FOSSBilling: Low-privileged staff can read and modify configuration of deactivated extensions

Sources read

Source agreement

Tam uyum

Evidence confidence

%63

Short explanation

In FOSSBilling versions, low-privileged staff accounts can read and modify configurations of deactivated extensions because hasManagePermission fails open for inactive non-core modules. This vulnerability remains as a residual path after an earlier authorization fix for CVE-2026-62962.

Why does it matter?

Unauthorized accounts can access decrypted retained extension secrets and overwrite stored extension configurations.

Show the technical text from the sources

FOSSBilling is an open source billing and client-management platform. From 0.8.4 until 0.8.6, hasManagePermission fails open for inactive non-core modules because its early return on !isExtensionActive skips the module-access and manage_settings checks. A low-privileged staff account with module-level extension access targets a deactivated non-core module through extension/config_get or extension/config_save. The account can call api/admin/extension/config_get or api/admin/extension/config_save for a deactivated non-core module to read decrypted retained extension secrets and overwrite stored extension configuration. The getConfig function returns the decrypted stored configuration despite the module's inactive state. This residual path remained after the earlier CVE-2026-62962 authorization fix. This issue is fixed in version 0.8.6.

Confirm the affected product and version against the source evidence above.

Restrict access to internet-facing services and apply network segmentation.

Until a patch is confirmed, follow the vendor advisory; do not read an unknown status as “no patch”.

Monitor server logs and network endpoints for signs of anomalous execution.
