CVE-2025-53884 has a CVSS score of 5.3/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2025-53884?

CVE-2025-53884 affects the following packages: github.com/neuvector/neuvector (Go). Ecosystems affected: Go.

How do I fix CVE-2025-53884?

Update github.com/neuvector/neuvector to 0.0.0-20250825191744-da1a462074c3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-53884 is resolved across your whole dependency graph.

How do I detect CVE-2025-53884 in my Go dependencies?

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

How do I mitigate CVE-2025-53884 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.

Is CVE-2025-53884 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-53884 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-2025-53884?

CVE-2025-53884 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 7th 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-2025-53884?

CVE-2025-53884 is classified as CWE-759 (CWE-759). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.

Description

Impact

NeuVector stores user passwords and API keys using a simple, unsalted hash. This method is vulnerable to rainbow table attack (offline attack where hashes of known passwords are precomputed).

NeuVector generates a cryptographically secure, random 16-character salt and uses it with the PBKDF2 algorithm to create the hash value for the following actions:

Creating a user
Updating a user’s password
Creating an API key

Note: After upgrading to NeuVector 5.4.6, users must log in again so that NeuVector can regenerate the password hash. For API keys, you must send at least one request per API key to regenerate its hash value.

Patches

This issue is fixed in NeuVector version 5.4.6 and later.

Workarounds

There is no workaround. Upgrade to a patched version of NeuVector as soon as possible.
