{"id":"CVE-2021-21277","state":"PUBLISHED","title":"Angular Expressions - Remote Code Execution","description":"angular-expressions is \"angular's nicest part extracted as a standalone module for the browser and node\". In angular-expressions before version 1.1.2 there is a vulnerability which allows Remote Code Execution if you call \"expressions.compile(userControlledInput)\" where \"userControlledInput\" is text that comes from user input. The security of the package could be bypassed by using a more complex payload, using a \".constructor.constructor\" technique. In terms of impact: If running angular-expressions in the browser, an attacker could run any browser script when the application code calls expressions.compile(userControlledInput). If running angular-expressions on the server, an attacker could run any Javascript expression, thus gaining Remote Code Execution. This is fixed in version 1.1.2 of angular-expressions A temporary workaround might be either to disable user-controlled input that will be fed into angular-expressions in your application or allow only following characters in the userControlledInput.","publishedAt":"2021-02-01T15:05:24.000Z","updatedAt":"2024-08-03T18:09:15.102Z","severity":{"score":8.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["peerigon angular-expressions"],"affected":[{"vendor":"peerigon","product":"angular-expressions","versions":[{"version":"< 1.1.2","status":"affected"}]}],"references":["https://github.com/peerigon/angular-expressions/security/advisories/GHSA-j6px-jwvv-vpwq","https://www.npmjs.com/package/angular-expressions","http://blog.angularjs.org/2016/09/angular-16-expression-sandbox-removal.html","https://github.com/peerigon/angular-expressions/commit/07edb62902b1f6127b3dcc013da61c6316dd0bf1"],"weaknesses":["CWE-74"],"ingestedAt":"2026-10-29T19:47:59.168Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2021/21xxx/CVE-2021-21277.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2021-21277","state":"PUBLISHED","datePublished":"2021-02-01T15:05:24.000Z","dateUpdated":"2024-08-03T18:09:15.102Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2020-12-22T00:00:00.000Z"},"containers":{"cna":{"title":"Angular Expressions - Remote Code Execution","descriptions":[{"lang":"en","value":"angular-expressions is \"angular's nicest part extracted as a standalone module for the browser and node\".
