# CVE-2024-54152: Angular Expressions - Remote Code Execution when using locals

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 2.2% , percentile 83: FIRST’s model estimates a 2.2% chance of exploitation activity in the next 30 days, higher than 83% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes angular-expressions (npm) < 1.4.3, fixed in 1.4.3 . Check your lockfile, including transitive dependencies.

## What it is

Angular Expressions provides expressions for the Angular.JS web framework as a standalone module. Prior to version 1.4.3, an attacker can write a malicious expression that escapes the sandbox to execute arbitrary code on the system. With a more complex (undisclosed) payload, one can get full access to Arbitrary code execution on the system. The problem has been patched in version 1.4.3 of Angular Expressions. Two possible workarounds are available. One may either disable access to proto globally or make sure that one uses the function with just one argument.

## Affected packages

- npm `angular-expressions` < 1.4.3 → fixed: 1.4.3

## Affected products (CVE record)

- peerigon angular-expressions: < 1.4.3

## Severity

- GitHub_M CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N`
- GitHub CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 2.24% probability of exploitation activity in the next 30 days; percentile 83.
