CVE-2026-108603: Addsumtech Slide-Maker

Low severity, CVSS 3.3.

slide-maker through 5.8.0 contains a path traversal vulnerability in generate_images_openai.py that allows attackers to write image files outside the output directory via manifest-supplied filenames. Attackers can influence deck source material so the image prompt manifest contains ../ or symlinked filenames, creating directories and overwriting existing files at arbitrary paths.

Affected products

• Addsumtech Slide-Maker: up to and including 5.8.0
