{"id":"CVE-2026-53782","aliases":["GHSA-3vx2-vqx8-jxfg"],"url":"https://o3.security/vulnerability/CVE-2026-53782","summary":"Summarize < 0.17.0 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.","published":"2026-06-11T19:17:19.575Z","modified":"2026-08-20T18:48:09.211294961Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"@steipete/summarize","fixedVersion":"0.17.0"}],"fix":{"url":"https://github.com/steipete/summarize/commit/3c5522440c4833dde033e226baa39e6dda1dfc75","label":"steipete/summarize@3c55224"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53782.json"},{"type":"ADVISORY","url":"https://github.com/steipete/summarize/releases/tag/v0.17.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53782"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/summarize-ssrf-via-podcast-transcript-url-fetch"},{"type":"REPORT","url":"https://github.com/steipete/summarize/pull/239"},{"type":"FIX","url":"https://github.com/steipete/summarize/commit/3c5522440c4833dde033e226baa39e6dda1dfc75"},{"type":"PACKAGE","url":"https://github.com/steipete/summarize"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-20T18:48:09.211294961Z"}}
