Publication date: 2026-03-23

Last updated on: 2026-04-29

Assigner: VulDB

Description
A vulnerability was determined in kalcaddle kodbox 1.64. Impacted is the function shareSafeGroup of the file /workspace/source-code/app/controller/explorer/shareOut.class.php of the component Site-level API key Handler. This manipulation of the argument sk causes use of hard-coded cryptographic key . The attack may be initiated remotely. The complexity of an attack is rather high. The exploitability is considered difficult. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.

Impact Analysis

The vulnerability allows an attacker to manipulate the argument 'sk' to cause the system to use a hard-coded cryptographic key. This can potentially compromise the security of the Site-level API key Handler, leading to partial confidentiality loss (as indicated by the CVSS impact on confidentiality). However, the attack complexity is high and exploitability is difficult, which may limit the likelihood of successful exploitation.
