Privilege escalation via ApiTokensEndpoint

CVE-2023-39349 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

Impact

An attacker with access to a token with few or no scopes can query /api/0/api-tokens/ for a list of all tokens created by a user, including tokens with greater scopes, and use those tokens in other requests.

There is no evidence that the issue was exploited on https://sentry.io. For self-hosted users, it is advised to rotate user auth tokens via https://your-self-hosted-sentry-installation/settings/account/api/auth-tokens/.

Patches

The issue was fixed in https://github.com/getsentry/sentry/pull/53850 and is available in the release 23.7.2 of sentry and self-hosted.

Workarounds

There are no known workarounds.

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/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:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
Service keeps running; no real outage angle.
