Assent.Strategy.Apple.callback/2 in lib/assent/strategies/apple.ex decodes that parameter, and fetch_user/2 merges it over the claims of the verified ID token, so the unverified map wins. An attacker who completes a Sign in with Apple login with their own Apple ID and edits the user parameter can replace sub, email, and any other claim. Applications that look up, link, or authorize accounts by the returned subject or email then act on the attacker's values.\nThis issue affects assent: from 0.1.25 before 0.3.2.\nhttps://www.cve.org/CVERecord?id=CVE-2026-117656https://github.com/pow-auth/assent/security/advisories/GHSA-9fr5-g44g-9526https://cna.erlef.org/cves/CVE-2026-117656.htmlhttps://osv.dev/vulnerability/EEF-CVE-2026-117656https://github.com/pow-auth/assent/commit/a2d331e8c51376d6c0b04a81aad31e0b4d4d64a3https://github.com/pow-auth/assent/commit/18898bde0296152165ae470078490e5798329b1b#pow-auth #assent#CVE_2026_117656#bot", "url": "https://infosec.exchange/users/cve/statuses/117532592247645206"}, {"timestamp": "2026-10-31T00:16:51.340Z", "date_only": false, "value": "2026-10-31T00:16:51.340", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-117656", "record": "FKIE_CVE-2026-117656", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-10-31T02:07:48.920Z", "date_only": false, "value": "2026-10-31T02:07:48.920453Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/stemshop.bsky.social/post/3mz57klqses2p", "record": "CVE-2026-117656", "field": "creation_timestamp", "uuid": "e0ce1e66-bf57-4d80-ad92-bd01cc8869dc", "content": "\ud83d\udea8 CVE-2026-117656 \u2014 CVSS 9.3 CRITICAL\n\nAcceptance of Extraneous Untrusted Data With Trusted Data vulnerability in the Sign in with Apple strategy ...\n\n\ud83d\udd0e https://stemshop.top/cve/CVE-2026-117656\n\n#CVE #CyberSecurity #InfoSec", "url": "https://bsky.app/profile/stemshop.bsky.social/post/3mz57klqses2p"}, {"timestamp": "2026-10-31T19:34:45.444Z", "date_only": false, "value": "2026-10-31T19:34:45.444427Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/cvesentinel.bsky.social/post/44bplann6lz2n", "record": "CVE-2026-117656", "field": "creation_timestamp", "uuid": "e0c5c968-f009-4c46-8954-1c769e5d7d1e", "content": "\ud83d\udea8 CVE-2026-117656\nCVSS 9.3 / EPSS 0.23% / KEV: No\nTL;DR: Acceptance of Extraneous Untrusted Data With Trusted Data vulnerability in the Sign in with Apple strategy in pow-auth Assent allows an unauthenticated remote\u2026\nhttps://cvesentinel.com/report/CVE-2026-117656\n#infosec #CVE #vulnerability", "url": "https://bsky.app/profile/cvesentinel.bsky.social/post/44bplann6lz2n"}, {"timestamp": "2026-10-31T23:40:04.448Z", "date_only": false, "value": "2026-10-31T23:40:04.448230Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/stackflag.bsky.social/post/3mz7hrde5ds2w", "record": "CVE-2026-117656", "field": "creation_timestamp", "uuid": "d78f58e2-eb92-41cf-8c71-ed1c43822da1", "content": "CVE-2026-117656 - assent\nThe Assent library that handles Sign in with Apple lets a malicious web user change the information returned after a login.
