CVE-2026-109118: rdiffweb 0 to before 7.1.1

Affected technology

rdiffweb · 0 to before 7.1.1
ikus-soft

Description’s affected range: 7.1.1

Component: Not specified by the source

Attack conditions (Vendor/CNA, CVSS 3.1): Network (remote) · Low privileges required · User interaction required

What an attacker can do

An authenticated user can cause the browse, restore, history and delete operations to resolve to a path outside the repository being operated on, via a percent-encoded traversal sequence (%2e%2e) in the request path, because the containment check uses a string prefix comparison (startswith) instead of a filesystem path boundary check. Vendor/CNA’s CVSS 3.1 assessment (base score 4.6/10) rates confidentiality impact as none; integrity and availability impact as low.
