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\nPlease note that in logack version 1.5.37 conditional processing using Janino was removed.","cvss_v4":{"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":7.0},"cvss_v3":null,"cwes":["CWE-20"],"references":["https://logback.qos.ch/news.html#1.5.37"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-13006","score":0.00175,"percentile":0.06982,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
