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-2026-9334 in the wild and no public exploit code.\n\nAffected product: RURBAN Cpanel::JSON::XS. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-9334/ (Markdown: https://insights.sbomify.com/CVE-2026-9334/index.md)","id":"CVE-2026-9334","markdown":"https://insights.sbomify.com/CVE-2026-9334/index.md","name":"CVE-2026-9334","record":{"aliases":["AZL-89396","DEBIAN-CVE-2026-9334","GHSA-qfqj-xxqv-cxfw","UBUNTU-CVE-2026-9334"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Perl JSON library","requires_auth":"none","summary":"Attackers can cause crashes or potential code execution in Perl applications using Cpanel::JSON::XS with duplicate key handling enabled.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[{"product":"cpanel\\","vendor":"rurban"}],"cvss":{"score":7.3,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-843","name":"Access of Resource Using Incompatible Type"}],"description":"Cpanel::JSON::XS versions before 4.41 for Perl allow type confusion via duplicate object keys when dupkeys_as_arrayref is enabled.\n\ndecode_hv() collapses duplicate object keys into an array reference under dupkeys_as_arrayref.
