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-2026-14587 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- neo4j (Bitnami): affected from 5.0.0; fixed in 5.26.29, 2026.7.0\n- neo4j-enterprise (Bitnami): affected from 5.0.0; fixed in 5.26.29, 2026.7.0\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-2026-14587/ (Markdown: https://insights.sbomify.com/CVE-2026-14587/index.md)","id":"CVE-2026-14587","markdown":"https://insights.sbomify.com/CVE-2026-14587/index.md","name":"CVE-2026-14587","record":{"aliases":["BIT-neo4j-2026-14587","BIT-neo4j-enterprise-2026-14587","GHSA-cwvv-9488-x4h5","MINI-2m62-8fpw-8j5p","MINI-2wpp-c69r-853x","MINI-48vw-8qw4-p8g8","MINI-4cgr-46x3-m39m","MINI-6mcf-mjg7-xw3v","MINI-6xx5-qhpx-22ch","MINI-9q4f-hgv3-r8jm","MINI-gprm-c992-3wfc","MINI-hjhf-cr88-7ffw","MINI-pmrm-c457-4chc","MINI-q2m5-253v-7c7f","MINI-q2vj-72wh-j4j7","MINI-q8fr-wqf9-g54c","MINI-xcv9-9fqq-xf3h"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Neo4j graph database","requires_auth":"none","summary":"Unauthenticated attackers can exhaust server resources by holding Bolt channels open via malformed handshake packets, causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Neo4j","cpe":[{"product":"neo4j","vendor":"neo4j"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-130","name":"Improper Handling of Length Parameter Inconsistency"}],"description":"Neo4j's Bolt modern handshake decoder treats an overlong capability bit mask the same way it treats a truncated bit mask. When an unauthenticated client sends a selected protocol version followed by 32 continuation bytes in the capability mask, the decoder resets the reader index and waits for more bytes instead of rejecting the protocol message and closing the channel.\n\nBecause the same unread bytes remain at the front of the decoder buffer, appending a terminating byte later does not recover the connection. The decoder re-reads the same first 32 continuation bytes, returns without producing a handshake-finalization message, and leaves the channel open.\n\nThis can be triggered before authentication by any client that can reach the Bolt connector.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Unathenticated connection can hold Bolt channel open","id":"CVE-2026-14587","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"WP Real IP-based Access Control \u003c= 1.3.1 - Unauthenticated Stored XSS via acl_ctrl_addr","id":"CVE-2026-14592"},"packages":[{"ecosystem":"Bitnami","fixed":["5.26.29","2026.7.0"],"introduced":["5.0.0","2025.1.0"],"last_affected":[],"package":"neo4j","purl":"pkg:bitnami/neo4j","source":"BIT-neo4j-2026-14587"},{"ecosystem":"Bitnami","fixed":["5.26.29","2026.7.0"],"introduced":["5.0.0","2025.1.0"],"last_affected":[],"package":"neo4j-enterprise","purl":"pkg:bitnami/neo4j-enterprise","source":"BIT-neo4j-enterprise-2026-14587"}],"prev":{"headline":"Assertion in libngtcp2 when under pressure in high concurrency DNS-over-QUIC environments","id":"CVE-2026-14586"},"products":["Community Edition","Enterprise Edition"],"published":"2026-08-05","related":[{"cvss_score":9.8,"headline":"Deserialization of Untrusted Data in Neo4j","id":"CVE-2021-34371","kev_date_added":null,"published":"2021-08-05"},{"cvss_score":9.8,"headline":"Incorrect access control in Neo4j Enterprise Database Server via LDAP authentication","id":"CVE-2018-18389","kev_date_added":null,"published":"2018-10-16"},{"cvss_score":6.8,"headline":"Neo4J vulnerable to Cross-Site Request Forgery","id":"CVE-2013-7259","kev_date_added":null,"published":"2014-04-29"},{"cvss_score":6.5,"headline":"Neo4j Cypher component mishandles IMMUTABLE privileges","id":"CVE-2024-34517","kev_date_added":null,"published":"2024-05-07"},{"cvss_score":2.1,"headline":"Caching of authentication context","id":"CVE-2026-1471","kev_date_added":null,"published":"2026-03-11"},{"cvss_score":2.1,"headline":"Auth misconfiguration when multiple providers enabled","id":"CVE-2026-1524","kev_date_added":null,"published":"2026-03-11"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"2026-08-05","vendors":["neo4j"]},"summary":"Unauthenticated attackers can exhaust server resources by holding Bolt channels open via malformed handshake packets, causing denial of service.","url":"https://insights.sbomify.com/CVE-2026-14587/"}
