Routine

MEDIUM 6.1DOWNGRADEDOWNGRADEDOWNGRADE

CVE-2026-0505 is a medium-severity flaw (CVSS 6.1) affecting document management system, erp, s4core. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The BSP applications allow an unauthenticated user to manipulate user-controlled URL parameters that are not sufficiently validated. This could result in unvalidated redirection to attacker-controlled websites, leading to a low impact on confidentiality and integrity, and no impact on the availability of the application.

Why this priority
