Due to the lack of server-side session destruction, an attacker can ignore the logout redirect and keep the session alive. This may allow an attacker who obtains user's password to e.g. brute force the second-factor code.\n\n\n\n\nThis issue was fixed in commit 4640889.","epss":{"date":"2026-11-04","percentile":0.28278,"score":0.00346},"exploits":[],"kev":null,"metrics":[{"score":6.3,"severity":"medium","source":"CNA: CERT-PL","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"}],"modifiedAt":1793804298794,"publishedAt":1793093721367,"references":[{"source":"CNA: CERT-PL","tags":["third-party-advisory"],"url":"https://cert.pl/en/posts/2026/10/CVE-2026-107145"},{"source":"CNA: CERT-PL","tags":["patch"],"url":"https://github.com/alexandregz/twofactor_gauthenticator/blob/master/CHANGES-2FA-SECURITY.en.md"}],"remediation":[{"kind":"fix","source":"CNA: CERT-PL","text":"The reporting source identifies this reference as a patch.
