{"id":"CVE-2026-44305","summary":"Lemur: LDAP TLS certificate verification globally disabled enables credential interception","details":"Lemur manages TLS certificate creation. Prior to 1.9.0, when LDAP TLS is enabled (LDAP_USE_TLS = True), Lemur's LDAP authentication module unconditionally disables TLS certificate verification at the global ldap module level. This allows a man-in-the-middle attacker positioned between Lemur and the LDAP server to intercept all authentication credentials. This vulnerability is fixed in 1.9.0.","aliases":["GHSA-vr7c-r5gj-j3w5","PYSEC-2026-2590"],"modified":"2026-07-15T01:49:10.537848341Z","published":"2026-05-12T21:28:06.362Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-295"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44305.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44305.json"},{"type":"ADVISORY","url":"https://github.com/Netflix/lemur/security/advisories/GHSA-vr7c-r5gj-j3w5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44305"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/netflix/lemur","events":[{"introduced":"0"},{"fixed":"f59087a51b986595af49c7e1bc89913632c0d625"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.9.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v1.8.2","v1.8.1","v1.8.0","v1.7.0","v1.6.0","v1.5.0","v1.4.0","v1.3.2","v1.3.1","v1.3.0","v1.2.0","v1.1.0","v1.0.0","v0.11.0","v0.10.0","v0.9.0","v0.8.1","0.8.0","0.7.0","0.6.0","0.5.0","0.4.0","0.3.0","0.2.2","0.2.1","0.2","0.1.5","0.1.4","0.1.3","0.1.2","0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44305.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
