SCA: security update for @saltcorn/server (GHSA-f3g8-9xv5-77gv)

medium Tenable Self-Hosted Container Security Plugin ID 441134

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Saltcorn is an extensible, open source, no-code database application builder. Prior to versions 1.4.6,
1.5.6, and 1.6.0-beta.5, Saltcorn validates the post-login dest parameter with a string check that only
blocks :/ and //. Because all WHATWG-compliant browsers normalise backslashes (\) to forward slashes (/)
for special schemes, a payload such as /\evil.com/path slips through is_relative_url(), is emitted
unchanged in the HTTP Location header, and causes the browser to navigate cross-origin to an attacker-
controlled domain. The bug is reachable on a default install and only requires a victim who can be tricked
into logging in via a crafted Saltcorn URL. This issue has been patched in versions 1.4.6, 1.5.6, and
1.6.0-beta.5. (CVE-2026-42259)

Solution

Update the @saltcorn/server library and its related packages to version 1.4.6 or later.
