How severe is CVE-2024-54134?

No CVSS score has been assigned to CVE-2024-54134 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2024-54134?

CVE-2024-54134 affects the following packages: @solana/web3.js (npm). Ecosystems affected: npm.

How do I fix CVE-2024-54134?

Update @solana/web3.js to 1.95.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-54134 is resolved across your whole dependency graph.

How do I detect CVE-2024-54134 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @solana/web3.js, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2024-54134 if there is no patch (or I can't update yet)?

Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.

Is CVE-2024-54134 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-54134 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.

What is the EPSS score for CVE-2024-54134?

CVE-2024-54134 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 46th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2024-54134?

CVE-2024-54134 is classified as Information Exposure (CWE-200). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2024-54134 published, and has it been updated?

CVE-2024-54134 was published on December 4, 2024 and was last updated on October 28, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Earlier today, a publish-access account was compromised for @solana/web3.js, a JavaScript library that is commonly used by Solana dapps. This allowed an attacker to publish unauthorized and malicious packages that were modified, allowing them to steal private key material and drain funds from dapps, like bots, that handle private keys directly. This issue should not affect non-custodial wallets, as they generally do not expose private keys during transactions. This is not an issue with the Solana protocol itself, but with a specific JavaScript client library and only appears to affect projects that directly handle private keys and that updated within the window of 3:20pm UTC and 8:25pm UTC on Tuesday, December 3, 2024.

These two unauthorized versions (1.95.6 and 1.95.7) were caught within hours and have since been unpublished.

We are asking all Solana app developers to upgrade to version 1.95.8. Developers pinned to latest should also upgrade to 1.95.8.

Developers that suspect they might be compromised should rotate any suspect authority keys, including multisigs, program authorities, server keypairs, and so on.
