High CVSS 7.1
CVE-2026-48099
NVD analysis in progress
WsgiDAV is a generic and extendable WebDAV server based on WSGI. WsgiDAV 4.3.3 and prior can allow a WebDAV request path containing an encoded parent-directory segment to escape the configured filesystem share root in a specific path layout. The issue is fixed with version 4.3.4.
What this means
- Exposure
- Exploitable remotely over the network, with an ordinary user account and with no action from the victim. The attack does require particular conditions, which makes it less systematic.
- Impact
- An attacker can read sensitive data, modify or destroy data and degrade the service.
- Weakness
- An attacker-supplied file path is not confined, letting them read or write outside the intended folder.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
