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-2026-47898 in the wild and no public exploit code.\n\nAffected product: Apache Lucene.Net. 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-2026-47898/ (Markdown: https://insights.sbomify.com/CVE-2026-47898/index.md)","id":"CVE-2026-47898","markdown":"https://insights.sbomify.com/CVE-2026-47898/index.md","name":"CVE-2026-47898","record":{"aliases":["GHSA-m739-f9cm-66x2"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Lucene.Net library","requires_auth":"high_privilege","summary":"An attacker can exploit an XML External Entity vulnerability in the Lucene.Net.Analysis.Common library to read sensitive data or cause denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"lucene.net","vendor":"apache"}],"cvss":{"score":4,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"Improper Restriction of XML External Entity Reference vulnerability in Apache Lucene.Net (Lucene.Net.Analysis.Common library).\n\nThis issue affects Apache Lucene.Net.Analysis.Common: from 4.8.0-beta00005 before 4.8.0-beta00018.\n\nUsers are recommended to upgrade to version 4.8.0-beta00018, which fixes the issue.","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":"Apache Lucene.Net: XXE vulnerability in Lucene.Net.Analysis.Common PatternParser","id":"CVE-2026-47898","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xxe","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Arbitrary File Read, Write, Rename, and Delete in Logseq","id":"CVE-2026-47899"},"packages":[],"prev":{"headline":"Apache Lucene.Net: Arbitrary file write from malicious server to Lucene.Net.Replicator client","id":"CVE-2026-47897"},"products":["Apache Lucene.Net"],"published":"2026-07-03","related":[{"cvss_score":8.9,"headline":"Apache Lucene.Net: Unauthenticated arbitrary file read on the Lucene.Net.Replicator replication server","id":"CVE-2026-47896","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":8.9,"headline":"Apache Lucene.Net: Arbitrary file write from malicious server to Lucene.Net.Replicator client","id":"CVE-2026-47897","kev_date_added":null,"published":"2026-07-03"},{"cvss_score":8,"headline":"Apache Lucene.Net.Replicator: Remote Code Execution in Lucene.Net.Replicator","id":"CVE-2024-43383","kev_date_added":null,"published":"2024-10-31"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-06","vendors":["Apache Software Foundation"]},"summary":"An attacker can exploit an XML External Entity vulnerability in the Lucene.Net.Analysis.Common library to read sensitive data or cause denial of service.","url":"https://insights.sbomify.com/CVE-2026-47898/"}
