Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

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.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for sentry, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update sentry to 23.7.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9jcq-jf57-c62c is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
