| Compare | XWiki | BookStack |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Docs-heavy enterprises | Self-hosters and homelab users |
| Who it's not for | Small teams wanting a simple shared wiki | Teams with nobody to run and patch a server |
| Privacy | Active exploitation of an unauthenticated RCE in 2025 plus further CVEs into 2026 . patch fast or use managed hosting.⁵ | Active project with frequent security releases . but multiple public CVEs, including auth bypasses and RCE, mean prompt patching is essential.⁵ |
| Support quality | Active forums; vendor support requires paid contract | Community-driven; no vendor support evidence found |
| Public sentiment | Power and value win fans, but recurring complaints call it too complex for simple needs and question its Confluence-parity.¹ | Users consistently praise BookStack's simplicity and structure for small teams, while flagging limited customization and its small-scale fit.11 |
| Biggest gotcha | Unauthenticated RCE (CVE-2025-24893) exploited in the wild; botnet hit 3,400+ instances. Patch immediately. | Repeated auth-bypass and RCE CVEs . you must patch quickly or stay exposed.⁵ |
