This medium-severity CVE scores 6.4 under NVD CVSS v3. EPSS exploit probability: 0.4%, top 62% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
