An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-23526 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- helm.sh/helm/v3 (Go): affected all versions; fixed in 3.10.3\n- helm.sh/helm/v3 (Go): affected all versions; fixed in 3.10.3\n- helm.sh/helm/v3 (Go): affected all versions; fixed in 3.10.3\n- helm (Bitnami): affected from 3.0.0; fixed in 3.10.3\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2022-23526/ (Markdown: https://insights.sbomify.com/CVE-2022-23526/index.md)","id":"CVE-2022-23526","markdown":"https://insights.sbomify.com/CVE-2022-23526/index.md","name":"CVE-2022-23526","record":{"aliases":["AZL-11656","BIT-helm-2022-23526","CLEANSTART-2026-DR45541","GHSA-67fx-wx78-jx33","GO-2022-1166"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes package manager","requires_auth":"none","summary":"A null pointer dereference in Helm's chartutil package allows attackers to cause a denial of service via malicious schema files.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"helm","vendor":"helm"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"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_chartutil_ package that can cause a segmentation violation. The _chartutil_ package contains a parser that loads a JSON Schema validation file. For example, the Helm client when rendering a chart will validate its values with the schema file. The _chartutil_ package parses the schema file and loads it into structures Go can work with. Some schema files can cause array data structures to be created causing a memory violation. Applications that use the _chartutil_ package in the Helm SDK to parse a schema file can suffer a Denial of Service when that input causes a panic that cannot be recovered from. 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 schema files that are correctly formatted before passing them to the _chartutil_ functions.","ecosystems":["Bitnami","Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Helm contains Denial of service through schema file","id":"CVE-2022-23526","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"null_dereference","year":"2022"},"n_packages":4,"n_references":2,"next":{"headline":"Open Redirect in oidc_validate_redirect_url()","id":"CVE-2022-23527"},"packages":[{"ecosystem":"Bitnami","fixed":["3.10.3"],"introduced":["3.0.0"],"last_affected":[],"package":"helm","purl":"pkg:bitnami/helm","source":"BIT-helm-2022-23526"},{"ecosystem":"Go","fixed":["3.10.3"],"introduced":["0"],"last_affected":[],"package":"helm.sh/helm/v3","purl":null,"source":"GHSA-67fx-wx78-jx33"},{"ecosystem":"Go","fixed":["3.10.3"],"introduced":["0"],"last_affected":[],"package":"helm.sh/helm/v3","purl":"pkg:golang/helm.sh/helm/v3","source":"GHSA-67fx-wx78-jx33"},{"ecosystem":"Go","fixed":["3.10.3"],"introduced":["0"],"last_affected":[],"package":"helm.sh/helm/v3","purl":"pkg:golang/helm.sh/helm/v3","source":"GO-2022-1166"}],"prev":{"headline":"Helm vulnerable to Denial of service via NULL Pointer Dereference","id":"CVE-2022-23525"},"products":["helm"],"published":"2022-12-15","related":[{"cvss_score":9.8,"headline":"Helm Unsafe Link Following","id":"CVE-2019-18658","kev_date_added":null,"published":"2019-11-12"},{"cvss_score":9.8,"headline":"Helm Improper Certificate Validation","id":"CVE-2019-1010275","kev_date_added":null,"published":"2019-07-17"},{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2019-25210","kev_date_added":null,"published":"2024-03-03"},{"cvss_score":8.5,"headline":"Helm Chart Dependency Updating With Malicious Chart.yaml Content And Symlink Can Lead To Code Execution","id":"CVE-2025-53547","kev_date_added":null,"published":"2025-07-08"},{"cvss_score":8.5,"headline":"lookup Function Information Discolosure in Helm","id":"CVE-2020-11013","kev_date_added":null,"published":"2020-04-24"},{"cvss_score":8.4,"headline":"Helm has a path traversal in plugin metadata version enables arbitrary file write outside Helm plugin directory","id":"CVE-2026-35204","kev_date_added":null,"published":"2026-04-09"},{"cvss_score":8.4,"headline":"Helm's plugin verification fails open when .prov is missing, allowing unsigned plugin install","id":"CVE-2026-35205","kev_date_added":null,"published":"2026-04-09"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-18","vendors":["helm"]},"summary":"A null pointer dereference in Helm's chartutil package allows attackers to cause a denial of service via malicious schema files.","url":"https://insights.sbomify.com/CVE-2022-23526/"}
