Because refresh tokens have a significantly longer lifetime (default one year), an authenticated client could use a refresh token in place of an access token to maintain long-term access without token rotation. Additionally, old access tokens remained valid after refresh, enabling concurrent or extended use beyond intended session boundaries. This vulnerability could allow prolonged unauthorized access if a token is disclosed.<\/p>\n<p>Severity: 6.2 | 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-2026-1842 Published : Feb. 20, 2026, 4:23 p.m. | 39\u00a0minutes ago Description : HyperCloud versions 2.3.5 through 2.6.8 improperly allowed refresh tokens to be used directly for resource access and failed to invalidate previously issued access tokens when a refresh token was used.
