## Summary
The Tor Project has issued Tails 7.15.1 as an emergency update following the compromise of eMudhra certificate authority intermediate certificates. The release updates Tor Browser to version 15.0.26 to fix CVE-2026-113470 and updates the Debian ca-certificates package. This prevents attackers from impersonating websites via HTTPS, a risk that could be exploited by exit nodes or ISPs.

## Security implications of the eMudhra compromise
- Updates **Tor Browser to 15.0.26** to address **CVE-2026-113470**.
- Blocks all **eMudhra** certificates within the system via the **ca-certificates Debian package**.
- Mitigates risks where an attacker (such as an exit node or ISP) could impersonate a website using compromised intermediate certificates.
- **Onion sites** remain unaffected by this specific vulnerability.

## Why it matters
Users running Tails should upgrade immediately to protect their HTTPS connections from impersonation attacks, though onion services are not at risk.
