Versions prior to 0.8.0 allow a low-privileged staff account to grant arbitrary module permissions to itself through the admin API, resulting in persistent privilege escalation. A staff user that only has `staff.create_and_edit_staff` can call `\/api\/admin\/staff\/permissions_update` targeting their own account and write any permission structure, bypassing the intended role-based access control boundary. Version 0.8.0 patches the issue. Some workarounds are available. Restrict the `staff.create_and_edit_staff` permission to only highly trusted staff members and\/or use a reverse proxy or WAF to restrict access to `\/api\/admin\/staff\/permissions_update` to specific trusted roles.<\/p>\n<p>  Severity: 8.5 | HIGH<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-53645 Published : July 6, 2026, 11:16 p.m. | 31\u00a0minutes ago Description :FOSSBilling is a free, open-source billing and client management system.
