Description

Summary

Workspace Agent manifests containing sensitive values were logged in plaintext unsanitized

Details

By default Workspace Agent logs are redirected to stderr https://github.com/coder/coder/blob/a8862be546f347c59201e2219d917e28121c0edb/cli/agent.go#L432-L439

Workspace Agent Manifests containing sensitive environment variables were logged insecurely https://github.com/coder/coder/blob/7beb95fd56d2f790502e236b64906f8eefb969bd/agent/agent.go#L1090

An attacker with limited local access to the Coder Workspace (VM, K8s Pod etc.) or a third-party system (SIEM, logging stack) could access those logs

This behavior opened room for unauthorized access and privilege escalation

Impact

Impact varies depending on the environment variables set in a given workspace

Patches

Fix was released & backported:

Workarounds

One potential workaround is to disable Workspace Agent Logs by setting following configuration option CODER_AGENT_LOGGING_HUMAN=/dev/null

platform operators are advised to upgrade their deployments

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/coder/coder/v2. 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.

  2. Fix

    Update github.com/coder/coder/v2 to 2.26.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jf75-p25m-pw74 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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-jf75-p25m-pw74 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 GHSA-jf75-p25m-pw74. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
