Tier D because: Does not hit tech teams

The Brief
- A post on the oss-security list reports that Home Assistant stores token secrets in cleartext and that two token classes never expire.
- The post also reports that changing the password revokes none of the existing tokens, and says this was live-proven on version 2026.11.0.
- A reply in the same thread questions whether the reporter notified and coordinated with the project before publishing.
Why it matters
If the reported behaviour holds, a leaked Home Assistant token could stay valid indefinitely, even after the account password is changed.
The checklist behind the tier
Checklist · 0 of 10 yes
| No | Hits tech teams | Judgment: Home Assistant is a consumer smart-home platform, not software developers or ops teams run. |
| No | Core infrastructure | Judgment: a single smart-home application, not software nearly every team runs. |
| No | Popular tool | Judgment: popular in hobbyist smart-home circles, but not mainstream developer tech used by many teams. |
| No | Exploited in the wild | Open Source Security post reports a live-proven weakness, but no source reports observed attacks. |
| No | Public exploit | Open Source Security post describes the flaws; no source says exploit code or a PoC is published. |
| No | Remote, no login | Open Source Security post does not say the flaws are reachable without credentials. |
| No | Full takeover | Open Source Security post does not report code execution, admin takeover or account takeover. |
| No | Secrets exposed | Open Source Security post says token secrets are stored in cleartext; no source reports they were stolen. |
| No | Supply chain | Open Source Security post reports token and password weaknesses; no source reports malicious code shipped. |
