# CVE-2026-25505: Bambuddy Uses Hardcoded Secret Key + Many API Endpoints do not Require Authentication

**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?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- 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 bambuddy (PyPI) < 0.1.7, fixed in 0.1.7 . Check your lockfile, including transitive dependencies.

## What it is

Bambuddy is a self-hosted print archive and management system for Bambu Lab 3D printers. Prior to version 0.1.7, a hardcoded secret key used for signing JWTs is checked into source code and ManyAPI routes do not check authentication. This issue has been patched in version 0.1.7.

## Affected packages

- PyPI `bambuddy` < 0.1.7 → fixed: 0.1.7
