 .
   * OSSA-2026-044: Four authorization and privilege vulnerabilities in Mistral,
     with the details as per below (Closes: #1150346).
   * CVE-2026-97147: several of Mistral's v2 API write paths resolve the target
     object with a query that can return another project's resource, then write
     to it (CVE-2026-97147). An authenticated project member can use this to
     rewrite and un-publish another project's public action definitions and
     environments. A project administrator can create a workbook whose embedded
     ad-hoc action or workflow name collides with a resource of another project,
     which moves that resource into the caller's project and causes the original
     owner's subsequent updates of it to fail with server errors. All
     deployments exposing the Mistral API are affected. Applied upstream
     patches: "Fix create-or-update of definitions hijacking other projects'
     rows", "Enforce access control when updating action definitions", "Enforce
     access control when updating workbooks and environments", "Resolve
     own-project object when updating code sources / dynamic actions", "Resolve
     own-project cron trigger in create_or_update_cron_trigger":

   * CVE-2026-93861: Mistral's workflow membership API lets a project that has
     accepted a share of another project's private workflow create a further
     membership naming a third project (CVE-2026-93861). The new membership row
     is created with its project_id defaulted to the accepting project rather
     than the original workflow owner, so the owner can neither see nor delete
     it. The third project can accept this membership it was never actually
     granted by the owner, then read and execute the owner's private workflow;
     only the accepting (not the owning) project can later revoke that access.
     Applied upstream patch: "Only allow the owner of a resource to share it":
     - CVE-2026-93861_Only_allow_the_owner_of_a_resource_to_share_it.patch
   * CVE-2026-93858: Mistral's ssh_proxied action provider (CVE-2026-93858). By
     supplying a specially-crafted action payload, an unprivileged authenticated
     user may override paramiko's proxy_command resulting in execution of
     arbitrary code on the executor host operating system. Only Mistral
     deployments allowing the std.ssh_proxied action provider (the default) are
     affected. Applied upstream patch: "Fix RCE via std.ssh_proxied
     proxy_command":
     - CVE-2026-93858_Fix_RCE_via_std.ssh_proxied_proxy_command.patch
   * CVE-2026-93860: vulnerability in Mistral's maintenance API method. By
     calling the maintenance API method, an unprivileged authenticated user may
     pause processing for creation of new objects for all tenant projects
     resulting in a temporary denial of service. All Mistral deployments are
     affected. Applied upstream patch: "Restrict the maintenance endpoint to
     admins":
     - CVE-2026-93860_Restrict_the_maintenance_endpoint_to_admins.patch
