Who should care

Users of Apprise open source library versions prior to 1.11.0 should update to the latest version to prevent potential security risks. This includes operators, administrators, and security teams responsible for maintaining and securing systems that utilize the Apprise library. Additionally, vulnerability management teams should review the CVE record and NVD entry for more information on the vulnerability and its potential impact.

Technical summary

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. This allows a compromised trusted destination or on-path attacker to receive secrets such as Authorization headers, bearer tokens, custom headers, and service keys. The vulnerability is fixed in version 1.11.0, and users should review the official advisory for more details on the affected components and potential impact.

Defensive priority

Medium

Recommended defensive actions

  • Update Apprise open source library to version 1.11.0 or later

  • Monitor for potential security risks and anomalies
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
