    Disclosures

    Supabase template hard-codes postgres on 0.0.0.0:5432; Zulip ships secret_key: changeme and HTTP-only transport. CVE-2026-16503 leaves PostgreSQL bound to 0.0.0.0:5432 with password postgres; CVE-2026-16504 ships Zulip with secret_key: changeme and HTTP-only transport. CERT/CC's VU#243636 rates both as SSVC Technical Impact = Total, and VPS dot org is unreachable with no patch. CVE-2026-16503 hands remote attackers PostgreSQL superuser credentials on a database published to 0.0.0.0:5432. CVE-2026-16504 does the same trick for Zulip: secretkey: changeme, default database password zulip, and DISABLEHTTPS=True. CERT/CC's VU#243636 classifies both as Technical Impact = Total under SSVC: adversary gets total control of the affected service or total disclosure of its data. https://news.ojobit.com/story/vpsorg-one-click-templates-secret-backdoors-4dfe24
