{"id":"DEBIAN-CVE-2026-103877","details":"Deserialization of Untrusted Data vulnerability in Apache Directory LDAP API.    A rogue/compromised LDAP server (or pre-TLS MITM) can answer a client's loadSchema() subschema search with a schema object that contains a serialized Java class, allowing some potential RCE.     This issue affects Apache Directory LDAP API: from 2.1.0 before 2.1.9.    Users are recommended to upgrade to version 2.1.9, which fixes the issue.","modified":"2026-10-08T10:00:30.259300857Z","published":"2026-10-02T10:17:06.437Z","upstream":["CVE-2026-103877"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-103877"}],"affected":[{"package":{"name":"apache-directory-api","ecosystem":"Debian:12","purl":"pkg:deb/debian/apache-directory-api?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.2-1","2.1.2-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-103877.json"}},{"package":{"name":"apache-directory-api","ecosystem":"Debian:13","purl":"pkg:deb/debian/apache-directory-api?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.2-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-103877.json"}},{"package":{"name":"apache-directory-api","ecosystem":"Debian:14","purl":"pkg:deb/debian/apache-directory-api?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.2-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-103877.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
