GHSA-67fj-6w6m-w5j8
HIGHReversible One-Way Hash in io.github.javaezlib:JavaEZ
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
io.github.javaezlib:JavaEZReal-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
Impact
This weakness allows the force decryption of locked text by hackers. The issue is NOT critical for non-secure applications, however may be critical in a situation where the highest levels of security are required. This issue ONLY affects v1.6 and does not affect anything pre-1.6. Upgrading to 1.7 is advised.
Patches
The vulnerability has been patched in release 1.7.
Workarounds
Currently there is no way to fix the issue without upgrading.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.github.javaezlib:JavaEZ. 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 io.github.javaezlib:JavaEZ to 1.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-67fj-6w6m-w5j8 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-67fj-6w6m-w5j8 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-67fj-6w6m-w5j8. 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-67fj-6w6m-w5j8 in your dependencies?
O3 detects GHSA-67fj-6w6m-w5j8 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
