How severe is CVE-2022-23525?

CVE-2022-23525 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-2022-23525?

CVE-2022-23525 affects the following packages: helm.sh/helm/v3 (Go). Ecosystems affected: Go.

How do I fix CVE-2022-23525?

Update helm.sh/helm/v3 to 3.10.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-23525 is resolved across your whole dependency graph.

How do I detect CVE-2022-23525 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for helm.sh/helm/v3. 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.

How do I mitigate CVE-2022-23525 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 CVE-2022-23525?

O3 pinpoints whether CVE-2022-23525 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2022-23525 actively exploited in the wild?

No public exploit code has been indexed for CVE-2022-23525 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-2022-23525?

CVE-2022-23525 has an EPSS (Exploit Prediction Scoring System) score of 0.8%, placing it in the 52th 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-2022-23525?

CVE-2022-23525 is classified as NULL Pointer Dereference (CWE-476). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2022-23525 published, and has it been updated?

CVE-2022-23525 was published on December 15, 2022 and was last updated on April 10, 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

Helm is a tool for managing Charts, pre-configured Kubernetes resources. Versions prior to 3.10.3 are subject to NULL Pointer Dereference in the _repo_package. The repo package contains a handler that processes the index file of a repository. For example, the Helm client adds references to chart repositories where charts are managed. The repo package parses the index file of the repository and loads it into structures Go can work with. Some index files can cause array data structures to be created causing a memory violation. Applications that use the repo package in the Helm SDK to parse an index file can suffer a Denial of Service when that input causes a panic that cannot be recovered from. The Helm Client will panic with an index file that causes a memory violation panic. Helm is not a long running service so the panic will not affect future uses of the Helm client. This issue has been patched in 3.10.3. SDK users can validate index files that are correctly formatted before passing them to the repo functions.
