From versions 1.15.0 to 8.2610.0, rsyslog's omfile dynaFile facility intentionally allows templates to generate flexible output paths. This supports valid deployments that route logs into different directories or use dynamically generated file names. A deployment becomes unsafe when a dynaFile template uses a value influenced by untrusted input as a path component without explicit secure-path handling. In that configuration, the rendered path can escape the operator's intended log directory. This is not limited to the RFC5424 HOSTNAME field. Any untrusted value that reaches a dynaFile path component can create the condition. At time of publication, there are no publicly available patches.","score":8.1,"severity":"high","published":"2026-10-22T13:32:56.695Z","modified":"2026-10-29T02:15:30.165Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"rsyslog","name":"rsyslog","platforms":[],"versions":[{"version":">= 1.15.0, <= 8.2610.0","status":"affected"}],"cpes":[],"source":"GitHub_M","url":"https://www.cve.org/CVERecord?id=CVE-2026-92709"}],"remediation":[],"references":["https://github.com/rsyslog/rsyslog/security/advisories/GHSA-xmp9-244p-5ggv"],"sources":[{"name":"CVE","id":"CVE-2026-92709","modified":"2026-10-29T02:15:30.165Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-92709"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1}],"sourceAffected":[],"observedAt":"2026-10-29T14:48:49.504Z","kev":{"status":"not-listed","checkedAt":"2026-10-31T12:15:32.680Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-10-29T08:25:32.486Z","attemptedAt":"2026-10-29T08:25:32.486Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-10-29T08:25:33.203Z","attemptedAt":"2026-10-29T08:25:33.203Z"},{"source":"EUVD","status":"available","checkedAt":"2026-10-29T08:25:34.626Z","attemptedAt":"2026-10-29T08:25:34.626Z"},{"source":"EPSS","status":"available","checkedAt":"2026-10-29T08:25:32.431Z","attemptedAt":"2026-10-29T08:25:32.431Z"}],"evidence":[{"source":"FIRST EPSS","id":"CVE-2026-92709","url":"https://www.first.org/epss/","probability":0.00296,"percentile":0.22225,"date":"2026-10-28","checkedAt":"2026-10-29T08:25:32.431Z"},{"source":"NVD","id":"CVE-2026-92709","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92709","modified":"2026-10-29T04:18:43.610","score":8.1,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","checkedAt":"2026-10-29T08:25:32.486Z"},{"source":"ENISA EUVD","id":"EUVD-2026-108168","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-108168","modified":"Oct 29, 2026, 2:15:30 AM","score":8.1,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","checkedAt":"2026-10-29T08:25:34.626Z"}],"aiSummary":{"text":"Rsyslog versions 1.15.0 to 8.2610.0 have a path traversal weakness, allowing arbitrary file write as root when a dynaFile template uses untrusted input without secure-path handling.
