tailscale -- Insufficient validation of 4via6 subnet router destinations
Tailscale team reports: Insufficient validation of 4via6 subnet router destinations permitted access to host-scoped addresses, including cloud metadata and loopback services. TS-2026-11
Affected versions
- tailscale < 1.102.3
By system
0 still vulnerable, 1 fixed. Where VuXML applies (FreeBSD, DragonFly, FreeBSD's derivatives) a port is vulnerable while its version is in a range; pkgsrc says itself whether it lists a CVE of this advisory; OpenBSD and MidnightBSD keep no list this site reads, so their row is only an estimate: FreeBSD's ranges applied to upstream's version.
| System | Port | Version | State | Fixed |
|---|---|---|---|---|
| FreeBSD | security/tailscale | 1.104.2 | fixed | |
| OpenBSD | net/tailscale | 1.104.1 | out of range, by version | |
| NetBSD | net/tailscale | 1.102.4 | not listed | |
| MidnightBSD | security/tailscale | 1.104.2 | out of range, by version |
