Prior to 1.11.38 and 2.0.0-RC.3, the default password reset mechanism generates tokens using sha1($email) with no random component, no expiration, and no rate limiting. An attacker who knows a user's email can compute the reset token and change the victim's password without authentication. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3.","published":"2026-04-10T19:16:24.000Z","lastModified":"2026-10-26T21:10:00.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.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-640"],"affected":["chamilo/chamilo lms"],"epss":{"score":0.00426,"percentile":0.3672,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.43%).
