CVE-2026-40547
Status: DeferredMedium (6.4)—
SOPlanning is vulnerable to Path Traversal in backup endpoints. Authenticated remote attacker is able to exploit a vulnerable endpoint and construct payloads that allow reading and executing files previously added through the backup functionality. Critically, due to CVE-2026-40543 (Missing Authorization), any backup file can be read by any (unauthorized) user.
This issue affects SOPlanning version 1.55 and below.
