Title
Penpot: Pre-authenticated account takeover via team-invitation token + prepare-register-profile
Summary
Penpot is an open-source design tool for design and code collaboration. Prior to 2.14.5, Penpot exposed teams_invitations.clj invitation tokens from create-team-invitations, embedded an existing profile id in auth.clj prepare-register-profile, and had auth.clj register-profile issue a session based on the invitation email match without password verification, allowing a registered user to take over any non-blocked profile. This issue is fixed in version 2.14.5.

Title
Kavita: IDOR in /api/Download/*
Summary
Kavita is a cross platform reading server. Prior to 0.9.0, the download, size-check, and chapter metadata endpoints do not enforce library-level authorization. A low-privileged user who knows or guesses a chapterId, volumeId, or seriesId belonging to a library they are not assigned to can download the full file contents, query file sizes, and read metadata for that content. This affects /api/Download/volume-size, /api/Download/chapter-size, /api/Download/series-size, /api/Download/volume, /api/Download/chapter, /api/Download/series, and /api/Chapter. This vulnerability is fixed in 0.9.0.

Title
OpenProject: Relations API Filter Bypasses Visibility Scope, Leaking Cross-Project Work Package Subjects
Summary
OpenProject is open-source, web-based project management software. Prior to 17.4.0, the GET /api/v3/relations endpoint allows any authenticated user to retrieve relations — and the subject (title) of work packages they have no permission to view — by supplying an arbitrary work package ID in the involved, fromId, or toId filter. This bypasses the Relation.visible scope due to a flawed performance optimization in RelationQuery. This vulnerability is fixed in 17.4.0.

CVE-2026-44732 (GCVE-0-2026-44732)

Vulnerability from cvelistv5 – Published: 2026-06-26 19:39 – Updated: 2026-06-29 12:10

Title
OpenProject: IDOR on OpenProject through /api/v3/documents/{id} via PATCH parameter "project_id" leads to Unauthorized Modification of Resources
Summary
OpenProject is open-source, web-based project management software. Prior to 17.3.2 and 17.4.0, OpenProject exposes a document update endpoint used to modify existing documents. The target document is loaded with visibility checks and then updated. During update, attacker-controlled attributes are applied to the persisted record before authorization is enforced. As a result, a user without :manage_documents in the source project can move and modify foreign project documents by setting project_id in a single PATCH request. This vulnerability is fixed in 17.3.2 and 17.4.0.

Title
OpenProject: Improper Access Control on OpenProject through /projects/[projectName]/meetings via "invited_user_id" in GET parameter "filters" leads to user names disclosure
Summary
OpenProject is open-source, web-based project management software. Prior to 17.3.2 and 17.4.0, the web application's meetings filter feature leaks whether a given user ID corresponds to a valid account and discloses the user's full name, allowing an attacker to enumerate all existing user accounts by probing user IDs and observing differences in the server response. This vulnerability is fixed in 17.3.2 and 17.4.0.

CVE-2026-44718 (GCVE-0-2026-44718)

Title
Mathesar: Missing collaborator checks allowed access to saved explorations in other databases
Summary
Mathesar is a web application that makes working with PostgreSQL databases both simple and powerful. From 0.2.0 to before 0.10.0, explorations.get, explorations.replace, and explorations.delete operate on an exploration_id without verifying that the requesting user was a collaborator on the exploration’s database. An authenticated user on the same Mathesar installation who knew or guessed an exploration ID could read, replace, or delete a saved exploration belonging to a database where they were not a collaborator. This affected Mathesar-managed saved exploration definitions, including names, descriptions, selected columns, display metadata, filters, sorting, and transformations. This vulnerability is fixed in 0.10.0.

An authenticated user on the same Mathesar installation who knew or guessed an exploration ID could read, replace, or delete a saved exploration belonging to a database where they were not a collaborator.

CVE-2026-44692 (GCVE-0-2026-44692)

Title
Authenticated Sharp users can download unrelated Laravel Storage objects through the generic download endpoint
Summary
Sharp is a content management framework built for Laravel as a package. Prior to version 9.22.0, Sharp exposes a generic download endpoint that authorizes access only to the supplied Sharp entity instance, but then reads the target storage disk and path from request parameters. Because the requested storage object is not bound to the authorized entity instance, an authenticated Sharp user who can view one valid record may use that record as an authorization anchor to download unrelated disk-relative objects from configured Laravel Storage disks. The confirmed impact is authenticated disclosure of unrelated objects from configured Laravel Storage disks. This issue does not imply arbitrary host filesystem access outside configured Laravel Storage disk roots. This issue has been patched in version 9.22.0.

Title
Tuist: IDOR in preview deletion API allows cross-tenant deletion of any preview by UUID
Summary
Tuist is a virtual platform team for Swift app devs. In 1.180.8 and earlier, the DELETE /api/projects/{account_handle}/{project_handle}/previews/{preview_id} endpoint loads the preview by its UUID without verifying that the preview belongs to the project resolved from the URL path. The route's project-level authorization plug (AuthorizationPlug, :preview) authorizes the caller against the project encoded in account_handle/project_handle — which the attacker controls — and then the action deletes whichever preview's UUID is supplied. The check therefore guards the wrong project.

CVE-2026-44570 (GCVE-0-2026-44570)

Title
Open WebUI: Inconsistent authorization controls within memories API
Summary
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.6.19, authorization controls surrounding the memories API were inconsistent, resulting in the ability of a standard user to delete, restore, and view the contents of other users' memories. Using a newly created non-admin user with no existing memories, it is possible to view existing memories via POST /api/v1/memories/query. Similarly, even if a non-admin user cannot modify another user's memory data via POST /api/v1/memories/{memory_id}/update, the endpoint's response improperly leaks the content of that memory if a valid memory_id is known. The DELETE /api/v1/memories/{memory_id} can also be used by any user to delete an existing memory. Deleted memories can then be restored by calling the POST /api/v1/memories/{memory_id}/update endpoint again. This vulnerability is fixed in 0.6.19.

Using a newly created non-admin user with no existing memories, it is possible to view existing memories via POST /api/v1/memories/query. Similarly, even if a non-admin user cannot modify another user\u0027s memory data via POST /api/v1/memories/{memory_id}/update, the endpoint\u0027s response improperly leaks the content of that memory if a valid memory_id is known. The DELETE /api/v1/memories/{memory_id} can also be used by any user to delete an existing memory. Deleted memories can then be restored by calling the POST /api/v1/memories/{memory_id}/update endpoint again. This vulnerability is fixed in 0.6.19."

CVE-2026-44544 (GCVE-0-2026-44544)

Title
gittuf: Policy can be rolled back to prior valid version
Summary
gittuf is a platform-agnostic Git security system. Prior to 0.14.0, an attacker with push access to gittuf's Reference State Log (RSL) can roll back the current policy to any previous policy trusted by the current set of root keys. gittuf determines the policy to load by inspecting the RSL. Except for the very first policy (which is automatically trusted given gittuf's TOFU model, or verified against manually specified keys), whenever an RSL entry that points to a new policy is encountered, gittuf validates that this policy is trusted. This is done by checking that the new policy’s root metadata is signed by the required threshold of the current policy's root keys. Because of this, an attacker with push access to the RSL may create a new entry that references an old policy (that is trusted by the most recent policy's set of root keys), thereby rolling back gittuf's policy to the attacker's chosen state. This vulnerability is fixed in 0.14.0.

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.
