CVE-2025-66411 | Coder logged sensitive objects unsanitized

Exp

Coder allows organizations to provision remote development environments via Terraform. Prior to 2.26.5, 2.27.7, and 2.28.4, Workspace Agent manifests containing sensitive values were logged in plaintext unsanitized. 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 vulnerability is fixed in 2.26.5, 2.27.7, and 2.28.4.

CVSS metrics for this CVE.

Base score Version Severity Vector Exploitability Impact Score source
7.8 3.1 HIGH
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
