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.

Description
Impact
OpenTSDB is vulnerable to Remote Code Execution vulnerability by writing user-controlled input to Gnuplot configuration file and running Gnuplot with the generated configuration.
Patches
Patched in 07c4641471c6f5c2ab5aab615969e97211eb50d9 and further refined in https://github.com/OpenTSDB/opentsdb/commit/fa88d3e4b5369f9fb73da384fab0b23e246309ba
Workarounds
Disable Gunuplot via tsd.core.enable_ui = true and remove the shell files https://github.com/OpenTSDB/opentsdb/blob/master/src/mygnuplot.bat and https://github.com/OpenTSDB/opentsdb/blob/master/src/mygnuplot.sh.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for net.opentsdb:opentsdb. 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 net.opentsdb:opentsdb to 2.4.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-76f7-9v52-v2fw 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-76f7-9v52-v2fw 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-76f7-9v52-v2fw. 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-76f7-9v52-v2fw in your dependencies?
O3 detects GHSA-76f7-9v52-v2fw across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
