Description
Midday allows any member of a team to delete it. The delete procedure in apps/api/src/trpc/routers/team.ts authorises the caller with the team-access helper, which returns true for every row in the team-membership table irrespective of the role it records, and the data-layer function it calls re-checks the same helper and nothing else. The neighbouring procedures that remove or update a member in the same router each resolve the caller's role and refuse the request unless it is owner, so the check exists in the file and is not applied to deletion. Member is the role an invited user receives, so any invitee can remove the team and every record scoped to it, and the deletion enqueues the cleanup job with the stored bank-connection tokens, which the job then uses against the connected providers. The update procedure in the same router carries no role check either.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-81035 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-81035 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-81035. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
