In addition, the attacker must  have write access to a \nconfiguration file. Alternatively, the attacker could inject a malicious \nenvironment variable pointing to a malicious configuration file. In both \ncases, the attack requires existing privilege.\n\nCVE-2026-10532: Logback deserialization whitelist bypass for Proxy objects\n\nCVE-2026-1225: ACE vulnerability in configuration file processing  by QOS.CH logback-core up to and including version 1.5.24 in Java applications, allows an attacker to instantiate classes already present on the class path by compromising an existing logback configuration file.\n\n\n\n\nThe instantiation of a potentially malicious Java class requires that said class is present on the user's class-path. In addition, the attacker must  have write access to a \nconfiguration file. However, after successful instantiation, the instance is very likely to be discarded with no further ado.\n\nCVE-2026-9828: Logback deserialization whitelist bypass for java.lang and java.util\n\nThis patched artifact is a drop-in replacement for ch.qos.logback:logback-core 1.2.11 from Maven Central.","status":"published","published":"2026-10-12T16:52:49Z","modified":"2026-10-27T04:13:05.495206116Z","cvss":[{"version":"4.0","score":5.9,"vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:P/VC:L/VI:H/VA:L/SC:L/SI:H/SA:L/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:X/AU:X/R:X/V:X/RE:L/U:Clear","level":"medium"}],"updated_at":"2026-11-02T15:52:58.636919Z"},{"id":"ROOT-APP-MAVEN-CVE-2024-12798","title":"CVE-2024-12798 in io.root.ch.qos.logback:logback-core - Patched by Root","description":"Root has patched CVE-2024-12798 in the io.root.ch.qos.logback:logback-core package for Root:Maven.
