{"id":"CVE-2024-7053","details":"A vulnerability in open-webui/open-webui version 0.3.8 allows an attacker with a user-level account to perform a session fixation attack. The session cookie for all users is set with the default `SameSite=Lax` and does not have the `Secure` flag enabled, allowing the session cookie to be sent over HTTP to a cross-origin domain. An attacker can exploit this by embedding a malicious markdown image in a chat, which, when viewed by an administrator, sends the admin's session cookie to the attacker's server. This can lead to a stealthy administrator account takeover, potentially resulting in remote code execution (RCE) due to the elevated privileges of administrator accounts.","aliases":["GHSA-43g4-487m-5q6m"],"modified":"2026-03-13T07:58:01.578791Z","published":"2025-03-20T10:15:36.217Z","references":[{"type":"EVIDENCE","url":"https://huntr.com/bounties/947f8191-0abf-4adf-b7c4-d4c19683aba2"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/open-webui/open-webui","events":[{"introduced":"0"},{"last_affected":"9bcd4ce5c0a01af68c0d2aa44554a68bb741c61b"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"0.3.8"}]}}],"versions":["v0.1.102","v0.1.103","v0.1.104","v0.1.105","v0.1.106","v0.1.107","v0.1.108","v0.1.109","v0.1.110","v0.1.111","v0.1.112","v0.1.113","v0.1.114","v0.1.115","v0.1.116","v0.1.117","v0.1.118","v0.1.119","v0.1.120","v0.1.121","v0.1.122","v0.1.123","v0.1.124","v0.1.125","v0.2.0","v0.2.1","v0.2.2","v0.2.3","v0.2.4","v0.2.5","v0.3.0","v0.3.1","v0.3.2","v0.3.3","v0.3.4","v0.3.5","v0.3.6","v0.3.7","v0.3.8"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-7053.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H"}]}
