What it is: CVE-2026-24667 is a medium-severity authentication bypass vulnerability in gunet openeclass, published on 3 Feb 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-24667 in the wild and no public exploit code.
