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.
