This makes it possible for authenticated attackers, with custom-level access and above, to write arbitrary files on the server, which can allow for remote code execution. The install_app, update_app, and get_kirki_template_from_zip code paths accept a user-supplied app src value to construct the download URL, and no sanitization is applied to prevent a crafted ZIP from being fetched and extracted with path-traversing entry names that escape the intended destination directory.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N","score":4.9},"cwes":["CWE-22"],"references":["https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.12/app/Http/Controllers/Api/AppsController.php#L27","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.12/app/Services/AppsService.php#L113","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.12/app/Services/AppsService.php#L186","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.12/app/Supports/FileHandler.php#L90","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.12/includes/Ajax/Apps.php#L176"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-15601","score":0.0114,"percentile":0.66638,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
