Summary
Fix CVE(s): CVE-2026-80230, CVE-2026-82209
Details
  • SECURITY UPDATE: public key pinning bypassed when no server certificate
    • debian/patches/CVE-2026-80230.patch: in lib/vtls/openssl.c, treat a missing server certificate as acceptable only when no pinned public key is configured, so pinning is still enforced with peer and host verification disabled.
    • CVE-2026-80230
  • SECURITY UPDATE: cookie for an exact PSL domain kept wildcard scope
    • debian/patches/CVE-2026-82209.patch: in lib/cookie.c, clear the tailmatch flag when a cookie's Domain attribute is itself a public suffix, so it becomes host-only instead of being sent to sibling subdomains.
