{"id":"GHSA-3vx2-vqx8-jxfg","summary":"@steipete/summarize vulnerable to SSRF via podcast:transcript URL fetch","details":"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.","aliases":["CVE-2026-53782"],"modified":"2026-08-20T18:48:09.211294Z","published":"2026-06-11T21:31:57Z","database_specific":{"cwe_ids":["CWE-918"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-08-20T18:33:58Z","nvd_published_at":"2026-06-11T20:16:25Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53782"},{"type":"WEB","url":"https://github.com/steipete/summarize/pull/239"},{"type":"WEB","url":"https://github.com/steipete/summarize/commit/3c5522440c4833dde033e226baa39e6dda1dfc75"},{"type":"PACKAGE","url":"https://github.com/steipete/summarize"},{"type":"WEB","url":"https://github.com/steipete/summarize/releases/tag/v0.17.0"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/summarize-ssrf-via-podcast-transcript-url-fetch"}],"affected":[{"package":{"name":"@steipete/summarize","ecosystem":"npm","purl":"pkg:npm/%40steipete/summarize"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.17.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-3vx2-vqx8-jxfg/GHSA-3vx2-vqx8-jxfg.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:N/PR:N/UI:P/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
