AI Analysis
Technical Summary
YesWiki before version 4.6.7 contains a missing authorization vulnerability (CWE-862) in its attachment download handler. This vulnerability allows unauthenticated attackers to bypass page read access control lists (ACLs) by sending requests to the download handler with a known page tag and file parameter. As a result, attackers can retrieve confidential attachments from pages that are intended to be read-restricted.
Potential Impact
An attacker without any authentication can access confidential attachments from restricted pages, potentially leading to unauthorized disclosure of sensitive information. The vulnerability does not affect integrity or availability but impacts confidentiality significantly.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch links or vendor advisories are provided, users should monitor official YesWiki channels for updates and apply any forthcoming patches promptly. Until a fix is available, restrict access to the affected service or implement additional access controls at the network level if possible.
