{"id":"CVE-2026-49996","state":"PUBLISHED","title":"securedrop-proxy origin limitation can be bypassed with redirects","description":"SecureDrop Client is a desktop app for journalists to securely communicate with sources and handle submissions on the SecureDrop Workstation. Prior to version 1.3.1, a malicious SecureDrop Server could bypass securedrop-proxy's origin limitation by responding with cross-origin redirects. SecureDrop Server itself has multiple layers of built-in hardening, and is a dedicated physical machine exposed on the internet only via Tor hidden services for the Source and Journalist interfaces, and optionally via remote SSH access over another Tor hidden service. A newsroom's SecureDrop Workstation communicates only with its own dedicated SecureDrop Server. Version 1.3.1 fixes the issue.","publishedAt":"2026-08-20T18:55:57.513Z","updatedAt":"2026-08-20T19:48:57.931Z","severity":{"score":3.7,"label":"Low","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["freedomofpress securedrop-client"],"affected":[{"vendor":"freedomofpress","product":"securedrop-client","versions":[{"version":"< 1.3.1","status":"affected"}]}],"references":["https://github.com/freedomofpress/securedrop-client/security/advisories/GHSA-6qxc-pcfg-v6qv","https://github.com/freedomofpress/securedrop-client/commit/3c9769b12fb115768d43617635fd2e00737ef2f7"],"weaknesses":["CWE-601"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/49xxx/CVE-2026-49996.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-49996","state":"PUBLISHED","datePublished":"2026-08-20T18:55:57.513Z","dateUpdated":"2026-08-20T19:48:57.931Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-02T18:30:51.283Z"},"containers":{"cna":{"title":"securedrop-proxy origin limitation can be bypassed with redirects","descriptions":[{"lang":"en","value":"SecureDrop Client is a desktop app for journalists to securely communicate with sources and handle submissions on the SecureDrop Workstation.
