Security Research Vulnerabilities I have reported to the Apache Software Foundation, disclosed through the ASF security process. 46 CVEs across 15 projects , 2023 to 2026. Where a public reproducer exists it is linked. Each one is a minimal, self-contained project that demonstrates the issue and...

Vikunja: Task relation deletion does not check read access to the other task, allowing cross-project relation removal

Summary Deleting a task relation only requires write access on the base task. Unlike relation creation, it does not verify that the caller can read the other task. A user with write access to one project can therefore delete relations whose other end lives in a project they have no access to. Sin...

CVE-2026-97147

In OpenStack Mistral through 23.0.0, several of the v2 API write paths resolve the target object with a query that can return another project's resource, then write to it. An authenticated project member can use this to rewrite and un-publish another project's public action definitions and...

CVE-2026-66082

Apache DolphinScheduler versions before 3.4.3 are vulnerable to an authorization bypass (CWE-863) that allows authenticated users to perform unauthorized operations on workflow schedules, definitions, and task instances in other projects. The root cause is that affected endpoints verify permissio...

CVE-2026-66082 Apache DolphinScheduler: Cross-project authorization bypasses in DolphinScheduler API (schedule / workflow）

An authorization bypass vulnerability in Apache DolphinScheduler allows authenticated users to perform unauthorized operations on workflow schedules, workflow definitions, and task instances in other projects. The affected endpoints check permissions against the supplied projectCode but fail to...

GHSA-4HMC-CFM3-W43C Langflow has Authenticated Cross-Project File Disclosure via Unscoped MCP Resource Handlers

Summary Langflow's project-scoped MCP transport authenticates the caller for the projectid in the connection URL, but the subsequent resources/read operation does not authorize the resource URI being requested. An authenticated user can connect to their own project-scoped MCP endpoint and supply ...

CVE-2026-105699 Langflow: Authenticated Cross-Project File Disclosure via Unscoped MCP Resource Handlers

Langflow is a tool for building and deploying AI-powered agents and workflows. From 1.6.8 until 1.9.1, Langflow authenticated access to the project identifier in a project-scoped MCP connection but did not authorize the resource URI supplied to resources/read. readresource forwarded the...

EUVD-2026-92489

Plane is an open-source project management tool. Prior to 1.4.0, BulkDeleteIssuesEndpoint and SubIssuesEndpoint in apps/api/plane/app/views/issue/ accept body- or URL-supplied issue IDs and operate on them without checking that the IDs belong to the caller's workspace and project. The permission...
