Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Insecure endpoints and missing signature checks allowed unauthorized users to join arbitrary tenants without approval or valid signatures. Guarding these operations is critical to preventing tenant isolation breaches.
Auth Bypass: Lack of permission enforcement on sensitive administrative endpoints allowed unauthorized users to trigger session terminations (/forceLogout).
SSRF: The processing of remote images via WordUtil.addImage was vulnerable to SSRF because it failed to validate the destination IP address and followed malicious HTTP redirects.
