Short explanation
Wekan is vulnerable to ReDoS because user-controlled inputs are passed to new RegExp() without escaping regular-expression metacharacters [S0]. This allows authenticated users to submit expressions that consume database CPU and degrade service [S0].
Authenticated users can submit catastrophic backtracking expressions that exhaust database CPU resources, leading to service degradation or denial of service for other users [S0].
What should be done?
- Upgrade Wekan to version 11.11 or later [S0]
- Follow vendor advisories for mitigation steps [S0]
Chain of evidence and sources
Wekan içinde kullanıcı girdilerinin filtrelenmemesi ReDoS zafiyetine yol açmaktadır [S0].
Sorun MongoDB tabanlı dağıtımlarda PCRE2 değerlendirmesi nedeniyle ortaya çıkmaktadır [S0].
Show the technical text from the sources
Wekan is open source kanban built with Meteor. Prior to 11.11, the user-search publication in server/publications/users.js and the searchUsers method in server/models/users.js pass authenticated user-controlled searchTerm and query values to new RegExp() without escaping regular-expression metacharacters. MongoDB-backed deployments evaluate the resulting patterns with PCRE2, allowing a logged-in user to submit catastrophic-backtracking expressions that consume database CPU and degrade or deny service to other users; searchUsers additionally requires board membership or site-admin status. The FerretDB v1 / RE2 unaffected configuration is not practically affected by catastrophic backtracking. This issue is fixed in version 11.11.
