Not reviewed by a person. > Versions 7.5.0 up to but not including 7.5.29 of ezsystems/ezpublish-kernel are affected by a login timing weakness. The existing randomized delay that hides whether an account exists did not work reliably in some situations, so an attacker who can send login attempts could tell whether a given account exists without knowing its password. Upgrade to version 7.5.29. The fix adds the security.yml setting ibexa.security.authentication.constant_auth_time, and if the log warns that the constant time was exceeded, increase that setting.

We don’t reproduce full advisory descriptions, which can contain exploit code. ## Check whether this affects you A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet. - With the agentprime MCP server (), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: - In a browser: reads your lockfile in the browser, never uploading it. - Whether it touches your code, with file and line: the Claude Code plugin, - As JSON: , or `POST https://api.agentprime.io/v1/match` with your packages () --- The web page: .
