A directory whose name merely begins with an allowed path therefore satisfies the comparison, so where /data/images is allowed a request for /data/images_private/secret.txt is treated as trusted and served by FileResponse, disclosing files the confinement was meant to exclude. Whether the check applies depends on get_enable_access_control in scripts/iib/tool.py: it returns true when IIB_ACCESS_CONTROL is set to enable, false when set to disable, and otherwise true when the host Stable Diffusion WebUI was started with share, ngrok, listen or server_name, falling back to false. Confinement is therefore active in the network-exposed WebUI deployments that rely on it, while a standalone run with no such option serves every readable file regardless of this flaw. The fix compares against parent_path joined with os.sep.","epss":{"date":"2026-11-08","percentile":0.4336,"score":0.00504},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://github.com/zanllp/infinite-image-browsing/issues/968"}],"kev":null,"metrics":[{"score":8.7,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},{"score":7.5,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"}],"modifiedAt":1794146941731,"publishedAt":1787324588589,"references":[{"source":"CNA: VulnCheck","tags":["issue-tracking"],"url":"https://github.com/zanllp/infinite-image-browsing/issues/968"},{"source":"CNA: VulnCheck","tags":["issue-tracking","patch"],"url":"https://github.com/zanllp/infinite-image-browsing/pull/969"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/zanllp/infinite-image-browsing/commit/4057a624c7a23a36f0b4dc6a545b40767d602450"},{"source":"CNA: VulnCheck","tags":["technical-description"],"url":"https://github.com/zanllp/infinite-image-browsing/blob/v1.8.0/scripts/iib/api.py#L329-L344"},{"source":"CNA: VulnCheck","tags":["product"],"url":"https://github.com/zanllp/infinite-image-browsing"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/infinite-image-browsing-is-path-trusted-prefix-comparison-omits-the-trailing-path-separator"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://github.com/zanllp/infinite-image-browsing/issues/968"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
