Improper input validation in Capgo
CVE-2026-56325
Capgo before 12.128.2 uses ILIKE pattern matching instead of exact matching for app_id lookup in the preview subdomain resolver, allowing underscore characters in app_id to act as SQL wildcards. Attackers can create apps with app_ids differing by one character at underscore positions to cause unintended pattern matches, breaking preview functionality for legitimate apps or causing app-id confusion.
