# CVE-2026-44643: Angular Expressions - Remote Code Execution using filters

**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 0.7% , percentile 52: FIRST’s model estimates a 0.7% chance of exploitation activity in the next 30 days, higher than 52% of all scored CVEs (moderate). 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) <= 1.5.1, fixed in 1.5.2 . 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 1.5.2, an attacker can write a malicious expression using filters that escapes the sandbox to execute arbitrary code on the system. This vulnerability is fixed in 1.5.2.

## Affected packages

- npm `angular-expressions` <= 1.5.1 → fixed: 1.5.2

## Affected products (CVE record)

- peerigon angular-expressions: < 1.5.2

## 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 yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.69% probability of exploitation activity in the next 30 days; percentile 52.
