CVE-2026-109204

LogicalDOC Community Edition through 9.3 contains a username enumeration vulnerability that allows unauthenticated attackers to identify valid accounts because the AvatarServlet (/avatar) performs no session validation.

LogicalDOC Community Edition through 9.3 contains a missing authorization vulnerability in the ConvertPdf servlet that allows authenticated users to download restricted PDF documents. Attackers can enumerate sequential docId values and use the version parameter to retrieve any PDF and its versions from folders they cannot access.

LogicalDOC Community Edition through 9.3 contains a missing authorization vulnerability in the zip-export servlet that allows authenticated users to export restricted folders by supplying a folderId parameter. Attackers can request /zip-export with a restricted folder ID, since ZipExport.addFolderDocuments() skips READ and DOWNLOAD permission checks, to download all of its documents in a ZIP archive.

LogicalDOC Community Edition through 9.3 contains a server-side request forgery vulnerability in the default-enabled XMLConverter that fetches xml-stylesheet href URLs without scheme or host allowlisting. Authenticated users can upload XML documents whose stylesheet href points to internal http, ftp, file, or jar URLs, forcing server requests and applying attacker-controlled XSLT during conversion.

LogicalDOC Community Edition through 9.3 contains an HQL injection vulnerability in DocumentsDataServlet that allows authenticated users to manipulate queries via the unvalidated indexed parameter. Attackers with read access to any folder can inject boolean HQL expressions to bypass folder scope and read-permission checks, listing restricted document metadata and extracting database contents.

LogicalDOC Community Edition through 9.3 contains a sql injection vulnerability that allows authenticated users to execute crafted SQL via the firstLetter parameter of TagsDataServlet. Low-privileged attackers can inject UNION SELECT statements returned in the XML tag list to read usernames, email addresses and password hashes from ld_user.

In LogicalDOC Community Edition up to 9.2.1, the admin login page (/login.jsp) lacks proper restriction of excessive authentication attempts. The attack has high complexity and is difficult to exploit, but a public exploit is available.

The Automation Scripting functionality can be exploited by attackers to run arbitrary system commands on the underlying operating system. An account with administrator privileges or that has been explicitly granted access to use Automation Scripting is needed to carry out the attack. Exploitation of this vulnerability would allow an attacker to run commands of their choosing on the underlying operating system of the web server running LogicalDOC.
