Summarize before 0.17.0 contains a server-side request forgery vulnerability that allows attackers who control a podcast RSS feed to direct the host to fetch transcript content from loopback addresses, link-local addresses, RFC 1918 private ranges, or other reserved destinations by supplying malicious podcast:transcript URL values. Attackers can bypass protections through DNS rebinding and redirect-based techniques, as redirect targets are not revalidated and hostnames are not resolved before request dispatch, exposing internal service responses through the summarization flow.

Summarize before 0.17.0 contains a resource exhaustion vulnerability that allows remote attackers to cause disk exhaustion by serving media responses that bypass the enforced size limit through missing or misreported Content-Length headers, chunked transfer encoding, or failed HEAD requests. Attackers who control a podcast feed or media URL can stream an unbounded response to local storage via the temp-file download path, exhausting disk or system resources on the host running the CLI.

Summarize prior to 0.15.1 contains an insecure file permission vulnerability in the refresh-free configuration rewrite path that allows local users to read sensitive credentials by exploiting default filesystem permissions. When the refresh-free path rewrites the configuration file, it creates the replacement with default process umask permissions instead of preserving the original file permissions, exposing the config file containing API keys and provider credentials to other local users on shared Unix-like systems.

Summarize prior to 0.15.1 contains a vulnerability in the hover summary feature that allows malicious pages to dispatch synthetic mouseover events over attacker-controlled links, causing the extension to make authenticated daemon requests using stored tokens without verifying event trustworthiness. Attackers can place local or private-network URLs behind hoverable links to route authenticated requests through the daemon, potentially accessing sensitive internal endpoints when users interact with attacker-controlled content.

Summarize prior to 0.15.1 contains a missing authorization vulnerability that allows attackers to execute browser automation actions without per-call user approval when the extension automation feature is enabled. Attackers can influence the agent through malicious page or summary content to invoke enabled extension automation tools such as navigation or debugger-backed actions, bypassing the final user approval step when a user interacts with attacker-controlled content.

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.

Summarize prior to 0.15.1 contains a missing authorization vulnerability in the content script window.postMessage bridge that allows malicious pages to perform unauthorized operations on automation artifacts. Attackers can simulate runtime messages with spoofed sender identifiers to list, read, create, overwrite, or delete automation artifacts scoped to the affected tab without proper authorization checks.

Summarize versions through 0.14.1, fixed in commit 0cfb0fb, creates the daemon configuration directory and file with default filesystem permissions that may be world-readable on Unix-like systems, allowing local attackers to read bearer tokens and API credentials stored in ~/.summarize/daemon.json. A local attacker can exploit these permissive permissions to read the daemon bearer token and persisted provider credentials, enabling unauthorized access to the daemon or recovery of sensitive API keys.
