{"id":"CVE-2026-53497","summary":"CrossWatch: Unauthenticated /api/app-auth/status endpoint leaks active session metadata (IP, User-Agent, session IDs)","details":"CrossWatch (CW) is a synchronization engine. Prior to version 0.9.21, GET /api/app-auth/status is accessible without authentication and returns the other_sessions array, which exposes metadata of all active sessions — including originating IP addresses, User-Agent strings, internal session IDs, and creation/expiry timestamps. Any unauthenticated network attacker can enumerate this data without credentials. Version 0.9.21 fixes the issue.","aliases":["GHSA-rv3j-r4h5-q3cj"],"modified":"2026-08-23T03:53:39.323422354Z","published":"2026-08-21T21:19:04.535Z","database_specific":{"cwe_ids":["CWE-200","CWE-359"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53497.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/cenodude/CrossWatch/releases/tag/v0.9.21"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53497.json"},{"type":"ADVISORY","url":"https://github.com/cenodude/CrossWatch/security/advisories/GHSA-rv3j-r4h5-q3cj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53497"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/cenodude/crosswatch","events":[{"introduced":"0"},{"fixed":"e3d624eb6a86516f911e40cf062cd645a6c44e33"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.9.21"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v0.9.20","v0.9.19","v0.9.18","v0.9.17","v0.9.16","v0.9.15","v0.9.14","v0.9.13","v0.9.12","v0.9.11","v0.9.10","v0.9.9","v0.9.8","v0.9.7","v0.9.6","v0.9.5","v0.9.4","v0.9.3","v0.9.2","v0.9.1","v0.9.0","v0.8.2","v0.8.1","v0.8.0","v0.7.8","v0.7.7","v0.7.6","v0.7.5","v0.7.4","v0.7.3","v0.7.2","v0.7.1","v0.7.0","v0.6.4","v0.6.3","v0.6.2","v0.6.1","v0.6.0","v0.5.8","v0.5.7","v0.5.6","v0.5.5","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.9","v0.4.8","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.9","v0.3.2","v0.3.1","v0.3.0","v0.2.20","v0.2.19","v0.2.18","v0.2.17","v0.2.16","v0.2.15","v0.2.14","v0.2.13","v0.2.12","v0.2.11","v0.2.10","v0.2.9","v0.2.8","v0.2.7","v0.2.6","v0.2.5","v0.2.4","v0.2.3","v0.2.2","v0.2.1","v0.2.0","v0.1.7","v0.1.6","v0.1.5","v0.1.4","v0.1.3","v0.1.2","v0.1.1","v0.1.0","v0.0.9","v0.0.8","v0.0.7","v0.0.6","v0.0.5","v0.0.4","v0.0.3","v0.0.2","v0.0.1","v"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53497.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
