Description
openapi-typescript-codegen through 0.31.0 contains a code injection vulnerability that allows attackers controlling an OpenAPI document to inject JavaScript by supplying unescaped values interpolated into single-quoted string literals. Attackers can embed a single quote in path keys, parameter names, servers[0].url, or info.version to execute arbitrary JavaScript when generated clients are imported or service methods called.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
No fixed release is recorded for CVE-2026-108551 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
