CVE-2025-64408 | Apache Causeway: Java deserialization vulnerability to authenticated attackers

Apache Causeway faces Java deserialization vulnerabilities that allow remote code execution (RCE) through user-controllable URL parameters. These vulnerabilities affect all applications using Causeway's ViewModel functionality and can be exploited by authenticated attackers to execute arbitrary code with application privileges.  This issue affects all current versions. Users are recommended to upgrade to version 3.5.0, which fixes the issue.

6.3 3.1 MEDIUM
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
