SCA: security update for github.com/dadrus/heimdall (GHSA-43jv-5j4x-qv67)
high Tenable Self-Hosted Container Security Plugin ID 440888
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Heimdall is a cloud native Identity Aware Proxy and Access Control Decision service. Prior to version
0.17.14, Heimdall handles URL-encoded slashes (%2F) in a case-sensitive manner, while percent-encoding is
defined to be case-insensitive. As a result, the lowercase equivalent (%2f) is not recognized and
therefore not processed as expected when allow_encoded_slashes is set to off (the default setting). This
discrepancy can lead to differences in how request paths are interpreted by heimdall and upstream
components, which may result in authorization bypass. This issue has been patched in version 0.17.14.
(CVE-2026-42272)
Solution
Update the github.com/dadrus/heimdall library and its related packages to version 0.17.14 or later.See Also
