GHSA-hcxx-mp6g-6gr9
HIGHOpencast publishes global system account credentials
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
org.opencastproject:opencast-commonReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
The issue was mostly mitigated before, drastically reducing the risk. See references below for more information.
Impact
Opencast before version 10.6 will try to authenticate against any external services listed in a media package when it is trying to access the files, sending the global system user's credentials, regardless of the target being part of the Opencast cluster or not.
Previous mitigations already prevented clear text authentications for such requests (e.g. HTTP Basic authentication), but with enough malicious intent, even hashed credentials can be broken.
Patches
Opencast 10.6 will now send authentication requests only against servers which are part of the Opencast cluster, preventing external services from getting any form of authentication attempt in the first place.
Workarounds
No workaround available.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.opencastproject:opencast-common. 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 org.opencastproject:opencast-common to 10.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hcxx-mp6g-6gr9 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-hcxx-mp6g-6gr9 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-hcxx-mp6g-6gr9. 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-hcxx-mp6g-6gr9 in your dependencies?
O3 detects GHSA-hcxx-mp6g-6gr9 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
