CVE-2026-4623: A security vulnerability has been detected in DefaultFuction Jeson-Customer-Relationship-Management-System up to 1b4679c4d06b90d31dd521c2b000bfdec5a36e00. This affects an unknown function of the file /api/System.php of the component API Module. The manipulation of the argument url leads to server-side request forgery. The attack can be initiated remotely. The exploit has been disclosed publicly and may be used. Continious delivery with rolling releases is used by this product. Therefore, no version details of affected nor updated releases are available. The identifier of the patch is f76e7123fe093b8675f88ec8f71725b0dd186310/98bd4eb07fa19d4f2c5228de6395580013c97476. It is suggested to install a patch to address this issue.
The exploitability of CVE-2026-4623 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
With low attack complexity and no required privileges, CVE-2026-4623 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2026-4623, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2026-4623, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
