{"id":"CVE-2026-55879","summary":"OpenReplay: Unauthenticated stored XSS leads to dashboard account takeover","details":"OpenReplay is a self-hosted session replay suite. From 1.24.0 before 1.25.0, the OpenReplay tracking SDK accepts custom event names and captured page URLs from any visitor using a public project key, stores them in ClickHouse without output encoding, and later renders them in the authenticated dashboard through TextEllipsis and the event-details modal, allowing an unauthenticated attacker to store script that executes in the dashboard origin, reads the session JWT from localStorage, and takes over a dashboard account. This issue is fixed in version 1.25.0.","aliases":["GHSA-3mfc-7hf4-jfxh"],"modified":"2026-07-16T03:31:08.923909437Z","published":"2026-07-10T20:39:44.493Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55879.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-79"]},"references":[{"type":"WEB","url":"https://github.com/openreplay/openreplay/releases/tag/v1.25.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55879.json"},{"type":"ADVISORY","url":"https://github.com/openreplay/openreplay/security/advisories/GHSA-3mfc-7hf4-jfxh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55879"},{"type":"FIX","url":"https://github.com/openreplay/openreplay/commit/ec41f4425a99c478a4418adbd2f094ab6a8b0daf"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openreplay/openreplay","events":[{"introduced":"57503eec89bc34a3017917990f9296899e20c41c"},{"fixed":"ddac26e863353590b638b646c334255b80ea1a90"},{"fixed":"ec41f4425a99c478a4418adbd2f094ab6a8b0daf"}],"database_specific":{"extracted_events":[{"introduced":"1.24.0"},{"fixed":"1.25.0"}],"source":["DESCRIPTION","REFERENCES"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55879.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N"}]}
