Alert meAnalysisAIv1 – Mar 12, 2026
Server-Side Request Forgery in Wekan 8.32-8.33 allows authenticated users to force the server to make arbitrary HTTP requests by supplying malicious attachment URLs during board imports from JSON data or Trello. An attacker could exploit this to access internal network services, cloud metadata endpoints, or expose sensitive credentials without any URL validation occurring on the server side.

Technical ContextAI · show details
Classified as CWE-918 (Server-Side Request Forgery (SSRF)). Affects Wekan. Wekan is an open source kanban tool built with Meteor. Versions 8.32 and 8.33 are vulnerable to Server-Side Request Forgery (SSRF) via attachment URL loading. During board import in Wekan, attachment URLs from user-supplied JSON data are fetched directly by the server without any URL validation or filtering, affecting both the Wekan and Trello import flows. The parseActivities() and parseActions() methods extract user-controlled attachment URLs, which are then passed directly to Attachments.load

2DescriptionGitHub Advisory
Wekan is an open source kanban tool built with Meteor. Versions 8.32 and 8.33 are vulnerable to Server-Side Request Forgery (SSRF) via attachment URL loading. During board import in Wekan, attachment URLs from user-supplied JSON data are fetched directly by the server without any URL validation or filtering, affecting both the Wekan and Trello import flows. The parseActivities() and parseActions() methods extract user-controlled attachment URLs, which are then passed directly to Attachments.load() for download with no sanitization. This Server-Side Request Forgery (SSRF) vulnerability allows any authenticated user to make the server issue arbitrary HTTP requests, potentially accessing internal network services such as cloud instance metadata endpoints (exposing IAM credentials), internal databases, and admin panels that are otherwise unreachable from outside the network. This issue has been fixed in version 8.34.
Executive ViewAI
Wekan versions 8.32 and 8.33 contain a critical Server-Side Request Forgery vulnerability that could allow attackers to access internal network resources through malicious attachment URLs. Organizations running affected versions require immediate patching to prevent potential data exfiltration and lateral movement within internal infrastructure.
Apply vendor patch. If immediate patching is not possible: Implement WAF rules to block suspicious attachment URL patterns; restrict outbound network access from Wekan servers to internal subnets; disable attachment URL loading functionality; implement request validation and URL whitelisting for attachment sources.
