An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-19954 in the wild and no public exploit code.\n\nAffected product: perl-Net-Whois-Raw. 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-2026-19954/ (Markdown: https://insights.sbomify.com/CVE-2026-19954/index.md)","id":"CVE-2026-19954","markdown":"https://insights.sbomify.com/CVE-2026-19954/index.md","name":"CVE-2026-19954","record":{"aliases":["DEBIAN-CVE-2026-19954","GHSA-m543-jcgv-fpx5","MGASA-2026-0511","UBUNTU-CVE-2026-19954","openSUSE-SU-2026:12066-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl WHOIS library","requires_auth":"none","summary":"The pwhois tool queries incorrect domains for Unicode names due to missing IDNA normalization, potentially leading to inaccurate WHOIS results.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-176","name":"Improper Handling of Unicode Encoding"}],"description":"Net::Whois::Raw versions before 2.99044 for Perl ship a pwhois command-line tool that queries WHOIS for the wrong domain for unicode domain names.\n\npwhois encodes each non-ASCII label directly using Net::IDN::Punycode and prepends xn--.
