Description
Scriban before 7.5.2 contains an information disclosure and object manipulation vulnerability that allows template authors to access .NET internals of function values through reflection member accessors. Attackers can use array.map to read Target, Method, or ReturnType on imported delegates, exposing and overwriting service properties, captured closure secrets, and assembly paths.
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
The records we use list no fixed release for CVE-2026-124438. Check the upstream advisory for a patched version, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
