CVE-2024-54152Public exploitNetwork attack vector

Arbitrary code execution via inherited locals properties

Published Dec 10, 2024 · Updated Dec 10, 2024

Code injection in Peerigon angular-expressions before 1.4.3 allows remote attackers to execute arbitrary code via crafted expressions. When compile() receives both scope and locals, ASTCompiler resolves inherited locals properties without an own-property check, so proto.constructor exposes the Function constructor. Exploitation requires an application to evaluate attacker-controlled expressions with a nonempty locals argument; successful payloads run with the host process's privileges.
