{"id":"CVE-2021-31590","details":"PwnDoc all versions until 0.4.0 (2021-08-23) has incorrect JSON Webtoken handling, leading to incorrect access control. With a valid JSON Webtoken that is used for authentication and authorization, a user can keep his admin privileges even if he is downgraded to the \"user\" privilege. Even after a user's account is deleted, the user can still access the administration panel (and add or delete users) and has complete access to the system.","modified":"2026-03-15T21:59:21.104075Z","published":"2021-07-19T20:15:08.660Z","references":[{"type":"ADVISORY","url":"https://github.com/pwndoc/pwndoc/security/advisories"},{"type":"FIX","url":"https://github.com/pwndoc/pwndoc/blob/59519735b0d831d8fd96d7c3387f66d28407e583/CHANGELOG.md#040-2021-08-23"},{"type":"FIX","url":"https://github.com/pwndoc/pwndoc/commit/15f3dc0e212eda465e05fda0feb002d1bce2939d"},{"type":"FIX","url":"https://github.com/pwndoc/pwndoc/commit/ff1b868cec55f5b6c7a91e15a2b0b1f4324121ab"},{"type":"FIX","url":"https://github.com/pwndoc/pwndoc/pull/128"},{"type":"FIX","url":"https://github.com/pwndoc/pwndoc/pull/74"},{"type":"EVIDENCE","url":"https://www.dgc.org/responsible_disclosure_pwndoc_jwt"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pwndoc/pwndoc","events":[{"introduced":"0"},{"fixed":"59519735b0d831d8fd96d7c3387f66d28407e583"},{"fixed":"15f3dc0e212eda465e05fda0feb002d1bce2939d"},{"fixed":"ff1b868cec55f5b6c7a91e15a2b0b1f4324121ab"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"0.4.0"}]}}],"versions":["v0.1.0","v0.2.0","v0.3.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-31590.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
