CVE-2026-22251: Weblate Wlc

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

wlc is a Weblate command-line client using Weblate's REST API. Prior to 1.17.0, wlc supported providing unscoped API keys in the setting. This practice was discouraged for years, but the code was never removed. This might cause the API key to be leaked to different servers.

Affected products

• Weblate Wlc: before 1.17.0 (fixed in 1.17.0)
