CVE-2026-48923: Vulnerability in Jenkins Project Jenkins AppSpider Plugin
Jenkins AppSpider Plugin 1.0.17 and earlier does not perform a permission check in a method implementing form validation, allowing attackers with Overall/Read permission to connect to an attacker-specified URL.
AI Analysis
Technical Summary
The Jenkins AppSpider Plugin up to version 1.0.17 does not enforce permission checks in a form validation method, enabling users with Overall/Read permission to initiate connections to attacker-controlled URLs. This could potentially be leveraged to cause unintended network interactions or information disclosure depending on the context of the URL connection. The vulnerability is documented as CVE-2026-48923 but lacks a CVSS score and vendor-provided remediation details at this time.
Potential Impact
Users with Overall/Read permission on Jenkins can exploit this vulnerability to make the Jenkins server connect to arbitrary URLs. This could lead to information disclosure or facilitate other attacks depending on the external URL's nature. There are no known exploits in the wild and no official patch or fix has been confirmed yet.
Mitigation Recommendations
Patch status is not yet confirmed — check the Jenkins Project advisory for current remediation guidance. Until an official fix is released, restrict Overall/Read permissions to trusted users only to reduce risk.
