Prior to versions 4.2.7, 4.1.15, 4.0.15, and 3.5.19, when fetching remote statuses, Mastodon doesn't check that the response from the remote server has a `Content-Type` header value of the Activity Streams media type, which allows a threat actor to upload a crafted Activity Streams document to a remote server and make a Mastodon server fetch it, if the remote server accepts arbitrary user uploads. The vulnerability allows a threat actor to impersonate an account on a remote server that satisfies all of the following properties: allows the attacker to register an account; accepts arbitrary user-uploaded documents and places them on the same domain as the ActivityPub actors; and serves user-uploaded document in response to requests with an `Accept` header value of the Activity Streams media type. Versions 4.2.7, 4.1.15, 4.0.15, and 3.5.19 contain a fix for this issue."}],"source":{"advisory":"GHSA-jhrq-qvrm-qr36","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-25623","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-02-20T18:34:37.609043Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-07-05T17:21:47.723Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-01T23:44:09.828Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/mastodon/mastodon/security/advisories/GHSA-jhrq-qvrm-qr36","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/mastodon/mastodon/security/advisories/GHSA-jhrq-qvrm-qr36"},{"name":"https://github.com/mastodon/mastodon/commit/9fee5e852669e26f970e278021302e1a203fc022","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/mastodon/mastodon/commit/9fee5e852669e26f970e278021302e1a203fc022"}]}]}}
