CVE-2026-22688
CriticalSummary
WeKnora prior to version 0.2.5 has a command injection vulnerability that allows authenticated users to inject stdio_config.command/args into MCP stdio settings, causing the server to execute subprocesses using these injected values. This issue has been patched in version 0.2.5.
Risk Assessment
An authenticated user can execute arbitrary commands on the server, potentially leading to privilege escalation and system integrity compromise.
Recommendation
Upgrade WeKnora to version 0.2.5 or later, which contains the fix.

WeKnora before 0.8.2 contains a server-side request forgery vulnerability in isRestrictedIP() that misclassifies NAT64-prefixed IPv6 addresses as public. Authenticated attackers can supply URLs resolving to NAT64 encodings of internal addresses via web_fetch or URL-based knowledge import to reach internal services or cloud metadata endpoints.
- CVE-2026-91750Medium
WeKnora before 0.7.0 fails to re-validate HTTP redirect targets in the POST /api/v1/knowledge-bases/:id/knowledge/url endpoint when downloading documents from user-supplied URLs. Authenticated attackers can bypass initial SSRF validation by supplying a public URL that redirects to internal network addresses, allowing access to internal services and cloud metadata.
