Vulnerability details
The vulnerability allows a remote user to spoof approval decision attribution.
The vulnerability exists due to insufficient verification of data authenticity in the approval-resolution endpoints when processing a client-supplied decidedByUserId field. A remote user can send a specially crafted request with another user's identifier to spoof approval decision attribution.
For hire_agent approvals with a monthly budget, the forged identifier is also written into budget_policies audit columns. In multi-user authenticated deployments, any board member with access to the approval's company can exploit this issue.
