{"id":"CVE-2024-2435","summary":"Stored XSS in Timeline View","details":"For an attacker with pre-existing access to send a signal to a workflow, the attacker can make the signal name a script that executes when a victim views that signal. The XSS is in the timeline page displaying the workflow execution details of the workflow that was sent the crafted signal.\nAccess to send a signal to a workflow is determined by how you configured the authorizer on your server. This includes any entity with permission to directly call SignalWorkflowExecution or SignalWithStartWorkflowExecution, or any entity can deploy a worker that has access to call workflow progress APIs (specifically RespondWorkflowTaskCompleted).\n","aliases":["GHSA-8f25-w7qj-r7hc","GO-2024-2675"],"modified":"2026-08-12T03:51:28.187039485Z","published":"2024-04-02T16:40:24.552Z","related":["CGA-xxv7-fqj5-m886"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/2xxx/CVE-2024-2435.json","cna_assigner":"Temporal","cwe_ids":["CWE-79"]},"references":[{"type":"WEB","url":"https://hub.docker.com/r/temporalio/ui"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/2xxx/CVE-2024-2435.json"},{"type":"ADVISORY","url":"https://github.com/temporalio/ui-server/releases/tag/v2.25.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-2435"},{"type":"PACKAGE","url":"https://github.com/temporalio/ui-server"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/temporalio/ui-server","events":[{"introduced":"70a7375d51cc7a40bfc7ff594a00d7ebda8f7d78"},{"fixed":"fe4d88a3477e7c01bad0ab761853e87e3e472b01"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"2.16.2"},{"fixed":"2.25.0"}]}}],"versions":["v2.24.0","v2.23.0","v2.22.3","v2.22.2","v2.22.1","v2.22.0","v2.21.4","v2.21.3","v2.21.2","v2.21.1","v2.21.0","v2.20.0","v2.19.0","v2.18.2","v2.18.1","v2.18.0","v2.17.2","v2.17.1","v2.17.0","v2.16.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-2435.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:L/A:L"}]}
