# CVE-2024-22533: Beetl Server-Side Template Injection vulnerability

**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 1.0% , percentile 63: FIRST’s model estimates a 1.0% chance of exploitation activity in the next 30 days, higher than 63% 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 com.ibeetl:beetl-core (Maven) < 3.15.13.RELEASE, fixed in 3.15.13.RELEASE . Check your lockfile, including transitive dependencies.

## What it is

Before Beetl v3.15.12, the rendering template has a server-side template injection (SSTI) vulnerability. When the incoming template is controllable, it will be filtered by the DefaultNativeSecurityManager blacklist. Because blacklist filtering is not strict, the blacklist can be bypassed, leading to arbitrary code execution.

## Affected packages

- Maven `com.ibeetl:beetl-core` < 3.15.13.RELEASE → fixed: 3.15.13.RELEASE

## Affected products (CVE record)

- n/a n/a: see advisory

## Severity

- CISA-ADP CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## 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): 1.03% probability of exploitation activity in the next 30 days; percentile 63.
