# CVE-2023-7272: Eclipse Parsson stack overflow when parsing deeply nested input

**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 0.6% , percentile 47: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 47% of all scored CVEs (low). 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 org.eclipse.parsson:parsson (Maven) >= 1.1.0, < 1.1.3, fixed in 1.1.3 ; org.eclipse.parsson:parsson (Maven) < 1.0.4, fixed in 1.0.4 . Check your lockfile, including transitive dependencies.

## What it is

In Eclipse Parsson before 1.0.4 and 1.1.3, a document with a large depth of nested objects can allow an attacker to cause a Java stack overflow exception and denial of service. Eclipse Parsson allows processing (e.g. parse, generate, transform and query) JSON documents.

## Affected packages

- Maven `org.eclipse.parsson:parsson` >= 1.1.0, < 1.1.3 → fixed: 1.1.3
- Maven `org.eclipse.parsson:parsson` < 1.0.4 → fixed: 1.0.4

## Affected products (CVE record)

- Eclipse Foundation Parsson: <= 1.0.3, 1.1.0 <= 1.1.2

## Severity

- eclipse CVSS 3.1: 8.6 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H`
- GitHub CVSS 4.0: 9.2 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact partial .
- FIRST EPSS (model of 2026-10-21): 0.59% probability of exploitation activity in the next 30 days; percentile 47.
