Temporal UI State Inconsistency in Desktop GUI Agents: Formalizing and Defending against TOCTOU Attacks on Computer-Use Agents

GUI agents that control desktop computers via screenshot-and-click loops introduce a new class of vulnerability: the observation-to-action gap mean 6.51 s on real OSWorld workloads creates a Time-Of-Check, Time-Of-Use TOCTOU window during which an unprivileged attacker can manipulate the UI state...

Timing Attack

Overview Affected versions of this package are vulnerable to Timing Attack via the TokenAuthenticator process. An attacker can determine valid usernames by measuring response time differences when submitting authentication requests with the X-AUTH-USER header. Remediation Upgrade kimai/kimai to...

Kimai: Username enumeration via timing on X-AUTH-USER

Details src/API/Authentication/TokenAuthenticator.php calls loadUserByIdentifier first and only invokes the password hasher argon2id when a user is returned. When the username does not exist, the request returns roughly 25 ms faster than when it does. The response body is the same in both cases...
