Upgrade mautic/core to 4.4.17Upgrade mautic/core to 5.2.8Upgrade mautic/core to 6.0.5Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for mautic/coreHow to Check if You Are Affected
To determine whether your application is affected by CVE-2025-9824, inspect your project dependencies for Mautic/core:
inspect dependencies for mautic/coreAnalyze the terminal output to locate any version of Mautic/core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.4.17), your application is affected.
Note: Verify declared build manifests and deployed runtime container environments.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-204: Observable Response Discrepancy, where the product provides different responses to incoming requests in a way that reveals internal state information to an unauthorized actor outside of the intended control sphere. In Mautic/core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Impact\nThe attacker can validate if a user exists by checking the time login returns. This timing difference can be used to enumerate valid usernames, after which an attacker could attempt brute force attacks.\n\n### Patches\nThis vulnerability has been patched, implementing a timing-safe form login authenticator that ensures consistent response times regardless of whether a user exists or not.\n\n### Technical Details\nThe vulnerability was caused by different response times when:\n- A valid username was provided (password hashing occurred)\n- An invalid username was provided (no password hashing occurred)\n\nThe fix introduces a `TimingSafeFormLoginAuthenticator` that performs a dummy password hash verification even for non-existent users, ensuring consistent timing.\n\n### Workarounds\nNo workarounds are available. Users should upgrade to the patched version.\n\n### References\n- https://owasp.org/www-project-web-security-testing-guide/latest/4-Web_Application_Security_Testing/03-Identity_Management_Testing/04-Testing_for_Account_Enumeration_and_Guessable_User_Account\n- https://github.com/mautic/mautic-security/pull/146",
