Alternatively, the attacker could inject a malicious \nenvironment variable pointing to a malicious configuration file. In both \ncases, the attack requires existing privilege.","cvss_v4":{"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/RE:L/U:Clear","score":5.9},"cvss_v3":null,"cwes":["CWE-917"],"references":["https://logback.qos.ch/news.html#1.3.15","https://logback.qos.ch/news.html#1.5.13"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:57:56.913276502+00:00"},"epss":{"cve":"CVE-2024-12798","score":0.00458,"percentile":0.397,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-pr98-23f8-jwxv","url":"https://osv.dev/vulnerability/GHSA-pr98-23f8-jwxv","summary":"QOS.CH logback-core Expression Language Injection vulnerability","modified":"2026-09-10T03:50:21.783184580Z","packages":[{"ecosystem":"Maven","name":"ch.qos.logback:logback-core","purl":"pkg:maven/ch.qos.logback/logback-core","ranges":[">=1.4.0 <1.5.13"],"fixed":["1.5.13"]},{"ecosystem":"Maven","name":"ch.qos.logback:logback-core","purl":"pkg:maven/ch.qos.logback/logback-core","ranges":["<1.3.15"],"fixed":["1.3.15"]}]}],"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).
