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.","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":4.6},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N","score":7.4},"cwes":["CWE-918","CWE-940"],"references":["https://github.com/steipete/summarize/commit/ecbb2c414255aa480a15d0d8b205224c14cfdbcb","https://github.com/steipete/summarize/pull/218","https://github.com/steipete/summarize/releases/tag/v0.15.2","https://www.vulncheck.com/advisories/summarize-unauthorized-daemon-request-via-untrusted-events","https://github.com/steipete/summarize/pull/218"],"products":["steipete:summarize"],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-45245","score":0.0033,"percentile":0.25898,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-2r69-qgv3-hr65","url":"https://osv.dev/vulnerability/GHSA-2r69-qgv3-hr65","summary":"Summarize's hover summary feature allows malicious pages to dispatch synthetic mouseover events over attacker-controlled links","modified":"2026-09-10T03:51:04.147271565Z","packages":[{"ecosystem":"npm","name":"@steipete/summarize","purl":"pkg:npm/%40steipete/summarize","ranges":["<0.15.1"],"fixed":["0.15.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
