Description
A vulnerability was found in Studio-Saelix Sencho up to 0.94.1. This affects an unknown part of the file /api/auth/login of the component Login Endpoint. Performing a manipulation of the argument X-Forwarded-For results in improper authentication. The attack is possible to be carried out remotely. The exploit has been made public and could be used. The patch is named 79b86ddcd4aefdd6941f098e35990ab397b13c72. To fix this issue, it is recommended to deploy a patch. The vendor confirms: "The login limiter relied on client-supplied X-Forwarded-For data without an explicit trusted-proxy boundary, allowing an attacker to rotate the apparent client address. The remediation now ignores forwarding headers by default, accepts them only from explicitly configured proxy CIDRs, and adds a separate failed-attempt limit keyed by normalized account identity."
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-2026-108522 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
