Prior to 1.4.2, interactive TUI row formatters pass Caddy access-log fields, particularly the request URI, through the `fitCellLeft` render helper without neutralizing terminal escape or control sequences. An unauthenticated remote client can place ANSI, OSC, or CSI control bytes in an ordinary HTTP request target. Caddy JSON-escapes those bytes, `ParseLogLine` decodes them back into raw controls, and the formatters concatenate them into `View()` output reaching `os.Stdout`. When the operator views the default `Logs` tab, the terminal interprets these sequences, allowing monitoring-dashboard spoofing, clipboard hijacking through `OSC 52`, and window-title spoofing through `OSC 0/2`. This works even with a loopback-only log listener because the input arrives through normal Caddy access logs. `Certificates` and `Routes` share secondary unneutralized render sinks. The `--json`, `--once`, and daemon `--expose` modes are unaffected because they do not render an interactive terminal. Consequences depend on the terminal emulator and usually require further operator action to escalate; this is not general-purpose remote code execution. This issue is fixed in version 1.4.2.","score":4.7,"severity":"medium","published":"2026-10-28T19:44:41.999Z","modified":"2026-10-29T18:31:49.122Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"alexandre-daubois","name":"ember","platforms":[],"versions":[{"version":"< 1.4.2","status":"affected"}],"cpes":[],"source":"GitHub_M","url":"https://www.cve.org/CVERecord?id=CVE-2026-54162"}],"remediation":[],"references":["https://github.com/alexandre-daubois/ember/security/advisories/GHSA-x3g7-qrwc-f6c5","https://github.com/alexandre-daubois/ember/commit/fcb7160e58dba58d6f9b5033cc312fdedc8c9f6b","https://github.com/alexandre-daubois/ember/releases/tag/v1.4.2"],"sources":[{"name":"CVE","id":"CVE-2026-54162","modified":"2026-10-29T18:31:49.122Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-54162"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N","score":4.7}],"sourceAffected":[],"observedAt":"2026-10-29T18:49:16.921Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T00:20:33.177Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-10-29T18:50:32.712Z","attemptedAt":"2026-10-29T18:50:32.712Z"},{"source":"GHSA","status":"available","checkedAt":"2026-10-29T18:50:32.341Z","attemptedAt":"2026-10-29T18:50:32.341Z"},{"source":"EUVD","status":"available","checkedAt":"2026-10-29T18:50:31.791Z","attemptedAt":"2026-10-29T18:50:31.791Z"},{"source":"EPSS","status":"available","checkedAt":"2026-10-29T18:50:32.715Z","attemptedAt":"2026-10-29T18:50:32.715Z"}],"evidence":[{"source":"ENISA EUVD","id":"EUVD-2026-112411","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-112411","modified":"Oct 28, 2026, 7:44:41 PM","score":4.7,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N","checkedAt":"2026-10-29T18:50:31.791Z"},{"source":"GitHub Advisory Database","id":"GHSA-x3g7-qrwc-f6c5","url":"https://github.com/advisories/GHSA-x3g7-qrwc-f6c5","modified":"2026-08-20T18:36:03Z","score":4.7,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N","checkedAt":"2026-10-29T18:50:32.341Z"},{"source":"NVD","id":"CVE-2026-54162","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54162","modified":"2026-10-29T16:19:37.750","score":4.7,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N","checkedAt":"2026-10-29T18:50:32.712Z"},{"source":"FIRST EPSS","id":"CVE-2026-54162","url":"https://www.first.org/epss/","probability":0.00251,"percentile":0.16454,"date":"2026-10-29","checkedAt":"2026-10-29T18:50:32.715Z"}],"aiSummary":{"text":"Ember, a terminal dashboard for Caddy servers, has a vulnerability in versions prior to 1.4.2 where unauthenticated clients can inject terminal escape sequences into the operator's TUI, potentially allowing monitoring-dashboard spoofing and clipboard hijacking.
