Tauri framework v2 missing updater signature version number validation can be exploited into forced downgrade
CVSS 3.1 5.9 MEDIUMCheck source for fixed versionsKEV status unknown
cve-program · CVE-2026-95625
PublishedThe Tauri updater plugin verifies update binaries using minisign signatures, but the signature covers only the raw binary bytes. The update manifest -- which contains the version number, download URL, and signature -- is fetched over TLS but is never itself signed or authenticated. Because the only anti-rollback check compares the manifest's version field against the current version, and that field is unsigned, an attacker who can serve a crafted manifest can force installation of any older signed release without possessing the developer's private key.

Exploitation and risk
Source statusCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
Which CVEs have scores here?
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.
Risk history
Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.
When does an EPSS score appear as a change?
A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.
Advisory history
1 saved versionsSee how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.
How advisory history works
Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
