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-2026-41720 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.springframework.ldap:spring-ldap-core (Maven): affected all versions up to 2.4.4; no fix listed\n- org.springframework.ldap:spring-ldap-core (Maven): affected all versions up to 2.4.4; no fix listed\n- org.springframework.ldap:spring-ldap-core (Maven): affected from 3.2.0 up to 3.2.16; no fix listed\n- org.springframework.ldap:spring-ldap-core (Maven): affected from 3.2.0 up to 3.2.16; no fix listed\n- org.springframework.ldap:spring-ldap-core (Maven): affected from 3.3.0; fixed in 3.3.8\n- org.springframework.ldap:spring-ldap-core (Maven): affected from 3.3.0; fixed in 3.3.8\n- org.springframework.ldap:spring-ldap-core (Maven): affected from 4.0.0; fixed in 4.0.4\n- org.springframework.ldap:spring-ldap-core (Maven): affected from 4.0.0; fixed in 4.0.4\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-2026-41720/ (Markdown: https://insights.sbomify.com/CVE-2026-41720/index.md)","id":"CVE-2026-41720","markdown":"https://insights.sbomify.com/CVE-2026-41720/index.md","name":"CVE-2026-41720","record":{"aliases":["CLEANSTART-2026-EX93158","CLEANSTART-2026-GT33551","CLSA-2026-1782176232","CLSA-2026-1788782659","CLSA-2026-1789146534","CLSA-2026-1789400252","CLSA-2026-1789415252","CLSA-2026-1789959015","CLSA-2026-1791968034","CLSA-2026-1791993126","CLSA-2026-1792072269","CLSA-2026-1792141850","CLSA-2026-1792591698","ECHO-4c80-bd8e-063b","GHSA-jrv5-8w28-4265","ROOT-APP-MAVEN-CVE-2026-41720"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Spring LDAP library","requires_auth":"none","summary":"Attackers can bypass authentication in Spring LDAP by providing a valid username with an empty or null password, gaining unauthorized access.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Spring LDAP's DirContextAuthenticationStrategy implementations do not reject a bind request where a non-empty username is paired with an empty or null password.\n\nAffected versions:\nSpring LDAP 2.4.0 through 2.4.4; 3.2.0 through 3.2.17; 3.3.0 through 3.3.7; 4.0.0 through 4.0.3.","ecosystems":["Maven"],"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":"Authentication Bypass with Empty Password in Spring LDAP","id":"CVE-2026-41720","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":8,"n_references":1,"next":{"headline":"Spring Data Commons Denial of Service via Data Binding","id":"CVE-2026-41721"},"packages":[{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["2.4.4"],"package":"org.springframework.ldap:spring-ldap-core","purl":null,"source":"GHSA-jrv5-8w28-4265"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["2.4.4"],"package":"org.springframework.ldap:spring-ldap-core","purl":"pkg:maven/org.springframework.ldap/spring-ldap-core","source":"GHSA-jrv5-8w28-4265"},{"ecosystem":"Maven","fixed":[],"introduced":["3.2.0"],"last_affected":["3.2.16"],"package":"org.springframework.ldap:spring-ldap-core","purl":null,"source":"GHSA-jrv5-8w28-4265"},{"ecosystem":"Maven","fixed":[],"introduced":["3.2.0"],"last_affected":["3.2.16"],"package":"org.springframework.ldap:spring-ldap-core","purl":"pkg:maven/org.springframework.ldap/spring-ldap-core","source":"GHSA-jrv5-8w28-4265"},{"ecosystem":"Maven","fixed":["3.3.8"],"introduced":["3.3.0"],"last_affected":[],"package":"org.springframework.ldap:spring-ldap-core","purl":null,"source":"GHSA-jrv5-8w28-4265"},{"ecosystem":"Maven","fixed":["3.3.8"],"introduced":["3.3.0"],"last_affected":[],"package":"org.springframework.ldap:spring-ldap-core","purl":"pkg:maven/org.springframework.ldap/spring-ldap-core","source":"GHSA-jrv5-8w28-4265"},{"ecosystem":"Maven","fixed":["4.0.4"],"introduced":["4.0.0"],"last_affected":[],"package":"org.springframework.ldap:spring-ldap-core","purl":null,"source":"GHSA-jrv5-8w28-4265"},{"ecosystem":"Maven","fixed":["4.0.4"],"introduced":["4.0.0"],"last_affected":[],"package":"org.springframework.ldap:spring-ldap-core","purl":"pkg:maven/org.springframework.ldap/spring-ldap-core","source":"GHSA-jrv5-8w28-4265"}],"prev":{"headline":"Spring Data KeyValue - SpEL Injection vulnerability in SpelPropertyComparator","id":"CVE-2026-41719"},"products":["Spring LDAP"],"published":"2026-06-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"total"},"state":"PUBLISHED","updated":"2026-06-23","vendors":["Spring"]},"summary":"Attackers can bypass authentication in Spring LDAP by providing a valid username with an empty or null password, gaining unauthorized access.","url":"https://insights.sbomify.com/CVE-2026-41720/"}
