Prior to 1.35.5, refresh tokens are not invalidated when the user&#8217;s security_stamp is rotated by some security-sensitive operations (password change, KDF change, key rotation, email change, org admin password reset, emergency access takeover). This allows an attacker holding a previously obtained refresh token to maintain session access even after the user has taken action to secure their account. This vulnerability is fixed in 1.35.5.<\/p>\n<p>  Severity: 6.8 | MEDIUM<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-43911 Published : May 11, 2026, 11:20 p.m. | 2\u00a0hours, 37\u00a0minutes ago Description :Vaultwarden is a Bitwarden-compatible server written in Rust.
