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.","state":0,"publishedAt":"2026-10-28T20:18:00.743+00:00","modifiedAt":"2026-10-28T20:18:00.743+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N","score":4.7,"severity":"MEDIUM"}],"references":["https://github.com/alexandre-daubois/ember/commit/fcb7160e58dba58d6f9b5033cc312fdedc8c9f6b","https://github.com/alexandre-daubois/ember/releases/tag/v1.4.2","https://github.com/alexandre-daubois/ember/security/advisories/GHSA-x3g7-qrwc-f6c5"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-54162","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Received","weaknesses":["CWE-150"],"productCriteria":[],"sourceDates":{"published":"2026-10-28T20:18:00.743","lastModified":"2026-10-28T20:18:00.743"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
