Title
Bio-Formats <= 8.3.0 XXE in Leica XLEF Metadata Parser
Summary
Bio-Formats versions up to and including 8.3.0 contain an XML External Entity (XXE) vulnerability in the Leica Microsystems metadata parsing component (e.g., XLEF). The parser uses an insecurely configured DocumentBuilderFactory when processing Leica XML-based metadata files, allowing external entity expansion and external DTD loading. A crafted metadata file can trigger outbound network requests (SSRF), access local system resources where readable, or cause a denial of service during XML parsing.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
