Which packages are affected by GHSA-j35p-q24r-5367?

GHSA-j35p-q24r-5367 affects the following packages: ckb (crates.io). Ecosystems affected: crates.io.

How do I fix GHSA-j35p-q24r-5367?

Update ckb to 0.43.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-j35p-q24r-5367 is resolved across your whole dependency graph.

How do I detect GHSA-j35p-q24r-5367 in my crates.io dependencies?

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.

How do I mitigate GHSA-j35p-q24r-5367 if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-j35p-q24r-5367?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-j35p-q24r-5367 can be triaged on real exposure rather than presence alone.

Is GHSA-j35p-q24r-5367 actively exploited in the wild?

No public exploit code has been indexed for GHSA-j35p-q24r-5367 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

Impact

A remote attacker could exploit this vulnerability to exhaust ckb process memory of an affected node.

Patches

Upgrade to 0.43.1 or later.

References

After resolving the outpoints of one dep group, we put the corresponding content into a vec ( https://github.com/nervosnetwork/ckb/blob/v0.42.0/util/types/src/core/cell.rs#L600-L617 ), there is a vulnerability to a memory dos attack because there is no determination of whether the outpoints is duplicated.
