{"id":"CVE-2021-41180","details":"Nextcloud talk is a self hosting messaging service. In versions prior 12.1.2 an attacker is able to control the link of a geolocation preview in the Nextcloud Talk application due to a lack of validation on the link. This could result in an open-redirect, but required user interaction. This only affected users of the Android Talk client. It is recommended that the Nextcloud Talk App is upgraded to 12.1.2. There are no known workarounds.","aliases":["GHSA-4fxr-mrw2-cq92"],"modified":"2026-08-07T19:48:39.505680Z","published":"2022-03-08T18:15:07.737Z","references":[{"type":"REPORT","url":"https://github.com/nextcloud/security-advisories/security/advisories/GHSA-4fxr-mrw2-cq92"},{"type":"FIX","url":"https://github.com/nextcloud/spreed/pull/6239"},{"type":"FIX","url":"https://hackerone.com/reports/1337178"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nextcloud/spreed","events":[{"introduced":"0"},{"fixed":"928b9efbb685db7b383c201851a1efaf4c5ef7a9"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:nextcloud:talk:*:*:*:*:*:android:*:*","extracted_events":[{"introduced":"0"},{"fixed":"12.1.2"}]}}],"versions":["v12.0.1","v12.0.0","v12.0.0-rc.1","v12.0.0-alpha.4","v12.0.0-alpha.3","v12.0.0-alpha.2","v12.0.0-alpha.1","v11.0.0-alpha.4","v11.0.0-alpha.3","v11.0.0-alpha.2","v11.0.0-alpha.1","v10.0.0-rc.1","v10.0.0-beta.2","v10.0.0-beta.1","v9.0.0-beta.1","v8.0.0","v8.0.0-alpha.6","v8.0.0-alpha.5","v8.0.0-alpha.4","v8.0.0-alpha.3","v8.0.0-alpha.2","v8.0.0-alpha.1","v7.0.0-beta.1","v6.0.0-rc.2","v6.0.0-rc.1","v5.99.10","v4.99.5","v4.0.0","v3.99.12","v3.99.11","v3.99.10","v3.99.8","v3.0.1","v3.0.0","v2.9.1","v2.9.0","v2.0.0","v1.2","v1.1.2","v1.0.22","v1.0.21"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-41180.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/nextcloud/talk-android","events":[{"introduced":"0"},{"fixed":"55ffd210d100fb8036b8c11a0d5077a695f21a61"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:nextcloud:talk:*:*:*:*:*:android:*:*","extracted_events":[{"introduced":"0"},{"fixed":"12.1.2"}]}}],"versions":["v12.1.1","v12.1.0","v12.1.0rc2","v12.1.0rc1","alpha-120000016","alpha-120000015","alpha-120000014","alpha-120000013","alpha-","alpha-120000008","alpha-120000007","alpha-120000006","alpha-120000005","alpha-120000004","alpha-120000003","v11.0.0","alpha-120000002","alpha-110000006","alpha-110000005","alpha-110000004","alpha-110000002","v8.2.0","v8.1.0","v8.1.0rc1","v8.0.10","v8.0.9","v8.0.8","v8.0.7","v8.0.6","v8.0.5","v8.0.4","v8.0.3","v8.0.2","v8.0.1","v8.0.0","v8.0.0beta4","v8.0.0beta3","v8.0.0beta2","v8.0.0beta1","v7.0.8","v7.0.7","v7.0.6","v7.0.5","v7.0.4","v7.0.3","v7.0.2","v7.0.1","v7.0.0","v7.0.0beta5","v7.0.0beta4","v7.0.0beta3","v7.0.0beta2","v7.0.0beta1","v6.1.0","v6.0.7beta","v6.0.6internal","v6.0.6-internal","v6.0.2","v6.0.1","v6.0.0","v6.0.0beta4","v6.0.0beta3","v6.0.0beta2","v6.0.0beta1","v3.3.0beta3","v3.3.0beta2","v3.3.0beta1","v3.2.0beta5","v3.2.0beta4","v3.2.0beta3","v3.2.0beta2","v3.2.0beta1","v3.1.0","v3.1.0beta6","v3.1.0beta5","v3.1.0beta4","v3.1.0beta3","v3.1.0beta2","v3.1.0beta1","v3.0.1","v3.0.0","v3.0.0beta10","v3.0.0beta8","v3.0.0beta7","v3.0.0beta6","v3.0.0beta5","v3.0.0beta4","v3.0.0beta3","v3.0.0beta1","v2.1.0","v2.1.0beta5","v2.1.0beta4","v2.1.0beta3","v2.1.0beta2","v2.1.0beta1","v2.0.0","v2.0.0beta5","v2.0.0beta4","v1.2.0beta3","v1.2.0beta2","v1.2.0beta1","v1.1.1","v1.1.0","v1.1.0beta4","v1.1.0beta3","v1.1.0beta2","v1.1.0beta1","v1.0.14","v1.0.13","v1.0.12","v1.0.11","v1.0.10","v1.0.9","v1.0.8","v1.0.7","v1.0.6","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0","v0.2.0","v0.1.2","v0.1.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-41180.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
