CVE-2026-59180 caronc CVE debrief

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.
