When you make a request to an endpoint that requires the scope `foo` using an access token granted with that `foo` scope, introspection will be valid and that token will be cached. The problem comes when a second requests to an endpoint that requires the scope `bar` is made before the cache has expired. Whether the token is granted or not to the `bar` scope, introspection will be valid. A patch will be released with `v0.38.12-beta.1`. Per default, caching is disabled for the `oauth2_introspection` authenticator. When caching is disabled, this vulnerability does not exist. The cache is checked in [`func (a *AuthenticatorOAuth2Introspection) Authenticate(...)`](https://github.com/ory/oathkeeper/blob/6a31df1c3779425e05db1c2a381166b087cb29a4/pipeline/authn/authenticator_oauth2_introspection.go#L152). From [`tokenFromCache()`](https://github.com/ory/oathkeeper/blob/6a31df1c3779425e05db1c2a381166b087cb29a4/pipeline/authn/authenticator_oauth2_introspection.go#L97) it seems that it only validates the token expiration date, but ignores whether the token has or not the proper scopes. The vulnerability was introduced in PR #424. During review, we failed to require appropriate test coverage by the submitter which is the primary reason that the vulnerability passed the review process." } ] + }, + "impact": { + "cvss": { + "attackComplexity": "LOW", + "attackVector": "NETWORK", + "availabilityImpact": "NONE", + "baseScore": 7.5, + "baseSeverity": "HIGH", + "confidentialityImpact": "HIGH", + "integrityImpact": "NONE", + "privilegesRequired": "NONE", + "scope": "UNCHANGED", + "userInteraction": "NONE", + "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N", + "version": "3.1" + } + }, + "problemtype": { + "problemtype_data": [ + { + "description": [ + { + "lang": "eng", + "value": "CWE-863: Incorrect Authorization" + } + ] + } + ] + }, + "references": { + "reference_data": [ + { + "name": "https://github.com/ory/oathkeeper/security/advisories/GHSA-qvp4-rpmr-xwrr", + "refsource": "CONFIRM", + "url": "https://github.com/ory/oathkeeper/security/advisories/GHSA-qvp4-rpmr-xwrr" + }, + { + "name": "https://github.com/ory/oathkeeper/pull/424", + "refsource": "MISC", + "url": "https://github.com/ory/oathkeeper/pull/424" + }, + { + "name": "https://github.com/ory/oathkeeper/commit/1f9f625c1a49e134ae2299ee95b8cf158feec932", + "refsource": "MISC", + "url": "https://github.com/ory/oathkeeper/commit/1f9f625c1a49e134ae2299ee95b8cf158feec932" + } + ] + }, + "source": { + "advisory": "GHSA-qvp4-rpmr-xwrr", + "discovery": "UNKNOWN" } } \ No newline at end of file
