{"id":"CVE-2026-49436","summary":"LinkAce vulnerable to stored XSS via 'javascript:' URI in Bulk Link API","details":"LinkAce is a self-hosted archive to collect website links. Prior to version 2.5.7, the Bulk Link API endpoint (`POST /api/v2/bulk/links`) accepts URLs without any format validation, allowing an authenticated user to store a `javascript:` URI. The stored URI is later rendered verbatim as an `href` in Blade templates, and clicking it executes arbitrary JavaScript in the victim's browser — exfiltrating cookies and session tokens. Version 2.5.7 fixes the issue.","aliases":["GHSA-6r73-pchm-4m39"],"modified":"2026-08-23T03:42:54.924678002Z","published":"2026-08-20T21:40:54.087Z","database_specific":{"cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49436.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49436.json"},{"type":"ADVISORY","url":"https://github.com/Kovah/LinkAce/security/advisories/GHSA-6r73-pchm-4m39"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49436"},{"type":"FIX","url":"https://github.com/Kovah/LinkAce/commit/642ac520347205a8277668bcae269bdc21223eae"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kovah/linkace","events":[{"introduced":"0"},{"fixed":"642ac520347205a8277668bcae269bdc21223eae"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.5.7"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v2.5.6","v2.5.5","v2.5.4","v2.5.3","v2.5.2","v2.5.1","v2.5.0","v2.4.3","v2.4.2","v2.4.1","v2.4.0","v2.3.1","v2.3.0","v2.2.0","v2.1.9","v2.1.8","v2.1.7","v2.1.6","v2.1.5","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1.0","v2.0.0","v2.0.0-beta4","v2.0.0-beta3","v2.0.0-beta2","v2.0.0-beta1","v1.10.1","v1.10.0","v1.9.2","v1.9.1","v1.9.0","v1.8.1","v1.8.0","v1.7.0","v1.6.4","v1.6.3","v1.6.2","v1.6.1","v1.6.0","v1.5.0","v1.4.1","v1.4.0","v1.3.1","v1.3.0","v1.2.2","v1.2.1","v1.2.0","v1.1.0","v1.0.1","v1.0.0","v0.0.44","v0.0.43","v0.0.42","v0.0.41","v0.0.40","v0.0.39","v0.0.38","v0.0.37","v0.0.36","v0.0.35","v0.0.34","v0.0.33","v0.0.32","v0.0.31","v0.0.30","v0.0.29","v0.0.28","v0.0.27","v0.0.26","v0.0.25","v0.0.24","v0.0.23","v0.0.22","v0.0.21","v0.0.20","v0.0.19","v0.0.18","v0.0.17","v0.0.16","v0.0.15","v0.0.14","v0.0.13","v0.0.12","v0.0.11","v0.0.10","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"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-49436.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N"}]}
