description

ph7builder versions before 18.5.0 are affected by a path traversal flaw in the picture module's file-deletion action. An authenticated member may delete files outside the intended photo scope, potentially causing content loss or denial of service. Exploitation requires an authenticated account able to access the affected picture function.

mitigation

Upgrade ph7builder to version 18.5.0 or later. Until upgraded, restrict access to untrusted member accounts and the affected picture-deletion functionality where feasible.

fixed in 18.5.0
