CVE-2026-57926: CWE-1321 in JetBrains YouTrack
In JetBrains YouTrack before 2026.2.16593 the websandbox bridge was vulnerable to a prototype pollution attack
AI Analysis
Technical Summary
CVE-2026-57926 is a prototype pollution vulnerability affecting the websandbox bridge component of JetBrains YouTrack prior to version 2026.2.16593. Prototype pollution can lead to unexpected behavior by modifying the prototype of base objects, but in this case, the impact is limited as reflected by the low CVSS score (2.6). The vulnerability requires network attack vector with high attack complexity, low privileges, and user interaction. Confidentiality is not impacted, integrity impact is low, and availability is unaffected. No official remediation level or patch information is currently available.
Potential Impact
The vulnerability allows prototype pollution which may cause limited integrity issues in the affected YouTrack component. There is no impact on confidentiality or availability. The low CVSS score and absence of known exploits suggest limited practical risk at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or workaround is currently documented, users should monitor JetBrains advisories for updates and consider minimizing exposure of the websandbox bridge component until a fix is released.
