In addition, the attacker must\u00A0 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\nPlease note that in logack version 1.5.37 conditional processing using Janino was removed.","state":0,"publishedAt":"2026-06-24T05:41:32.197+00:00","modifiedAt":"2026-07-01T11:05:37.718+00:00","affected":[{"ecosystem":"Vendor product","name":"Logback-core","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"QOS.CH Sarl\",\n                    \"product\": \"Logback-core\",\n                    \"platforms\": [\n                        \"Java\"\n                    ],\n                    \"modules\": [\n                        \"logback-core\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0.9.20\",\n                            \"lessThanOrEqual\": \"1.5.36\",\n                            \"versionType\": \"maven\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"1.5.37\",\n                            \"versionType\": \"maven\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"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/S:P/AU:N/RE:M/U:Green","score":7,"severity":"HIGH"}],"references":["https://logback.qos.ch/news.html#1.5.37"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-13006","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-13006","identifiers":["CVE-2026-13006"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
