# CVE-2026-52855: Wings exposes node configuration secrets through egg configuration-file templating

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (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 0.5% , percentile 42: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 42% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes github.com/pterodactyl/wings (Go) < 1.12.3, fixed in 1.12.3 . Check your lockfile, including transitive dependencies.

## What it is

Wings is the server control plane for Pterodactyl, a free, open-source game server management panel. Prior to 1.12.3, {{config.}} placeholders in egg configuration-file templates allow a low-privileged user to read {{config.token}}, {{config.tokenid}}, and {{config.docker.registries}} from the full daemon configuration. This issue is fixed in version 1.12.3.

## Affected packages

- Go `github.com/pterodactyl/wings` < 1.12.3 → fixed: 1.12.3

## Affected products (CVE record)

- pterodactyl wings: < 1.12.3

## Severity

- GitHub_M CVSS 3.1: 9.9 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.9 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/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): 0.51% probability of exploitation activity in the next 30 days; percentile 42.
