BIT-mastodon-2026-46349: Mastodon: LD-Signature Bypass via JSON-LD Named-Graph RestructuringCVE-2026-46349 0 Mastodon versions prior to 4.5.10, 4.4.17, and 4.3.23 have a vulnerability in the normalization of incoming activities signed with Linked-Data Signatures. This flaw allows attackers to rearrange a valid signed JSON-LD activity from a third party so that it is processed differently, potentially bypassing signature validation. The issue is fixed in versions 4.5.10, 4.4.17, and 4.3.23. Join the discussion | GCVE Database | 07/06/2026, 05:55:15 UTC Added: 07/06/2026, 23:04:20 UTC |
