What is CVE-2024-37882?

A vulnerability in the Nextcloud Server allows users who have been granted read&share permissions on shared items to reshare those items, potentially with additional privileges. This unauthorized escalation of permissions can lead to unintended data exposure and compromise the intended access controls. To address this vulnerability, it is essential that users upgrade to the secure versions: Nextcloud Server 26.0.13, 27.1.8, or 28.0.4, as well as the respective versions for the Nextcloud Enterprise Server. Failing to do so may expose sensitive data to unauthorized users.

Affected Version(s)

security-advisories >= 26.0.0, < 26.0.13 < 26.0.0, 26.0.13

security-advisories >= 27.0.0, < 27.1.8 < 27.0.0, 27.1.8

security-advisories >= 28.0.0, < 28.0.4 < 28.0.0, 28.0.4
