Official Description
JD-GUI 1.6.6 allows deserialization via UIMainWindowPreferencesProvider.singleInstance.
Risk Analysis
JD-GUI 1.6.6 is vulnerable to insecure deserialization, which can allow an attacker to execute arbitrary code. Given the critical CVSS score of 9.8, this flaw represents a significant risk as it is remotely exploitable without authentication.
There is no known public exploit for this vulnerability, and it is not listed in the CISA KEV catalog.
Users should upgrade to a version of JD-GUI that addresses this deserialization vulnerability.
Technical Analysis
CVE-2023-26234 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
