CVE-2026-56783
Parseable < 2.9.2 - Cleartext Credential Exposure in Notification Target API
Description
Parseable before 2.9.2 contains an information disclosure vulnerability in the notification-target API endpoints that returns webhook tokens and basic-auth credentials in cleartext due to commented-out secret-masking functionality. Any authenticated user with the GetAlert action, including low-privilege reader roles, can recover credentials and internal endpoint URLs for all configured notification targets by querying GET /api/v1/targets or related endpoints.
