In versions on the 4.x branch prior to versions 4.0.10, 4.2.8, and 4.2.0-rc2, under certain conditions, attackers can abuse the translation feature to bypass the server-side HTML sanitization, allowing unescaped HTML to execute in the browser. The impact is limited thanks to Mastodon's strict Content Security Policy, blocking inline scripts, etc. However a CSP bypass or loophole could be exploited to execute malicious XSS. Furthermore, it requires user interaction, as this can only occur upon clicking the “Translate” button on a malicious post. Versions 4.0.10, 4.2.8, and 4.2.0-rc2 contain a patch for this issue."}],"source":{"advisory":"GHSA-2693-xr3m-jhqr","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T19:23:38.536Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/mastodon/mastodon/security/advisories/GHSA-2693-xr3m-jhqr","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/mastodon/mastodon/security/advisories/GHSA-2693-xr3m-jhqr"},{"name":"https://github.com/mastodon/mastodon/commit/ff32475f5f4a84ebf9619e7eef5bf8b4c075d0e2","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/mastodon/mastodon/commit/ff32475f5f4a84ebf9619e7eef5bf8b4c075d0e2"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-09-24T18:00:36.912577Z","id":"CVE-2023-42452","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-24T18:11:03.787Z"}}]}}
