|
| Exploitation Conditions | Requires an authenticated LubeLogger account (any user who can edit at least one destination vehicle) on a version prior to 1.6.8, plus a multi-user or household-shared deployment where other users' records exist to be stolen - a single-user instance has no cross-user victim. The attacker supplies caller-controlled source recordIds belonging to another user to the DuplicateRecordsToOtherVehicles endpoint while naming a destination vehicleId they control; no special non-default configuration, no user interaction, and no admin/root role are needed. Limiting factors: valid credentials on the instance, knowledge or enumeration of victim recordIds, and the presence of other users' vehicle records. |
| Impact | The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N = 7.1 High) is internally consistent with the described flaw: a network-reachable, low-complexity IDOR requiring only a low-privileged authenticated account and no user interaction. The real-world risk is materially lower than the 7.1 headline for two reasons. First, exploitation requires an authenticated account on the same LubeLogger instance AND the presence of other users' records worth stealing - this only matters on multi-user / household-shared deployments; a single-user self-hosted instance has no cross-user victim. Second, the primary impact is confidentiality (C:H - copying another user's record contents and attachment paths into an attacker-controlled vehicle) plus a weak integrity effect (I:L - it creates persistent copies in the attacker's own vehicle, it does not corrupt the victim's data), with no availability impact. No EPSS score, no CISA KEV listing, and no public exploit code were provided, so this is 'no public exploit identified at time of analysis' - there is no evidence of active or automated exploitation. One data-quality conflict to flag: the CWE (CWE-639, Authorization Bypass Through User-Controlled Key) and the source-code fix (added UserCanEditVehicle checks per record) clearly identify this as broken object-level authorization / IDOR, yet the input Tag 'Authentication Bypass' mislabels it - this is an authorization defect, not an authentication bypass. Overall: a legitimate authenticated IDOR worth patching, but a low-urgency issue absent active-exploitation signals and given the niche product footprint. |
| Exploit ScenarioDerived | A registered low-privileged user on a shared/household LubeLogger instance calls the DuplicateRecordsToOtherVehicles endpoint, supplying recordIds that belong to another user's vehicle while naming a destination vehicleId they legitimately control. Because the endpoint authorized only the destination vehicles and never checked UserCanEditVehicle on each source record's VehicleId, the victim's service, fuel, tax, odometer, inspection and other records - including attachment paths - are copied into the attacker's vehicle, exposing their contents. No public exploit code was identified at time of analysis. |

Alert meAnalysisAIv1 – Sep 18, 2026
Authenticated users of LubeLogger versions prior to 1.6.8 can copy other users' vehicle maintenance records into a vehicle they control, because the DuplicateRecordsToOtherVehicles endpoint authorizes the destination vehicle but never checks edit permission on the source vehicle. This exposes the contents of service, collision, upgrade, fuel, tax, supply, note, odometer, reminder, plan, inspection and equipment records, including attachment paths, and creates persistent attacker-held copies. The flaw is rated CVSS 3.1 7.1 High (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N) and only matters on multi-user or household-shared instances; there is no confirmed active exploitation (not in CISA KEV) and no public exploit identified at time of analysis. The vendor-released patch: 1.6.8.
RemediationAI
Apply the vendor-released patch: 1.6.8, which introduces the missing UserCanEditVehicle(HouseholdPermission.Edit) check for every source record branch in DuplicateRecordsToOtherVehicles; the corresponding upstream fix is commit c8d5888ebc69e6a163e33f36200233ec845e5c57 from pull request 1395, and release notes are at https://github.com/hargata/lubelog/releases/tag/v1.6.8 with the advisory at https://github.com/hargata/lubelog/security/advisories/GHSA-3r34-mx83-q67r. If immediate upgrade is not possible, compensating controls are: run the instance in single-user mode or disable household/multi-user sharing so no second user's records exist to be copied (this removes the feature benefit but eliminates the IDOR precondition entirely), audit and remove unneeded low-privileged accounts, and restrict network reachability of the web UI to trusted networks or place it behind an authenticating reverse proxy. Note that the 1.6.8 fix also adds a root-user-only restriction to the file upload handler in FilesController, so administrators who previously relied on non-root accounts uploading files will need to re-scope those workflows. Regardless of interim controls, audit logs and existing record sets for unexpected duplicate records on attacker-controlled vehicles, since successful exploitation creates persistent copies rather than transient reads.

Technical ContextAI · show details
LubeLogger is a self-hosted ASP.NET Core web application for vehicle maintenance and fuel tracking, developed under the GitHub organization hargata (CPE cpe:2.3:a:hargata:lubelog). The defect is a classic CWE-639 authorization bypass through user-controlled key, an IDOR: the POST/action DuplicateRecordsToOtherVehicles in Controllers/VehicleController.cs accepts caller-supplied lists of source recordIds and destination vehicleIds. The code correctly verifies that the caller holds HouseholdPermission.Edit on each destination vehicle, but iterated over the fetched source records without calling _userLogic.UserCanEditVehicle(GetUserID(), existingRecord.VehicleId, HouseholdPermission.Edit). Because record lookup is keyed purely by the numeric identifier supplied by the caller, any authenticated account that can edit at least one vehicle can name arbitrary victim record identifiers and have them cloned. The commit c8d5888e adds the missing per-record source-vehicle check inside each of the eleven record-type branches, including a special case that only enforces vehicle access when existingRecord.VehicleId is not the shop-supplies default and rejects duplication when server-side shop supplies are disabled. The same pull request hardens Controllers/FilesController.cs by adding [Authorize(Roles = nameof(UserData.IsRootUser))] to the file upload handler, indicating a related privilege-boundary concern. The vulnerability requires no user interaction and no administrative role, but does require valid credentials and the existence of another user's records to enumerate.

Lifecycle Timeline
2DescriptionCVE.org
LubeLogger is a self-hosted, open-source, web-based vehicle maintenance and fuel mileage tracker. Prior to 1.6.8, an authenticated user could submit caller-controlled recordIds to the DuplicateRecordsToOtherVehicles endpoint while naming destination vehicleIds the user could edit. The endpoint authorized the destination vehicles but fetched source records in Controllers/VehicleController.cs without checking UserCanEditVehicle for each existingRecord.VehicleId. This missing source-vehicle authorization allowed service, collision, upgrade, fuel, tax, supply, note, odometer, reminder, plan, inspection, and equipment records belonging to another user to be copied into an attacker-controlled vehicle, exposing record contents and attachment paths and creating persistent copies. This issue is fixed in version 1.6.8.

Executive ViewAI
LubeLogger versions before 1.6.8 contain a high-severity vulnerability that allows any authenticated user to copy other users' vehicle maintenance records into their own vehicles, including attachments, creating persistent unauthorized copies. This flaw affects organizations or households that share a LubeLogger instance among multiple users, potentially exposing sensitive maintenance and operational data. Leadership should prioritize immediate remediation to prevent data leakage and protect user privacy.
