Improper Certificate Validation

Coder is vulnerable to Improper Certificate Validation. The vulnerability is due to the AI Bridge Proxy aibridgeproxyd creating a default HTTPS transport with InsecureSkipVerify enabled when no upstream proxy is configured, which allows an on-path man-in-the-middle attacker to present a forged TL...

Coder 2.30.x < 2.32.7 / 2.33.x < 2.33.8 / 2.34.x < 2.34.2 AI Bridge Proxy TLS Verification Bypass

The version of Coder installed on the remote host is 2.30.x prior to 2.32.7, 2.33.x prior to 2.33.8, or 2.34.x prior to 2.34.2. It is, therefore, affected by a vulnerability. The AI Bridge Proxy skips TLS certificate verification in the default configuration. The proxy created a goproxy server...

CVE-2026-55436

Coder allows organizations to provision remote development environments via Terraform. Starting in version 2.30.0 and prior to versions 2.32.7, 2.33.8, and 2.34.2, the AI Bridge Proxy aibridgeproxyd created a goproxy server whose default transport set InsecureSkipVerify: true and only assigned a...

CVE-2026-55436

The CVE-2026-55436 issue affects Coder’s AI Bridge Proxy (aibridgeproxyd) in versions prior to 2.32.7, 2.33.8, and 2.34.2. The root cause is that the proxy’s default goproxy transport uses InsecureSkipVerify: true and only switches to a secure transport if an upstream proxy is configured; thus ou...

CVE-2026-55435

Coder allows organizations to provision remote development environments via Terraform. Starting in version 2.30.0 and prior to versions 2.32.7, 2.33.8, and 2.34.2, AI Bridge proxy endpoints authenticate via Server.IsAuthorized in coderd/aibridgedserver, which validates key format, expiry, secret...

GHSA-84RM-42XW-MX52 Coder's AI Bridge Proxy skips TLS certificate verification in default configuration

Summary The AI Bridge Proxy aibridgeproxyd created a goproxy server whose default transport set InsecureSkipVerify: true and only assigned a secure transport when an upstream proxy was configured. In the default configuration no upstream proxy, outbound HTTPS to the Coder access URL accepted any...

Suspended Coder users retain access to AI Bridge LLM proxy endpoints

Summary AI Bridge proxy endpoints authenticate via Server.IsAuthorized in coderd/aibridgedserver, which validates key format, expiry, secret and deleted or system users but does not check whether the account is suspended. Because suspension does not revoke existing API keys, a suspended user's...

CVE-2026-47209 vm2: Bridge Proxy set trap ignores receiver parameter, enabling host object property injection via prototype chain

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, the BaseHandler.set trap in bridge.js line 1231 ignores the receiver parameter and unconditionally writes to the host target object. Per the Proxy set trap specification, when receiver !== proxy e.g., when a child object...

CVE-2026-47209

vm2 (Node.js sandbox) had a vulnerability in the BaseHandler.set trap that ignores the receiver parameter and always writes to the host target, enabling inherited-property writes to leak onto host objects via prototype chains. This can allow attackers to assign Symbol-keyed properties (e.g., node...

vm2's Bridge Proxy set trap ignores receiver parameter, enabling host object property injection via prototype chain

Summary The BaseHandler.set trap in bridge.js line 1231 ignores the receiver parameter and unconditionally writes to the host target object. Per the Proxy set trap specification, when receiver !== proxy e.g., when a child object inherits from the proxy via Object.create, the property assignment...

Arbitrary Code Injection

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Arbitrary Code Injection through the BaseHandler write traps in lib/bridge.js. An attacker can mutate host Object.prototype, Array.prototype,...

GHSA-VWRP-X96C-MHWQ vm2: Mutable Proxies for Host Intrinsic Prototypes Allows Sandbox Escape

Summary vm2's bridge exposes mutable proxies for real host-realm intrinsic prototypes and then forwards sandbox writes into the underlying host objects with otherReflectSet and otherReflectDefineProperty, which lets attacker-controlled JavaScript running in a default VM or inherited NodeVM mutate...
