Description

SpiceDB is an open source, Google Zanzibar-inspired database for creating and managing security-critical application permissions. When the provided datastore URI is malformed (e.g. by having a password which contains :) the full URI (including the provided password) is printed, so that the password is shown in the logs. Version 1.27.0-rc1 patches this issue.

Example output:

terminated with errors error="unable to create migration driver for postgres: parse \"postgres://spicedb:<PASSWORD IN PLAINTEXT>": invalid port \"<PASSWORD IN PLAINTEXT>\" after host"

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/authzed/spicedb, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/authzed/spicedb to 1.27.0-rc1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-46255 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
