{"id":"GHSA-2r69-qgv3-hr65","summary":"Summarize's hover summary feature allows malicious pages to dispatch synthetic mouseover events over attacker-controlled links","details":"Summarize prior to 0.15.0 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.","aliases":["CVE-2026-45245"],"modified":"2026-09-10T03:51:04.147271565Z","published":"2026-05-18T21:31:51Z","database_specific":{"cwe_ids":["CWE-918"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-05-29T20:00:00Z","nvd_published_at":"2026-05-18T20:16:38Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45245"},{"type":"WEB","url":"https://github.com/steipete/summarize/pull/218"},{"type":"WEB","url":"https://github.com/steipete/summarize/commit/ecbb2c414255aa480a15d0d8b205224c14cfdbcb"},{"type":"PACKAGE","url":"https://github.com/steipete/summarize"},{"type":"WEB","url":"https://github.com/steipete/summarize/releases/tag/v0.15.1"},{"type":"WEB","url":"https://github.com/steipete/summarize/releases/tag/v0.15.2"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/summarize-unauthorized-daemon-request-via-untrusted-events"}],"affected":[{"package":{"name":"@steipete/summarize","ecosystem":"npm","purl":"pkg:npm/%40steipete/summarize"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.15.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-2r69-qgv3-hr65/GHSA-2r69-qgv3-hr65.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:N/SC:H/SI:N/SA:N"}]}
