It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4407 in the wild and no public exploit code.\n\nAffected product: Xpdf. 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-2026-4407/ (Markdown: https://insights.sbomify.com/CVE-2026-4407/index.md)","id":"CVE-2026-4407","markdown":"https://insights.sbomify.com/CVE-2026-4407/index.md","name":"CVE-2026-4407","record":{"aliases":["GHSA-7cj6-p2f2-f38h","UBUNTU-CVE-2026-4407"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PDF rendering library","requires_auth":"none","summary":"An out-of-bounds array write in Xpdf allows attackers to execute arbitrary code or cause denial of service via malicious PDF files.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GandC","cpe":[],"cvss":{"score":2.1,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Out-of-bounds array write in Xpdf 4.06 and earlier, due to incorrect validation of the \"N\" field in ICCBased color spaces.","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":"Out-of-bounds array write in Xpdf 4.06 due to missing validation","id":"CVE-2026-4407","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Samba: remote code execution in samr","id":"CVE-2026-4408"},"packages":[],"prev":{"headline":"Gravity Forms \u003c= 2.9.30 - Reflected Cross-Site Scripting via 'form_ids' Parameter","id":"CVE-2026-4406"},"products":["Xpdf"],"published":"2026-03-18","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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-19","vendors":["Xpdf"]},"summary":"An out-of-bounds array write in Xpdf allows attackers to execute arbitrary code or cause denial of service via malicious PDF files.","url":"https://insights.sbomify.com/CVE-2026-4407/"}
