Impact

The vulnerability allows an attacker access to one endpoint (i.e. the targeted endpoint) using the authorization requirements of a different endpoint (i.e. the donor endpoint). In some Grails framework applications using the Grails Spring Security Core (GSSC) plugin, access to the targeted endpoint will be granted based on meeting the authorization requirements of the donor endpoint, which can result in a privilege escalation attack.

Patches

The vulnerability has been patched in GSSC plugin versions 3.3.2, 4.0.5, and 5.1.1.

Workarounds

If you are unable to upgrade to a patched version of the plugin, the GSSC-CVE-2022-41923 repository contains workarounds for GSSC plugin versions 2.x through 5.x. The workaround is especially important for version 2.x, as no patch is available version 2.x of the GSSC plugin.
