{"id":"CVE-2026-59180","summary":"Apprise forwards configured auth headers across cross-origin HTTP redirects","details":"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.","aliases":["GHSA-856c-92hv-3vxx"],"modified":"2026-09-09T18:26:43.298351499Z","published":"2026-07-10T16:02:15.409Z","related":["openSUSE-SU-2026:21789-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59180.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-200","CWE-601"]},"references":[{"type":"WEB","url":"https://github.com/caronc/apprise/releases/tag/v1.11.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59180.json"},{"type":"ADVISORY","url":"https://github.com/caronc/apprise/security/advisories/GHSA-856c-92hv-3vxx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59180"},{"type":"FIX","url":"https://github.com/caronc/apprise/commit/68c0aef218055e4586cf4605fd6b56358f5f462d"},{"type":"FIX","url":"https://github.com/caronc/apprise/pull/1610"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/caronc/apprise","events":[{"introduced":"0"},{"fixed":"68c0aef218055e4586cf4605fd6b56358f5f462d"},{"fixed":"158c4e1febc3e6093b0f357776b315a90c8a89b5"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.11.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.10.0","v1.9.9","v1.9.8","v1.9.7","v1.9.6","v1.9.5","v1.9.4","v1.9.3","v1.9.2","v1.9.1","v1.9.0","1.9.0","v1.8.1","v1.8.0","v1.7.6","v1.7.5","v1.7.4","v1.7.3","v0.8.8","v1.7.2","v1.7.1","v1.7.0","v1.6.0","v1.5.0","v1.4.5","v1.4.0","v1.3.0","v1.2.1","v1.2.0","v1.1.0","v1.0.0","v0.9.9","v0.9.8.3","v0.9.8.2","v0.9.8.1","v0.9.8","v0.9.7","v0.9.6","v0.9.5.1","v0.9.5","v0.9.4","v0.9.3","v0.9.2","v0.9.1","v0.9.0","v0.8.9","v0.8.7","v0.8.6","v0.8.5","v0.8.4","v0.8.3","v0.8.2","v0.8.1","v0.8.0","v0.7.9","v0.7.8","v0.7.7","v0.7.6","v0.7.5","v0.7.4","v0.7.3","v0.5.2","v0.5.0","v0.0.9","v0.0.8","v0.0.7"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-59180.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N"}]}
