{“lastseen”:””,”description”:”ImpactThe 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\\nPatchesThis 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\\nTechnical DetailsThe vulnerability was caused by different response times when:\\n\\n * A valid username was provided (password hashing occurred)\\n * An invalid username was provided (no password hashing occurred)\\n\\n\\nThe fix introduces a TimingSafeFormLoginAuthenticator\u00a0that performs a dummy password hash verification even for non-existent users, ensuring consistent timing.\\n\\nWorkaroundsNo workarounds are available. Users should upgrade to the patched version.\\n\\nReferences * 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”,”published”:”2025-09-03T14:25:06.796Z”,”modified”:”2025-09-03T14:46:19.282Z”,”type”:”cve”,”title”:”User Enumeration via Response Timing”,”source”:”Mautic”,”references”:”https:\/\/github.com\/mautic\/mautic\/security\/advisories\/GHSA-3ggv-qwcp-j6xg”,”id”:”CVE-2025-9824″,”bulletinFamily”:””,”cwe”:[“CWE-204″],”cvelist”:null,”sourceData”:”Mautic Mautic \\u003e= 4.4.0\\nMautic Mautic \\u003e= 5.0.0-alpha\\nMautic Mautic \\u003e= 6.0.0-alpha”,”sourceHref”:””,”cvss”:{“score”:5.9,”severity”:”MEDIUM”,”vector”:”CVSS:3.1\/AV:N\/AC:H\/PR:N\/UI:N\/S:U\/C:N\/I:N\/A:H”,”version”:”3.1″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”Mautic”,”version”:”\\u003e= 4.4.0″,”vendor”:”Mautic”,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
