Improper escaping of encrypted topic titles could lead to a cross site scripting (XSS) issue when a site has content security policy (CSP) headers disabled. Having CSP disabled is a non-default configuration, and having it disabled with discourse-encrypt installed will result in a warning in the Discourse admin dashboard. This has been fixed in commit `9c75810af9` which is included in the latest version of the discourse-encrypt plugin. Users are advised to upgrade. Users unable to upgrade should ensure that CSP headers are enabled and properly configured."}],"source":{"advisory":"GHSA-5fh6-wp7p-xx7v","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T19:44:44.057Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/discourse/discourse-encrypt/security/advisories/GHSA-5fh6-wp7p-xx7v","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/discourse/discourse-encrypt/security/advisories/GHSA-5fh6-wp7p-xx7v"},{"name":"https://github.com/discourse/discourse-encrypt/commit/9c75810af9a474d7edaec67dea66f852c0ba1f4e","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/discourse/discourse-encrypt/commit/9c75810af9a474d7edaec67dea66f852c0ba1f4e"},{"name":"https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP","tags":["x_refsource_MISC","x_transferred"],"url":"https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP"}]},{"affected":[{"vendor":"discourse","product":"discourse-encrypt","cpes":["cpe:2.3:a:discourse:discourse-encrypt:-:*:*:*:*:discourse:*:*"],"defaultStatus":"unknown","versions":[{"version":"0","status":"affected","lessThanOrEqual":"c492904c","versionType":"git"}]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-09-23T18:19:59.485389Z","id":"CVE-2023-43657","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-23T18:21:57.902Z"}}]}}
