CVE-2026-11622 Potential memory usage beyond configured limits

A DNSSEC validating resolver that is under a random subdomain attack against a DNSSEC-signed zone can suffer from runaway memory usage. The attacker needs to be able to send queries faster than the resolver can perform validation. The increased memory usage can be orders of magnitude beyond the...

CVE-2026-41839

A flaw was found in Spring Framework. A remote attacker, by compromising a subdomain of a WebFlux application for example, through cross-site scripting XSS, could exploit this vulnerability to escalate privileges. This allows the attacker to exchange a known session ID for that of an authenticate...

Security Advisory Description A WebFlux application with a compromised subdomain for example, compromised via cross-site scripting XSS is vulnerable to an escalation attack exchanging a known session ID for that of an authenticated user. Affected versions: Spring Framework 7.0.0 through 7.0.7;...

CVE-2026-55438

Coder allows organizations to provision remote development environments via Terraform. Prior to versions 2.29.17, 2.32.7, 2.33.8, and 2.34.2, Coder's subdomain-based workspace app proxy allowed the same-owner CORS check to be bypassed. When a workspace-name subdomain segment parsed as a UUID, the...

CVE-2026-55430

Coder allows organizations to provision remote development environments via Terraform. Prior to versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2, the workspace app proxy resolves the target app from httpapi.RequestHost which prefers the X-Forwarded-Host header over the real Host header. No middleware...

CVE-2026-55438

Coder's workspace app CORS origin check can be bypassed via UUID-based subdomain spoofing. Prior to versions 2.29.17, 2.32.7, 2.33.8, and 2.34.2, subdomain-based proxy would bypass the same-owner CORS check when a workspace-name segment parsed as a UUID. The workspace could be resolved by ID with...

CVE-2026-55432 Coder's sub-agent app registration bypasses template port-sharing policy enforcement

Coder allows organizations to provision remote development environments via Terraform. Prior to versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2, the CreateSubAgent RPC did not validate a requested app sharing level against the template's MaxPortSharingLevel before persisting workspace apps, letting a...

CVE-2026-55430

Coder's workspace app (github.com/coder/coder) prior to versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2 trusts X-Forwarded-Host for routing because no middleware strips it before routing and httpapi.RequestHost() prefers that header over Host. This enables cross-app data access when subdomain (wildca...
