CVE-2025-68702
CVE-2025-68702 is a Broken Cryptographic Algorithm vulnerability in net.gleske:jervis. O3 Security confirms whether CVE-2025-68702 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Jervis has a SHA-256 Hex String Padding Bug
Blast Radius
net.gleske:jervisReal-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
Jervis is a library for Job DSL plugin scripts and shared Jenkins pipeline libraries. Prior to 2.2, Jervis uses padLeft(32, '0') when it should use padLeft(64, '0') because SHA-256 produces 32 bytes which equates to 64 hex characters. This vulnerability is fixed in 2.2.

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 CVE-2025-68702 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 CVE-2025-68702 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 CVE-2025-68702. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
