Coolify before 4.1.1 contains an information disclosure vulnerability that allows unauthenticated attackers to enumerate application names across all teams via manual GitHub, GitLab, Bitbucket and Gitea webhooks. Attackers can send a repository name of % or empty with a common branch like main, exploiting unescaped LIKE wildcards to receive every matching application name before signature verification.
