Description OSIDB Bzimport 2026-11-11 18:51:32 UTC
Spatie Browsershot 2.2.0 before 5.5.0 contains a local file read vulnerability that allows attackers to read server files by supplying root-relative references in HTML passed to setHtml(). Attackers can embed iframe, img, link or script elements referencing paths like /etc/passwd, which resolve to file:// URLs and render file contents into the returned PDF or screenshot.
