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.

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7981-1 advisory.

    It was discovered that wlc did not correctly handle SSL verification. An attacker could possibly use this     issue to access sensitive resources. (CVE-2026-22250)

    It was discovered that wlc did not correctly handle API keys. An attacker could possibly use this issue to     leak API keys to a malicious server. (CVE-2026-22251)
