{"id":"CVE-2022-23543","state":"PUBLISHED","title":"HTML attributes when attaching a YouTube link to the post","description":"Silverware Games is a social network where people can play games online. Users can attach URLs to YouTube videos, the site will generate related `<iframe>` when the post will be published. The handler has some sort of protection so non-YouTube links can't be posted, as well as HTML tags are being stripped. However, it was still possible to add custom HTML attributes (e.g. `onclick=alert(\"xss\")`) to the `<iframe>'. This issue was fixed in the version `1.1.34` and does not require any extra actions from our members. There has been no evidence that this vulnerability was used by anyone at this time.","publishedAt":"2022-12-19T21:30:09.836Z","updatedAt":"2025-04-15T19:01:44.429Z","severity":{"score":6.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["mesosoi silverwaregames-io-issue-tracker"],"affected":[{"vendor":"mesosoi","product":"silverwaregames-io-issue-tracker","versions":[{"version":"< 1.1.34","status":"affected"}]}],"references":["https://github.com/mesosoi/silverwaregames-io-issue-tracker/security/advisories/GHSA-62r9-4v3r-rw89"],"weaknesses":["CWE-80"],"ingestedAt":"2026-10-29T19:49:40.939Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2022/23xxx/CVE-2022-23543.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2022-23543","state":"PUBLISHED","datePublished":"2022-12-19T21:30:09.836Z","dateUpdated":"2025-04-15T19:01:44.429Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2022-01-19T21:23:53.796Z"},"containers":{"cna":{"title":"HTML attributes when attaching a YouTube link to the post","descriptions":[{"lang":"en","value":"Silverware Games is a social network where people can play games online.
