CVE-2026-32774Network attack vector

Stored XSS via unsanitized comment hypertext

Published Mar 14, 2026 · Updated Mar 14, 2026

Stored cross-site scripting in Vulnogram 1.0.0 allows remote authenticated users to execute JavaScript in viewers' browsers via comments. The comment routes write req.body.text directly to the hypertext field, which Pug renders with unescaped interpolation without server-side sanitization. Posting a comment requires an authenticated account, and the script runs when another user views the affected entry, exposing that browser context rather than the server.
