Title
Kimai: Improper Authorization in Kimai Activity Creation with Preset Project Allows Creation Under Unauthorized Projects
Summary
Kimai is an open-source time tracking application. Prior to 2.57.0, GET or POST requests to /en/admin/activity/create/{project} and /en/admin/project/create/{customer} require only the generic create_activity or create_project capability and do not verify edit access to the supplied Project or Customer object. A user who knows a valid project.id or customer identifier can use the preset-parent creation logic in src/Controller/ActivityController.php or src/Controller/ProjectController.php to persist a new child business object under an unauthorized parent, polluting project or customer configuration and influencing later time-entry, rate, reporting, and billing behavior. This issue is fixed in version 2.57.0.

Title
Kimai: Timesheet PATCH/POST allows assigning to project outside user's team via query_builder OR-bypass
Summary
Kimai is an open-source time tracking application. Prior to 2.57.0, PATCH /api/timesheets/{id} and POST /api/timesheets accept a user-controlled project identifier through TimesheetApiEditForm and FormTrait, and ProjectRepository::getQueryBuilderForFormType() places that identifier in an unconditional OR branch that bypasses the team access criteria. Any authenticated user with edit_own_timesheet can therefore assign an owned timesheet to a project outside the user's teams, persist unauthorized project attribution, and retrieve project and customer metadata through GET /api/timesheets/{id}?full=true. TimesheetTeamAccessValidator now checks changed project and activity associations against current team access. This issue is fixed in version 2.57.0.

Gogs: LFS dedupe path leaks private repo content across tenants
Summary
Gogs is an open source self-hosted Git service. Prior to 0.14.3, Git LFS storage is content-addressed by OID alone (<LFS-root>/<oid[0]>/<oid[1]>/<oid>) but per-repo authorization lives in the lfs_object table keyed (repo_id, oid). serveUpload skips re-uploading when the OID file already exists on disk and inserts a new (repo_id, oid) row pointing at it without verifying the request body hashes to the OID being claimed. Any user with write access to one repo can bind their repo to an OID owned by a private repo and download the original bytes via their own download endpoint. This vulnerability is fixed in 0.14.3.

Title
Gogs: Missing Authorization in Attachment Download
Summary
Gogs is an open source self-hosted Git service. Prior to 0.14.3, GET /attachments/:uuid returns the raw attachment file without verifying whether the requester has view permission for the associated Issue/Comment/Release or the repository.
In a test environment with REQUIRE_SIGNIN_VIEW = false, we confirmed that an unauthenticated user can download attachments belonging to a private repository. This vulnerability is fixed in 0.14.3.

Title
OpenProject: IDOR through /projects/<A>/settings/project_storages/<A_ps_id> via PATCH parameter "storages_project_storage[project_folder_id]" leads to Access to Unauthorized Resources
Summary
OpenProject is open-source, web-based project management software. Prior to 17.3.3 and 17.4.1, there is an IDOR through /projects/<A>/settings/project_storages/<A_ps_id> via PATCH parameter "storages_project_storage[project_folder_id]" leads to Access to Unauthorized Resources. A project-admin in one project can hijack the managed Nextcloud or OneDrive folder of another project on the same storage by writing the victim project's project_folder_id into the attacker's Storages::ProjectStorage row. The next managed-folder sync overwrites the ACL on the referenced folder with the attacker project's user list. This vulnerability is fixed in 17.3.3 and 17.4.1.

Title
OpenProject: Cross-project authorization bypass allows deleting public Calendar and Team Planner queries from unauthorized projects
Summary
OpenProject is open-source, web-based project management software. Prior to 17.3.3 and 17.4.1, a cross-project IDOR / authorization context confusion in the Calendar and Team Planner modules allows a user with management permissions in one project to delete public Calendar or Team Planner Queries from another project where they do not have the corresponding management permissions. Both modules authorize the request against the project identified by :project_id in the URL, but the actual Query object is loaded later by :id from Query.visible(current_user) without verifying that the loaded Query belongs to the authorized project. As a result, an attacker can use permissions from Project A to delete shared/public Calendar or Team Planner views from Project B, causing integrity impact and limited availability impact for users relying on those shared views. This vulnerability is fixed in 17.3.3 and 17.4.1.

Title
GoCD before 26.1.0 is vulnerable to authorization bypass via job status API
Summary
GoCD is a continuous deliver server. Prior to 26.1.0, the internal GoCD UI /jobStatus.json API does not validate that a requested server-assigned job ID belongs to the pipeline and stage named in the request. An authenticated user can guess job IDs and retrieve status for jobs in pipelines the user cannot otherwise view, including job names, state, progress timestamps, assigned agent IP addresses and UUIDs, and associated stages and pipelines. The response does not expose console output, artifacts, commands, variables, or configuration. This issue is fixed in version 26.1.0.

Title
DataEase: Token with Overly Broad Privileges in Share Mode: Access to Unshared Datasets
Summary
DataEase is an open source data visualization and analysis tool. Prior to 2.10.24, a share mode chart data interface only validates that sceneId matches the resourceId in the link token and fails to validate whether tableId and field IDs in the request body belong to the shared resource, allowing an attacker with a valid share link token to replace dataset identifiers and retrieve unauthorized data through POST /de2api/chartData/getData. This issue is fixed in version 2.10.24.

Title
Craft CMS: Unauthorized Deletion of Source Assets During File Replacement
Summary
Craft CMS is a content management system (CMS). Versions 5.0.0-RC1 through 5.9.20, and 4.0.0-RC1 through 4.17.13 contain an authorization issue in the AssetsController::actionReplaceFile that can delete a source asset without source delete permission by supplying both assetId and sourceAssetId. AssetsController::actionReplaceFile() supports replacing a target asset file using another existing asset as the source. The action loads: assetId -> $assetToReplace and sourceAssetId -> $sourceAsset, then enforces replace permissions using ($assetToReplace ?: $sourceAsset). When both IDs are provided, this expression resolves to the target asset so no permission check is performed against the source asset volume. When both assets are present, Craft copies the source file into the target and then deletes the source asset. There is no deletion check for for the source asset. An authenticated user who can replace files in one volume can delete assets in another volume where they do not have delete permission, as long as they can obtain a sourceAssetId, leading to broken content references and data loss. This issue has been fixed in versions 4.17.14 and 5.9.21.

Mitigation
Architecture and Design
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Mitigation
Architecture and Design
Implementation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation
Architecture and Design
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
