A high-severity vulnerability tracked as CVE-2026-62327 affects decolua's 9Router through version 0.4.41, allowing remote attackers to retrieve plaintext API keys for all connected AI provider accounts without authentication. The flaw stems from missing authentication middleware on the Next.js API route /api/usage/stats, enabling a single unauthenticated request to disclose sensitive account data.
In addition to API keys, the exposed response can include token counts, cost breakdowns, and request metadata, creating risks of unauthorized use of linked AI services, billing fraud, and quota exhaustion. The issue is classified as an information disclosure vulnerability tied to CWE-306 and CWE-522, with a CVSS 3.1 score reflecting high impact from network-accessible exploitation requiring no privileges or user interaction.
