{"id":"CVE-2026-75599","published":"2026-11-05T17:18:20.340","lastModified":"2026-11-05T17:18:20.340","description":"HomeBox is a home inventory and organization system. Prior to 0.27.0, the maybeUrl() utility accepts markdown-style links in entity custom-field values without restricting the URL scheme, so an authenticated user can store a javascript: URI that is rendered as a clickable anchor on an item page. When another authenticated user clicks the link, attacker-controlled JavaScript executes in the victim's HomeBox origin, enabling session theft, account takeover, or data exfiltration. This issue is fixed in version 0.27.0.","cvssScore":5.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/sysadminsmedia/homebox/commit/d76b1c9b94e91cd74e56ef8a129325d70835471f","tags":[]},{"url":"https://github.com/sysadminsmedia/homebox/releases/tag/v0.27.0","tags":[]},{"url":"https://github.com/sysadminsmedia/homebox/security/advisories/GHSA-h4x5-6587-jpwp","tags":[]}],"exploitRefs":[{"url":"https://github.com/sysadminsmedia/homebox/commit/d76b1c9b94e91cd74e56ef8a129325d70835471f","tags":[]},{"url":"https://github.com/sysadminsmedia/homebox/releases/tag/v0.27.0","tags":[]},{"url":"https://github.com/sysadminsmedia/homebox/security/advisories/GHSA-h4x5-6587-jpwp","tags":[]}],"hasPoc":true,"ai":null}
