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-2026-0943 in the wild and no public exploit code.\n\nAffected product: JV HarfBuzz::Shaper. 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-2026-0943/ (Markdown: https://insights.sbomify.com/CVE-2026-0943/index.md)","id":"CVE-2026-0943","markdown":"https://insights.sbomify.com/CVE-2026-0943/index.md","name":"CVE-2026-0943","record":{"aliases":["GHSA-hmr2-524c-vv28","UBUNTU-CVE-2026-0943"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl HarfBuzz library","requires_auth":"none","summary":"A null pointer dereference in the bundled HarfBuzz library allows attackers to cause a denial of service in Perl applications using HarfBuzz::Shaper.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[{"product":"harfbuzz\\","vendor":"jv"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"},{"id":"CWE-1395","name":"Dependency on Vulnerable Third-Party Component"}],"description":"HarfBuzz::Shaper versions before 0.032 for Perl contains a bundled library with a null pointer dereference vulnerability. \n\nVersions before 0.032 contain HarfBuzz 8.4.0 or earlier bundled as hb_src.tar.gz in the source tarball, which is affected by CVE-2026-22693.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Null dereference in HarfBuzz::Shaper","id":"CVE-2026-0943","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Group invite - Moderately critical - Access bypass - SA-CONTRIB-2026-001","id":"CVE-2026-0944"},"packages":[],"prev":{"headline":"Missing authorization in Rede Itaú for WooCommerce — Payment PIX, Credit Card and Debit","id":"CVE-2026-0942"},"products":["HarfBuzz::Shaper"],"published":"2026-01-19","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-01-20","vendors":["JV"]},"summary":"A null pointer dereference in the bundled HarfBuzz library allows attackers to cause a denial of service in Perl applications using HarfBuzz::Shaper.","url":"https://insights.sbomify.com/CVE-2026-0943/"}
