Last modified

CVE-2026-45242 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. Summarize prior to 0.15.1 contains a path traversal vulnerability in the /v1/summarize daemon endpoint that allows authenticated callers to write files to arbitrary directories by supplying an absolute path or directory traversal sequence in the slidesDir request parameter. Attackers can exploit this to write slide_*.png and slides.json files to any writable directory and subsequently delete matching files at the specified location through repeat extraction.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
