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.","state":0,"publishedAt":"2026-05-18T21:31:51+00:00","modifiedAt":"2026-09-10T03:51:04.1472716+00:00","affected":[{"ecosystem":"npm","name":"@steipete/summarize","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"0.15.1"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N","score":null,"severity":null},{"system":"CVSS_V4","vector":"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","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://nvd.nist.gov/vuln/detail/CVE-2026-45245","https://github.com/steipete/summarize/pull/218","https://github.com/steipete/summarize/commit/ecbb2c414255aa480a15d0d8b205224c14cfdbcb","https://github.com/steipete/summarize","https://github.com/steipete/summarize/releases/tag/v0.15.1","https://github.com/steipete/summarize/releases/tag/v0.15.2","https://www.vulncheck.com/advisories/summarize-unauthorized-daemon-request-via-untrusted-events"],"sourceUrl":"https://github.com/advisories/GHSA-2r69-qgv3-hr65","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-2r69-qgv3-hr65","identifiers":["GHSA-2r69-qgv3-hr65","CVE-2026-45245"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
