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":"2026-10-28T19:44:41.999+00:00","modifiedAt":"2026-10-29T18:31:49.122+00:00","affected":[{"ecosystem":"Vendor product","name":"ember","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"alexandre-daubois\",\n                    \"product\": \"ember\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.4.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","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/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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54162","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54162","identifiers":["CVE-2026-54162"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
