CVE-2021-31590: Pwndoc Project Pwndoc

High severity, CVSS 8.8. EPSS: 2.7% chance of exploitation in the next 30 days.

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.

Affected products

• Pwndoc Project Pwndoc: before 0.4.0 (fixed in 0.4.0)
