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-2026-47896 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-2026-47896/ (Markdown: https://insights.sbomify.com/CVE-2026-47896/index.md)","id":"CVE-2026-47896","markdown":"https://insights.sbomify.com/CVE-2026-47896/index.md","name":"CVE-2026-47896","record":{"aliases":["GHSA-mggp-f2j5-mm3g"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Lucene.Net Replicator","requires_auth":"none","summary":"An unauthenticated attacker can read arbitrary files from the server via path traversal in the Lucene.Net.Replicator library.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"lucene.net","vendor":"apache"}],"cvss":{"score":8.9,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N/AU:Y/RE:L","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Apache Lucene.Net (Lucene.Net.Replicator library).\n\nThis issue affects Apache Lucene.Net.Replicator: from 4.8.0-beta00005 through 4.8.0-beta00017.\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: Unauthenticated arbitrary file read on the Lucene.Net.Replicator replication server","id":"CVE-2026-47896","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Lucene.Net: Arbitrary file write from malicious server to Lucene.Net.Replicator client","id":"CVE-2026-47897"},"packages":[],"prev":{"headline":"Use after free in strongSwan","id":"CVE-2026-47895"},"products":["Apache Lucene.Net"],"published":"2026-07-03","related":[{"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"},{"cvss_score":4,"headline":"Apache Lucene.Net: XXE vulnerability in Lucene.Net.Analysis.Common PatternParser","id":"CVE-2026-47898","kev_date_added":null,"published":"2026-07-03"}],"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 unauthenticated attacker can read arbitrary files from the server via path traversal in the Lucene.Net.Replicator library.","url":"https://insights.sbomify.com/CVE-2026-47896/"}
