Severity by source
AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Local delivery via crafted workspace (AV:L), no special privileges needed (PR:N), but user must open the malicious content (UI:R); all three CIA pillars high because VSCode process runs as the developer user with full filesystem access.

Incomplete list of disallowed inputs in Visual Studio Code allows an unauthorized attacker to bypass a security feature locally.
AnalysisAI
Security feature bypass in Visual Studio Code before 1.136.2 allows a local attacker to circumvent an input-validation blocklist (CWE-184), resulting in high confidentiality, integrity, and availability impact. The vulnerability requires user interaction - most plausibly opening a crafted workspace or file - but no elevated privileges. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target user to open a malicious workspace, project folder, or file in an affected version of Visual Studio Code (< 1.136.2) - reflecting the CVSS UI:R requirement. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 7.8 with a local vector (AV:L/AC:L/PR:N/UI:R) reflects moderate real-world reach: exploitation is bounded by local file-system access or, more practically, the social engineering step of convincing a developer to open a crafted project. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update Visual Studio Code to version 1.136.2 or later, which is the vendor-confirmed patched release per the MSRC advisory (https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-70334). … Detailed patch versions, workarounds, and compensating controls in full report. |
