What is CVE-2026-53454?
CVE-2026-53454 is a medium-severity vulnerability in ha-china blueprint-studio, published on 18 Aug 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
Blueprint Studio is a VS Code-like file editor for Home Assistant configuration files. Prior to 2.5.2, Blueprint Studio configured Git's credential.helper store when saving Git credentials, causing Git credential-store to persist usernames and access tokens in plaintext in the .git-credentials file for the user running Home Assistant. Tokens could remain outside Blueprint Studio's intended Home Assistant storage and be read by other users or processes with access to the same filesystem context. The persistent helper configuration also affected later Git operations beyond the immediate Blueprint Studio action. This issue is fixed in version 2.5.2.
Weakness: CWE-522
