Description
Apprise is an open source library which allows you to send a notification to almost all of the most popular notification services available. Prior to 1.11.0, Apprise HTTP-based notification plugins and HTTP attachment and config loaders in apprise/attachment/http.py and apprise/config/http.py follow HTTP redirects by default and resend user-configured auth headers and query parameters on the redirected request, allowing a compromised trusted destination or on-path attacker to receive secrets such as Authorization headers, bearer tokens, custom headers, and service keys. This issue is fixed in version 1.11.0.
