CVE-2024-42490 | authentik has Insufficient Authorization for several API endpoints

authentik is an open-source Identity Provider. Several API endpoints can be accessed by users without correct authentication/authorization. The main API endpoints affected by this are /api/v3/crypto/certificatekeypairs/<uuid>/view_certificate/, /api/v3/crypto/certificatekeypairs/<uuid>/view_private_key/, and /api/v3/.../used_by/. Note that all of the affected API endpoints require the knowledge of the ID of an object, which especially for certificates is not accessible to an unprivileged user. Additionally the IDs for most objects are UUIDv4, meaning they are not easily guessable/enumerable. authentik 2024.4.4, 2024.6.4 and 2024.8.0 fix this issue.

7.5 3.1 HIGH
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:L/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:N)
Service keeps running; no real outage angle.
