Prior to 1.7.4, joserfc.jws.deserialize_json() accepts a JWS General JSON Serialization with an empty signatures array as authenticated. The verify_general_json() loop performs no iterations for the empty array and returns success because no signature check failed, allowing an attacker without a signing key to supply an arbitrary payload that relying applications may treat as authentic. The issue affects the General JSON Serialization path; compact JWS and JWT decoding, Flattened JSON serialization, and JWE JSON processing do not follow this vulnerable path. This issue is fixed in version 1.7.4.\nhttps://www.cve.org/CVERecord?id=CVE-2026-102946https://github.com/authlib/joserfc/security/advisories/GHSA-4pp3-559j-c5c2https://github.com/authlib/joserfc/commit/f409f8f058225d7686acab6546c94593e4c1bfbehttps://github.com/authlib/joserfc/releases/tag/1.7.4#authlib #joserfc#CVE_2026_102946#bot", "url": "https://infosec.exchange/users/cve/statuses/117446383596934235"}, {"timestamp": "2026-10-15T19:17:13.423Z", "date_only": false, "value": "2026-10-15T19:17:13.423", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-102946", "record": "FKIE_CVE-2026-102946", "field": "published"}, {"timestamp": "2026-10-15T19:40:04.502Z", "date_only": false, "value": "2026-10-15T19:40:04.502241Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/stackflag.bsky.social/post/3mxwsvgwps42l", "record": "CVE-2026-102946", "field": "creation_timestamp", "uuid": "a368fee0-8cbc-4c2a-b25a-af429b6e564e", "content": "CVE-2026-102946 - joserfc\nThe joserfc Python library (versions before 1.7.4) can treat a specially crafted JSON message with no signatures as valid.
