MEDIUMOpenstack DBaaS (Trove) Improper Link Resolution Before File Access
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.

troveReal-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
The _write_config function in trove/guestagent/datastore/experimental/mongodb/service.py, reset_configuration function in trove/guestagent/datastore/experimental/postgresql/service/config.py, write_config function in trove/guestagent/datastore/experimental/redis/service.py, _write_mycnf function in trove/guestagent/datastore/mysql/service.py, InnoBackupEx::_run_prepare function in trove/guestagent/strategies/restore/mysql_impl.py, InnoBackupEx::cmd function in trove/guestagent/strategies/backup/mysql_impl.py,MySQLDump::cmd in trove/guestagent/strategies/backup/mysql_impl.py, InnoBackupExIncremental::cmd function in trove/guestagent/strategies/backup/mysql_impl.py, _get_actual_db_status function in trove/guestagent/datastore/experimental/cassandra/system.py and trove/guestagent/datastore/experimental/cassandra/service.py, and multiple class CbBackup methods in trove/guestagent/strategies/backup/experimental/couchbase_impl.py in Openstack DBaaS (aka Trove) as packaged in Openstack before 2015.1.0 (aka Kilo) allows local users to write to configuration files via a symlink attack on a temporary file.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for trove. 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 trove to 4.0.0a0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-98c8-36p9-gw66 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-98c8-36p9-gw66 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-98c8-36p9-gw66. 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-98c8-36p9-gw66 in your dependencies?
O3 detects GHSA-98c8-36p9-gw66 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
