This is due to improper user check error handling in the two-factor REST API actions with the 'check_login_and_get_user' function. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, when the \"Two-Factor Authentication\" setting is enabled (disabled by default).","published":"2024-11-15T04:15:04.000Z","lastModified":"2026-06-17T06:56:43.000Z","status":"Modified","sourceIdentifier":"security@wordfence.com","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-288","CWE-306"],"affected":["really-simple-plugins/really simple security"],"epss":{"score":0.82218,"percentile":0.99657,"date":"2026-11-03","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2025-04-15","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":52207,"kind":"exploit","title":"Really Simple Security 9.1.1.1 - Authentication Bypass","url":"https://www.exploit-db.com/exploits/52207","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/php/webapps/52207.py","file":"exploits/php/webapps/52207.py","published":"2025-04-15","added":"2025-04-15","updated":"2025-04-15","author":"Antonio Francesco Sardella","type":"webapps","platform":"php","port":null,"verified":false,"codes":["CVE-2024-10924"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 82.2%, higher than 100% of all known CVEs.
