Prior to 1.3.1-stable and 1.3.9-beta, attacker-controlled path input is joined with a trusted base path prior to sanitization, allowing traversal sequences (e.g., ..\/) to escape the intended shared directory. As a result, an unauthenticated attacker possessing a valid public share hash with delete permissions enabled can delete arbitrary files outside the shared directory within the share owner\u2019s configured storage scope. This affects public\/api\/resources and public\/api\/resources\/bulk. This vulnerability is fixed in 1.3.1-stable and 1.3.9-beta.<\/p>\n<p>  Severity: 9.1 | CRITICAL<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-44542 Published : May 14, 2026, 6:16 p.m. | 27\u00a0minutes ago Description :FileBrowser Quantum is a free, self-hosted, web-based file manager.
