Information Disclosure in apprise (CVE-2026-59180)

Summary

Vulnerability in apprise (CVE-2026-59180). Risk of unauthorized operations or information disclosure. Exploitable via Authorization. Mitigation: upgrade to 1.11.0 or later.

Original description

The description as published by the source.

Summary

Apprise's HTTP-based notification plugins and its HTTP attachment / config loaders (apprise/attachment/http.py, apprise/config/http.py) follow HTTP 3xx redirects by default and re-send the user-configured auth headers and query parameters on the redirected request. If an operator-configured destination is later compromised (service takeover, malicious update), or an attacker holds a MITM position on an unprotected network path, that destination can return a 302 Location: to an arbitrary host and Apprise forwards the user's secret (X-Gotify-Key, Authorization, bearer tokens in query, custom +Header= values) to that cross-origin host. The attacker does not need to control the original Apprise URL — only the response from a destination the operator already trusts.

This is the application-layer analogue of urllib3 GHSA-34jh-p97f-mpxf / CVE-2026-44431 ("Proxy-Authorization forwarded across cross-origin redirect").

Affected versions

All releases up to and including v1.10.0 (latest PyPI release as of filing, 2026-04-26). Fixed in v1.11.0 (released 2026-05-29), which includes PR #1610 (merged 2026-05-16, commit 68c0aef218055e4586cf4605fd6b56358f5f462d).

Information disclosure (CWE-200) exists in apprise. Attackers reach the vulnerable code path via Authorization without authentication.

📍 Affected scope

Check the vendor advisory for the affected versions of apprise. Attack surface: Authorization / requests / custom_json / custom_xml.

🔥 Severity

Severity: Low (CVSS 3.1/10). Risk of unauthorized operations or information disclosure.

🔧 How to fix

Update to 1.11.0.

🛡️ Workaround

Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.

🔍 Detection

Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r 'apprise' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify 
    grep -r 'apprise' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で apprise を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Apply patch patch 
    Upgrade apprise to 1.11.0

    ステージング環境で 1.11.0 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスを含めること。

  3. 3
    Post-deployment verification verify 
    Confirm patched version is live in production

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
