In OAuthLib versions 3.1.1 until 3.2.1, an attacker providing malicious redirect uri can cause denial of service. An attacker can also leverage usage of `uri_validate` functions depending where it is used. OAuthLib applications using OAuth2.0 provider support or use directly `uri_validate` are affected by this issue. Version 3.2.1 contains a patch. There are no known workarounds." } ] }, "impact": { "cvss": { "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 5.7, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "REQUIRED", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H", "version": "3.1" } }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-20: Improper Input Validation" } ] } ] }, "references": { "reference_data": [ { "name": "https://github.com/oauthlib/oauthlib/security/advisories/GHSA-3pgj-pg6c-r5p7", "refsource": "CONFIRM", "url": "https://github.com/oauthlib/oauthlib/security/advisories/GHSA-3pgj-pg6c-r5p7" }, { "name": "https://github.com/oauthlib/oauthlib/commit/2e40b412c844ecc4673c3fa3f72181f228bdbacd", "refsource": "MISC", "url": "https://github.com/oauthlib/oauthlib/commit/2e40b412c844ecc4673c3fa3f72181f228bdbacd" }, { "name": "https://github.com/oauthlib/oauthlib/blob/2b8a44855a51ad5a5b0c348a08c2564a2e197ea2/oauthlib/uri_validate.py", "refsource": "MISC", "url": "https://github.com/oauthlib/oauthlib/blob/2b8a44855a51ad5a5b0c348a08c2564a2e197ea2/oauthlib/uri_validate.py" }, { "name": "https://github.com/oauthlib/oauthlib/blob/d4bafd9f1d0eba3766e933b1ac598cbbf37b8914/oauthlib/oauth2/rfc6749/grant_types/base.py#L232", "refsource": "MISC", "url": "https://github.com/oauthlib/oauthlib/blob/d4bafd9f1d0eba3766e933b1ac598cbbf37b8914/oauthlib/oauth2/rfc6749/grant_types/base.py#L232" }, { "name": "https://github.com/oauthlib/oauthlib/releases/tag/v3.2.1", "refsource": "MISC", "url": "https://github.com/oauthlib/oauthlib/releases/tag/v3.2.1" }, { "refsource": "FEDORA", "name": "FEDORA-2022-5a74a5eea7", "url": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/QRYLYHE5HWF6R2CRLJFUK4PILR47WXOE/" } ] }, "source": { "advisory": "GHSA-3pgj-pg6c-r5p7", "discovery": "UNKNOWN" } }
