CVE-2026-44643

## Impact An attacker can write a malicious expression that escapes the sandbox to execute arbitrary code on the system. Example of vulnerable code: ``` const expressions = require("angular-expressions"); const result = expressions.compile("a | __proto__")({}, {}); ``` This should throw the error : Filter '__proto__' is not defined, however, this shows : Uncaught SyntaxError: Unexpected identifier 'Object' With a more complex (undisclosed) payload, one can get full access to Arbitrary code execution on the system. ## Vulnerable versions : angular-expressions <= 1.5.1 ## Patches The problem has been patched in version 1.5.2 of angular-expressions. ## Credits Credits go to San Gil from [www.securityoffice.io](https://securityoffice.io/) who has found the issue and reported it to us.
