GHSA-m4hc-m2v6-hfw8
HIGHImproper authorization on debug and artifact file downloads
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Blast Radius
sentryReal-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 authenticated user can download a debug or artifact bundle from arbitrary organizations and projects with a known bundle ID. The user does not need to be a member of the organization or have permissions on the project.
Patches
A patch was issued to ensure authorization checks are properly scoped on requests to retrieve debug or artifact bundles. Authenticated users who do not have the necessary permissions on the particular project are no longer able to download them.
Sentry SaaS users do not need to take any action. Self-Hosted Sentry users should upgrade to version 23.5.2 or higher.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for sentry. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update sentry to 23.5.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-m4hc-m2v6-hfw8 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-m4hc-m2v6-hfw8 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-m4hc-m2v6-hfw8. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-m4hc-m2v6-hfw8 in your dependencies?
O3 detects GHSA-m4hc-m2v6-hfw8 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
