The endpoint exposes an observable response discrepancy when processing ID values. A request submitted with a nonexistent ID returns a distinct error response code from one submitted with a valid, registered ID, allowing an attacker holding a valid access token - but without further authentication or authorization - to distinguish valid ID values from the full 10-digit numeric search space. Combined with the absence of meaningful rate limiting on this endpoint, this discrepancy constitutes an enumeration oracle, enabling an attacker to discover registered devices at scale.

CVE-2026-111056——
——0FOSSBilling is an open source billing and client-management platform. From 0.1.0 until 0.8.7, the unauthenticated POST /api/guest/client/create endpoint reveals whether a submitted email belongs to a registered client because guest signup returns a distinct unredacted error when the submitted email already exists. The trigger is an unauthenticated request to POST /api/guest/client/create with a target email address. An attacker can compare the guest-signup response for a target email to determine whether the email belongs to an existing FOSSBilling client. Box\Mod\Client\Api\Guest::create returns the error after Client\Service::clientAlreadyExists finds a matching record, and the API response exposes that exception message without redaction. This issue is fixed in version 0.8.7.1dCVE-2026-1118875.3 MED16.7%
——5phpMyFAQ before 4.1.9 and 4.2.0-alpha before 4.2.0-beta contains an account enumeration vulnerability that allows unauthenticated attackers to confirm registered display names and emails via a distinct HTTP 409 response. Attackers can submit guest comments to the comment create endpoint with candidate user and mail values to link names to emails for targeted phishing.2dCVE-2026-141777.5 HIG14.7%
——4Observable response discrepancy vulnerability in IKAS Technology Inc. Ikas E-Commerce Infrastructure allows Account Footprinting.

——3Nezha from 1.7.0 before 2.3.15 contains an information disclosure vulnerability that allows authenticated members to enumerate other tenants' server IDs through differential responses. Attackers can sweep sequential IDs against getServerConfig and setServerConfig, distinguishing 'permission denied' from success payloads to map other users' servers.4dCVE-2026-1112359.1 CRI30.1%
——9An authorization bypass vulnerability exists in the REST API of multiple versions of OpenNMS Meridian and Horizon. The /rest/** Spring Security filter chains authorize requests with intercept-url rules that name the HTTP method as an uppercase token, compare the method case-sensitively, and have no terminal deny rule. A request that uses a non-canonical (for example lowercase) method token matches no rule and is processed without authentication. A remote, unauthenticated attacker can read the monitored inventory and can create, modify, or delete resources through the REST API, which includes injecting events to fabricate or suppress alarms. The /rest/alarms chain has the same missing deny rule and discloses whether an alarm exists through a difference in the response. The fix adds a terminal deny rule to each REST filter chain.
The solution is to upgrade to Meridian 2024.3.14, 2025.0.11, 2026.0.1 and Horizon 36.0.5 or newer. Meridian and Horizon installation instructions state that they are intended for installation within an organization's private networks and should not be directly accessible from the Internet.4dCVE-2026-1103105.3 MED42.2%
——13A remote user who can read encrypted objects in the S3 bucket can force a padding downgrade by altering the padding scheme recorded in an object's metadata to legacy PKCS#1 v1.5. Since this padding scheme is susceptible to the well-known Bleichenbacher attack, the user can use a PKCS#1 v1.5 padding oracle to recover the RSA-wrapped envelope key and decrypt the object.
To remediate this issue, we recommend that users upgrade to version 3.2.2 or 4.0.3. The 1.x and 2.x lines will not be patched, users of those lines need to migrate to 3.2.2 or 4.0.3.4d
