CVE-2023-46255 is a medium-severity (CVSS 4.2) CWE-532 vulnerability in github.com/authzed/spicedb. O3 Security confirms whether CVE-2023-46255 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
`SPICEDB_DATASTORE_CONN_URI` is leaked when URI cannot be parsed
Real-World Exposure

Description
SpiceDB is an open source, Google Zanzibar-inspired database for creating and managing security-critical application permissions. Prior to version 1.27.0-rc1, 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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/authzed/spicedb. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
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.
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.
How O3 protects you
O3 pinpoints whether CVE-2023-46255 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2023-46255. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
