Unauthenticated file disclosure via retained guest permissions
Published Aug 22, 2025 · Updated Aug 22, 2025
Information disclosure in Liferay Portal and DXP affected releases allows remote attackers to read object-entry uploads by URL. ObjectDefinitionDeployerImpl.upload() creates a temporary DLFileEntry without revoking the guest role's DOWNLOAD permission, leaving its content URL reachable. No account is required, but another user must upload a file and its URL must become known; the bounded impact is disclosure of that file's contents.
