CVE-2026-109166
validatedZero produced an exploit or a check.GHSA-xv2w-mrmf-rf3c ↗EUVD-2026-97372 ↗
description
lamp-cloud through 5.10.1 does not enforce ownership checks when retrieving storage URLs for uploaded files. An authenticated attacker who knows or can supply another user's file identifier may obtain an access URL and read that user's attachments.
mitigation
Upgrade to a vendor release that adds ownership authorization checks when one is available. Until then, restrict access to affected file URL retrieval functionality and enforce server-side ownership checks before returning storage URLs.
outcome
Contextual check: a technique exists and was validated, but no deterministic check could cover this one.
