Description
changedetection.io is a free open source web page change detection tool. Prior to 0.54.7, the `jq:` and `jqraw:` include filter expressions allow use of the jq `env` builtin, which reads all process environment variables and stores them as the watch snapshot. An authenticated user (or unauthenticated user when no password is set, the default) can leak sensitive environment variables including `SALTED_PASS`, `PLAYWRIGHT_DRIVER_URL`, `HTTP_PROXY`, and any secrets passed as env vars to the container. Version 0.54.7 patches the issue.
