{"id":"CVE-2024-21636","summary":"view_component Cross-site Scripting vulnerability","details":"view_component is a framework for building reusable, testable, and encapsulated view components in Ruby on Rails. Versions prior to 3.9.0 and 2.83.0 have a cross-site scripting vulnerability that has the potential to impact anyone rendering a component directly from a controller with the view_component gem. Note that only components that define a `#call` method (i.e. instead of using a sidecar template) are affected. The return value of the `#call` method is not sanitized and can include user-defined content. In addition, the return value of the `#output_postamble` methodis not sanitized, which can also lead to cross-site scripting issues. Versions 3.9.0 and 2.83.0 have been released and fully mitigate both the `#call` and the `#output_postamble` vulnerabilities. As a workaround, sanitize the return value of `#call`.","aliases":["GHSA-wf2x-8w6j-qw37"],"modified":"2026-08-12T03:51:36.245758597Z","published":"2024-01-04T20:09:08.564Z","database_specific":{"cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/21xxx/CVE-2024-21636.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/21xxx/CVE-2024-21636.json"},{"type":"ADVISORY","url":"https://github.com/ViewComponent/view_component/security/advisories/GHSA-wf2x-8w6j-qw37"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-21636"},{"type":"FIX","url":"https://github.com/ViewComponent/view_component/commit/0d26944a8d2730ea40e60eae23d70684483e5017"},{"type":"FIX","url":"https://github.com/ViewComponent/view_component/commit/c43d8bafa7117cbce479669a423ab266de150697"},{"type":"FIX","url":"https://github.com/ViewComponent/view_component/pull/1950"},{"type":"FIX","url":"https://github.com/ViewComponent/view_component/pull/1962"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/viewcomponent/view_component","events":[{"introduced":"0"},{"fixed":"ab407af583fe9221931431ef3d575850b9e88008"},{"introduced":"c696930250b696fb5528be08edea13a0c78b8325"},{"fixed":"c8462c2113ca1771b681fc89eb025d8e8b685727"},{"fixed":"0d26944a8d2730ea40e60eae23d70684483e5017"},{"fixed":"c43d8bafa7117cbce479669a423ab266de150697"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.83.0"},{"introduced":"3.0.0"},{"fixed":"3.9.0"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:viewcomponent:view_component:*:*:*:*:*:ruby:*:*"}}],"versions":["v2.82.0","v3.8.0","v3.7.0","v3.6.0","v3.5.0","v3.3.0","v3.2.0","v3.1.0","v3.0.0","v2.81.0","v2.80.0","v2.79.0","v2.78.0","v2.77.0","v2.76.0","v2.75.0","v2.74.1","v2.74.0","show","v2.73.0","v2.72.0","v2.71.0","v2.70.0","v2.69.0","v2.68.0","v2.67.0","v2.66.0","v2.65.0","v2.64.0","v2.63.0","v2.62.0","v2.61.1","v2.61.0","v2.60.0","v2.59.0","v2.58.0","v2.57.1","v2.57.0","v2.56.2","v2.56.1","v2.56.0","v2.55.0","v2.54.1","v2.54.0","v2.53.0","v2.52.0","v2.51.0","v2.50.0","v2.31.1","v2.49.0","v2.48.0","v2.47.0","v2.46.0","v2.45.0","v2.44.0","v2.43.1","v2.43.0","v2.42.0","v2.41.0","v2.40.0","v2.39.0","v2.38.0","v2.37.0","v2.36.0","v2.35.0","v2.34.0","v2.33.0","v2.32.0","v2.31.0","v2.30.0","v2.29.0","v2.28.0","v2.27.0","v2.26.1","v2.26.0","v2.25.1","v2.25.0","v2.24.0","v2.23.2","v2.23.1","2.23.0","v2.22.1","v2.22.0","v2.21.0","v2.20.0","v2.19.1","v2.19.0","v2.18.2","v2.18.1","v2.18.0","v2.17.1","v2.17.0","v2.16.0","v2.15.0","v2.14.1","v2.14.0","v2.13.0","v2.12.0","v2.11.1","v2.11.0","v2.10.0","v2.9.0","v2.8.0","v2.7.0","v2.6.0","v2.5.1","v2.5.0","v2.4.0","v2.3.0","v2.2.2","v2.2.1","v2.2.0","v2.1.0","v2.0.0","v1.17.0","v1.16.0","v1.15.0","v1.14.1","v1.14.0","v1.13.0","v1.12.0","v1.11.1","v1.11.0","v1.10.0","v1.9.0","v1.8.1","v1.8.0","v1.1","v1.7.0","v1.6.2","v1.6.1","v1.6.0","v1.5.3","v1.5.2","v1.5.1","v1.5.0","v1.4.0","v1.3.6","v1.3.5","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3.0","v1.2.1","v1.2.0","v1.1.0","v1.0.1","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-21636.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
