{"id":"CVE-2026-45245","summary":"Summarize \u003c 0.15.1 Unauthorized Daemon Request via Untrusted Events","details":"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.","aliases":["GHSA-2r69-qgv3-hr65"],"modified":"2026-08-12T03:51:45.305404862Z","published":"2026-05-18T19:00:54.115Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45245.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-918","CWE-940"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45245.json"},{"type":"ADVISORY","url":"https://github.com/steipete/summarize/releases/tag/v0.15.2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45245"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/summarize-unauthorized-daemon-request-via-untrusted-events"},{"type":"REPORT","url":"https://github.com/steipete/summarize/pull/218"},{"type":"FIX","url":"https://github.com/steipete/summarize/commit/ecbb2c414255aa480a15d0d8b205224c14cfdbcb"},{"type":"PACKAGE","url":"https://github.com/steipete/summarize"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/steipete/summarize","events":[{"introduced":"0"},{"fixed":"8db0d04f38ba0cfeec805547f7ad58052bd3cf5f"},{"fixed":"ecbb2c414255aa480a15d0d8b205224c14cfdbcb"},{"fixed":"e34ce25c05e3c21aca7876695d6d64c00cca7a6e"}],"database_specific":{"cpe":"cpe:2.3:a:steipete:summarize:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"0.15.1"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v0.15.1","v0.15.0","v0.14.1","v0.14.0","v0.13.1","v0.13.0","v0.12.0","v0.11.1","v0.10.0","v0.9.0","v0.8.2","v0.7.1","v0.7.0","v0.6.1","v0.6.0","v0.5.0","v0.4.0","v0.3.0","v0.2.0","v0.1.2","v0.1.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45245.json"}}],"schema_version":"1.9.0","severity":[{"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"}]}
