DescriptionNVD

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.

AnalysisAI

Path traversal in steipete/summarize prior to 0.15.1 lets authenticated callers of the /v1/summarize daemon endpoint write slide_*.png and slides.json files to arbitrary directories by supplying an absolute path or traversal sequences in the slidesDir parameter, and subsequently delete matching files via repeat extraction. The flaw, reported by VulnCheck and patched in v0.15.2, enables file write and limited destructive impact across the filesystem; no public exploit identified at time of analysis.
