SCA: security update for github.com/alexandre-daubois/ember (GHSA-x3g7-qrwc-f6c5)

medium Tenable Self-Hosted Container Security Plugin ID 446152

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Ember is a real-time terminal dashboard for Caddy servers with FrankenPHP support. 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. (CVE-2026-54162)

Solution

Update the github.com/alexandre-daubois/ember library and its related packages to version 1.4.2 or later.
