BIT-mastodon-2026-50128: Mastodon: Spoofing of attribution domainsCVE-2026-50128
0

Mastodon versions from 4.3.0 up to but not including 4.4.18, and from 4.5.0 up to but not including 4.5.11, contain a vulnerability in the handling of attributionDomains in JSON-LD. This flaw allows an attacker to modify the attributionDomains value in a legitimately signed Update activity, bypassing Mastodon's signature verification and enabling spoofing of attribution domains. The issue is fixed in versions 4.4.18 and 4.5.11.
