CVE-2025-14551Network attack vector

Credential disclosure via unredacted installer crash logs

Published Apr 9, 2026 · Updated Apr 9, 2026

Information disclosure in Subiquity 24.04.4, 25.04 and 25.10 for Ubuntu allows attackers to obtain credentials from submitted crash logs. The installer logs identity API responses and network configuration details without consistently suppressing or redacting sensitive values before those logs are attached to a crash report. An installation must fail and a user must submit the report to Launchpad; exposed data includes plaintext Wi-Fi passwords and identity data.
