Severity ?
5.4 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N
CWE
  • CWE-20 - Improper Input Validation
Summary
Mastodon is a free, open-source social network server based on ActivityPub. Starting in version 2.6.0 and prior to versions 3.5.9, 4.0.5, and 4.1.3, an attacker can craft a verified profile link using specific formatting to conceal arbitrary parts of the link, enabling it to appear to link to a different URL altogether. The link is visually misleading, but clicking on it will reveal the actual link. This can still be used for phishing, though, similar to IDN homograph attacks. Versions 3.5.9, 4.0.5, and 4.1.3 contain a patch for this issue.

Starting in version 2.6.0 and prior to versions 3.5.9, 4.0.5, and 4.1.3, an attacker can craft a verified profile link using specific formatting to conceal arbitrary parts of the link, enabling it to appear to link to a different URL altogether. The link is visually misleading, but clicking on it will reveal the actual link. This can still be used for phishing, though, similar to IDN homograph attacks. Versions 3.5.9, 4.0.5, and 4.1.3 contain a patch for this issue.\"}], \"source\": {\"advisory\": \"GHSA-55j9-c3mp-6fcq\", \"discovery\": \"UNKNOWN\"}}, \"adp\": [{\"providerMetadata\": {\"orgId\": \"af854a3a-2127-422b-91ae-364da2661108\", \"shortName\": \"CVE\", \"dateUpdated\": \"2024-08-02T16:45:57.097Z\"}, \"title\": \"CVE Program Container\", \"references\": [{\"name\": \"https://github.com/mastodon/mastodon/security/advisories/GHSA-55j9-c3mp-6fcq\", \"tags\": [\"x_refsource_CONFIRM\", \"x_transferred\"], \"url\": \"https://github.com/mastodon/mastodon/security/advisories/GHSA-55j9-c3mp-6fcq\"}, {\"name\": \"https://github.com/mastodon/mastodon/commit/610731b03dfcadd887078cb0399f4e514aa1931c\", \"tags\": [\"x_refsource_MISC\", \"x_transferred\"], \"url\": \"https://github.com/mastodon/mastodon/commit/610731b03dfcadd887078cb0399f4e514aa1931c\"}, {\"name\": \"https://github.com/mastodon/mastodon/releases/tag/v3.5.9\", \"tags\": [\"x_refsource_MISC\", \"x_transferred\"], \"url\": \"https://github.com/mastodon/mastodon/releases/tag/v3.5.9\"}, {\"name\": \"https://github.com/mastodon/mastodon/releases/tag/v4.0.5\", \"tags\": [\"x_refsource_MISC\", \"x_transferred\"], \"url\": \"https://github.com/mastodon/mastodon/releases/tag/v4.0.5\"}, {\"name\": \"https://github.com/mastodon/mastodon/releases/tag/v4.1.3\", \"tags\": [\"x_refsource_MISC\", \"x_transferred\"], \"url\": \"https://github.com/mastodon/mastodon/releases/tag/v4.1.3\"}]}, {\"title\": \"CISA ADP Vulnrichment\", \"metrics\": [{\"other\": {\"type\": \"ssvc\", \"content\": {\"id\": \"CVE-2023-36462\", \"role\": \"CISA Coordinator\", \"options\": [{\"Exploitation\": \"none\"}, {\"Automatable\": \"no\"}, {\"Technical Impact\": \"partial\"}], \"version\": \"2.0.3\", \"timestamp\": \"2024-10-24T14:21:58.873405Z\"}}}], \"providerMetadata\": {\"orgId\": \"134c704f-9b21-4f2e-91b3-4a467353bcc0\", \"shortName\": \"CISA-ADP\", \"dateUpdated\": \"2024-10-24T14:25:27.893Z\"}}]}",
