{"id":"CVE-2026-109162","published":"2026-10-13T10:17:15.463","lastModified":"2026-10-16T19:56:15.773","description":"Forms using FileUpload or ImageUpload elements with a custom saveToFileMount configured stored uploaded files in the default storage folder 1:/user_upload/ instead of the configured destination. This could cause uploaded files to end up in a publicly accessible storage even though a restricted, non-public storage had been configured. Files stored this way are served directly, without the access checks applied to non-public storages. Forms that use the default value for saveToFileMount are not affected. This issue affects TYPO3 CMS versions 14.0.0-14.3.8.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-552","CWE-696"],"vendors":[],"products":[],"references":[{"url":"https://github.com/TYPO3/typo3/commit/cc3e8e28b0e830aaf6ad857272f3f2dc3c4ede12","tags":[]},{"url":"https://github.com/TYPO3/typo3/commit/f536f75c6bd3456165e4200e5df1b236ddeae3b0","tags":[]},{"url":"https://news.typo3.com/security/advisory/typo3-core-sa-2026-024","tags":[]}],"exploitRefs":[{"url":"https://github.com/TYPO3/typo3/commit/cc3e8e28b0e830aaf6ad857272f3f2dc3c4ede12","tags":[]},{"url":"https://github.com/TYPO3/typo3/commit/f536f75c6bd3456165e4200e5df1b236ddeae3b0","tags":[]}],"hasPoc":true,"ai":null}
