Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target be running IntelliJ IDEA before 2026.2 with the Remote Development feature active and an accessible Remote Development session - this is the specific deployment mode named in the CVE. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are mixed. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who can reach or interpose on an IntelliJ IDEA Remote Development session sends configuration changes the backend should have rejected, altering IDE settings such as tool paths or run/build configuration to achieve unauthorized control over the remote host environment. Given the CVSS AV:N/AC:L/PR:N profile, this would require no authentication and low complexity, though the sparse description leaves the exact triggering mechanism unconfirmed. … |
| Remediation | Vendor-released patch: IntelliJ IDEA 2026.2 - upgrade all IntelliJ IDEA instances used for Remote Development to 2026.2 or later, per the JetBrains fixed-issues page at https://www.jetbrains.com/privacy-security/issues-fixed/. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
