Description

Fix
A fix is available for CVE-2023-33264; check the affected-versions list above or the advisory for the patched release of com.hazelcast:hazelcast, then make sure no transitive dependency still pins the vulnerable range.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
