GHSA-36h5-vrq6-pp34
HIGHJervis's Salt for PBKDF2 derived from password
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
Vulnerability
The salt is derived from sha256Sum(passphrase). Two encryption operations with the same password will have the same derived key.
Impact
Pre-computation attacks.
Severity is considered low for internal uses of this library and high for consumers of this library.
Patches
Jervis will generate a random salt for each password and store it alongside the ciphertext.
Upgrade to Jervis 2.2.
Workarounds
None

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for net.gleske:jervis. 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.gleske:jervis to 2.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-36h5-vrq6-pp34 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-36h5-vrq6-pp34 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-36h5-vrq6-pp34. 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-36h5-vrq6-pp34 in your dependencies?
O3 detects GHSA-36h5-vrq6-pp34 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
