CVE-2026-50000
SecureDrop: API session token reuse against the Journalist Interface web UI
Description

SecureDrop is an open-source whistleblower submission system that media organizations can use to securely accept documents from, and communicate with anonymous sources. From 2.5.0 until 2.16.0, the `Journalist Interface` can accept an `API session` token against the `web UI` because its `SessionInterface` keeps a mutable session key prefix that changes with each request and persists across requests. API and web sessions were separated in `Redis` starting in version 2.5.0, but prefix corruption confuses those session namespaces. An attacker who already has access to the secret `Journalist Interface` onion address, the required authentication access and a recent nonexpired `API session` token can reuse that token against the `web UI` until its natural expiry, at most eight hours. The corrupted prefix can also prevent logout from deleting the correct `Redis` session, although normal expiry still applies. A compromised journalist can access encrypted submissions and perform broad actions on source submissions, but this issue does not expose plaintext submissions or affect the running system's availability. This issue is fixed in version 2.16.0.
