SUSE CVE-2026-55427

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, coder config-ssh wrote server-supplied SSH settings HostnameSuffix, SSHConfigOptions into the user's /.ssh/config without sanitizing embedded newlines or...

Coder < 2.29.17 / 2.30.x < 2.32.7 / 2.33.x < 2.33.8 / 2.34.x < 2.34.2 Multiple Vulnerabilities

The version of Coder installed on the remote host is prior to 2.29.17, 2.32.7, 2.33.8, or 2.34.2. It is, therefore, affected by multiple vulnerabilities: - A user-admin role can reset the owner account password, resulting in privilege escalation from user-admin to owner. CVE-2026-55077 - A...

CVE-2026-55427 Coder vulnerable to SSH config injection via unsanitized server-supplied values in `coder config-ssh`

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, coder config-ssh wrote server-supplied SSH settings HostnameSuffix, SSHConfigOptions into the user's /.ssh/config without sanitizing embedded newlines or...

CVE-2026-55427

Coder exposes SSH config injection risk via the config-ssh command: before 2.34.2, 2.33.8, 2.32.7, and 2.29.17, server-supplied values for HostnameSuffix and SSHConfigOptions could be written into ~/.ssh/config without rejecting newlines or restricting directives. This could enable a malicious or...

curl: ssh_config_matches is dead code: unauthorized SSH key reuse

Summary libcurl's SSH connection-reuse guard sshconfigmatches — added for CVE-2022-27782 and reaffirmed by CVE-2023-27538 — is dead code in every release since 7.83.1. It compares sshc-rsa / sshc-rsapub between a new transfer "needle" and a pooled connection, but on both sides those pointers are...

curl: SSH/SFTP connection reuse can bypass SSH key identity after ssh_config_matches removal

Summary: libcurl's SSH/SFTP connection reuse logic no longer binds a pooled SSH connection to the SSH key identity requested by the new transfer. After sshconfigmatches was removed, urlmatchprotoconfig again has no SSH-specific check for CURLOPTSSHPUBLICKEYFILE or CURLOPTSSHPRIVATEKEYFILE. An...
