{"id":"DEBIAN-CVE-2026-13006","details":"ACE vulnerability in conditional configuration file processing  by QOS.CH logback-core up to and including version 1.5.36 in Java applications, allows an attacker to execute arbitrary code circumventing existing protections against CVE-2025-11226 by compromising an existing logback configuration file or by injecting an environment variable before program execution.    A successful attack requires the presence of Janino library to be present on the user's class path. In addition, the attacker must  have write access to a  configuration file. Alternatively, the attacker could inject a malicious  environment variable pointing to a malicious configuration file. In both  cases, the attack requires existing privilege.  Please note that in logack version 1.5.37 conditional processing using Janino was removed.","modified":"2026-09-14T17:01:54.206520126Z","published":"2026-06-24T07:16:27.127Z","upstream":["CVE-2026-13006"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-13006"}],"affected":[{"package":{"name":"logback","ecosystem":"Debian:12","purl":"pkg:deb/debian/logback?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:1.2.11-3","1:1.2.11-4","1:1.2.11-5","1:1.2.11-6","1:1.6.3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13006.json"}},{"package":{"name":"logback","ecosystem":"Debian:13","purl":"pkg:deb/debian/logback?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:1.2.11-6","1:1.6.3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13006.json"}},{"package":{"name":"logback","ecosystem":"Debian:14","purl":"pkg:deb/debian/logback?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:1.2.11-6","1:1.6.3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13006.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:N/SC:L/SI:L/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:P/AU:N/R:X/V:X/RE:M/U:Green"}]}
