# CVE-2026-129110: sysPass 3.0.1 through 3.2.11 Unauthenticated Reinstallation RCE via install/install

Status: published. Published: 2026-11-13. Updated: 2026-11-13.

sysPass 3.0.1 through 3.2.11 contains an authentication bypass vulnerability that allows unauthenticated attackers to reinstall an already-installed instance by POSTing to the install/install handler, which never checks isInstalled(). Attackers can overwrite config.xml, point the application at an attacker-controlled database, create an administrator account, and plant serialized PublicLink gadget chains triggered via account/viewLink to execute commands.
