Official Description

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.

Technical Analysis

CVE-2026-45242 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in full integrity compromise (data manipulation), with a CVSS base score of 7.1.
