Security
- Enforce guest ownership and server assignment across Proxmox endpoints
(VM/LXC actions, firewall, backups, tasks, bulk operations, deploy,
LXC/ISO creation, golden template) and WebSocket channels
- Keep the panel's PVE root ticket server-side for consoles; single-use
WebSocket tickets instead of the JWT in URLs; re-check access on open
WebSocket bridges
- Validate identifiers that reach Proxmox API paths and node shell
commands; reject backup archives / foreign volumes in create requests
- Close privilege escalation in user management, TOTP replay, reset-link
poisoning, X-Forwarded-For spoofing, stored XSS (group icons, SVG logos)
- SSH host key pinning (TOFU), encrypted 2FA seeds and notification
secrets, password changes end other sessions, redact secrets in logs
- Quotas count in-flight creations; 2FA failures count toward lockout
Fixes
- Consoles on non-default API ports, large App Store/script files,
interrupted tasks after restart, impersonation lost on token refresh,
HTTPExceptions swallowed into 500s, WebSocket client reconnects
Performance and process
- Fewer DB writes and queries on hot paths, lazy-loaded locales and
heavy pages, off-loop blocking work, indexes (migrations 44-46)
- Deploy waits for backend tests and frontend build; frontend checks
workflow; API bound to loopback without the SSL profile
- Add password field to UserUpdate schema for password change on edit
- Implement password validation in update_user endpoint
- Add i18n translations for password validation errors (ru/en)
- Update SecurityService.validate_password to support language parameter
- Add GitHub icon and repository name 'pvemanager' to header button
- Fix internal server error when updating user password
- Clean up hardcoded translations in frontend
