An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-40930 exists.\n\nAffected product: PJUHASZ JSON::SIMD. 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-2025-40930/ (Markdown: https://insights.sbomify.com/CVE-2025-40930/index.md)","id":"CVE-2025-40930","markdown":"https://insights.sbomify.com/CVE-2025-40930/index.md","name":"CVE-2025-40930","record":{"aliases":["GHSA-9pm2-v7x2-9mw5"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl JSON library","requires_auth":"none","summary":"An integer buffer overflow in the JSON::SIMD Perl library allows attackers to cause a denial of service via crafted JSON input.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[],"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-122","name":"Heap-based Buffer Overflow"}],"description":"JSON::SIMD before version 1.07 and earlier for Perl has an integer buffer overflow causing a segfault when parsing crafted JSON, enabling denial-of-service attacks or other unspecified impact.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Integer overflow in JSON::SIMD","id":"CVE-2025-40930","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"Apache::Session::Generate::MD5 versions through 1.94 for Perl create insecure session id","id":"CVE-2025-40931"},"packages":[],"prev":{"headline":"Integer overflow in Cpanel::JSON::XS","id":"CVE-2025-40929"},"products":["JSON::SIMD"],"published":"2025-09-08","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-04","vendors":["PJUHASZ"]},"summary":"An integer buffer overflow in the JSON::SIMD Perl library allows attackers to cause a denial of service via crafted JSON input.","url":"https://insights.sbomify.com/CVE-2025-40930/"}
