# CVE-2024-42490: GoAuthentik vulnerable to Insufficient Authorization for several API endpoints

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.5% , percentile 40: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 40% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes goauthentik.io (Go) >= 2024.6.0-rc1, < 2024.6.4, fixed in 2024.6.4 ; goauthentik.io (Go) < 2024.4.4, fixed in 2024.4.4 . Check your lockfile, including transitive dependencies.

## What it is

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/ /viewcertificate/, /api/v3/crypto/certificatekeypairs/ /viewprivatekey/, and /api/v3/.../usedby/. 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.

## Affected packages

- Go `goauthentik.io` >= 2024.6.0-rc1, < 2024.6.4 → fixed: 2024.6.4
- Go `goauthentik.io` < 2024.4.4 → fixed: 2024.4.4

## Affected products (CVE record)

- goauthentik authentik: < 2024.4.4, >= 2024.6.0-rc1, < 2024.6.4

## Severity

- GitHub_M CVSS 3.1: 7.5 `CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:L/A:N`
- GitHub CVSS 4.0: 9.1 `CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:H/SC:H/SI:N/SA:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact partial .
- FIRST EPSS (model of 2026-10-21): 0.48% probability of exploitation activity in the next 30 days; percentile 40.
