"https://github.com/laravel/passport/pull/1901","source":"security-advisories@github.com"},{"url":"https://github.com/laravel/passport/pull/1902","source":"security-advisories@github.com"},{"url":"https://github.com/laravel/passport/security/advisories/GHSA-349c-2h2f-mxf6","source":"security-advisories@github.com"},{"url":"https://github.com/thephpleague/oauth2-server/issues/1456#issuecomment-2734989996","source":"security-advisories@github.com"}]}}]}
