CVE-2026-65319

Summary

Feedbin (commit 739884a) contains an unauthenticated information disclosure vulnerability that allows unauthenticated attackers to retrieve private article content by sending requests to the entries text API endpoint, which skips the authorization before-action filter entirely. Attackers can iterate sequential integer entry IDs through the GET /api/v2/entries/:id/text endpoint to enumerate and extract plain-text content of all stored articles, including private newsletter content, personal page-saves, and articles from any user's private subscriptions.
