Nervos CKB calculation of program load cycles may be missed when executing in resume mode
Real-World Exposure
ckbReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.
Description
Impact
The calculation of program load cycles may be missed when executing in resume mode. Since the script execution order is now determined, this issue does not cause network splitting.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🦀crates.io | ckb | ≥ 0.100.0 | No fix |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ckb, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of ckb has shipped for GHSA-fjj4-2q73-jvgc yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-fjj4-2q73-jvgc can be triaged on real exposure rather than presence alone.
Tailored to GHSA-fjj4-2q73-jvgc. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
