If you cannot patch yet, restrict external access to the /share/page/resource/ endpoint if possible, and monitor for unusual file access attempts. Follow vendor communications closely for official patches or mitigations.
Description
Hyland Alfresco allows unauthenticated attackers to read arbitrary files from protected directories (like WEB-INF) via the "/share/page/resource/" endpoint, thus leading to the disclosure of sensitive configuration files.
