Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-33144 is a spoofing vulnerability affecting Visual Studio Code, assigned CWE-23 for relative path traversal. It carries a CVSS 3.1 base score of 6.6 reflecting local attack vector, low attack complexity, low privileges required, and required user interaction, resulting in high impact to confidentiality and integrity with no availability effect.

An attacker with local access and limited privileges can exploit the flaw by presenting a crafted resource that the victim is tricked into opening or interacting with inside Visual Studio Code, enabling unauthorized disclosure or modification of files on the system.

Microsoft has published guidance for the issue in its Security Response Center advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2023-33144.

The EPSS score for this CVE rose materially from a low baseline to a peak of 0.0762 on 2025-01-22 before receding to its current value of 0.0072, indicating a period of increased exploitation interest after disclosure.

prevents

Secure SDLC practices directly require input validation and path sanitization that prevent relative traversal.

finds

Security testing in development catches path traversal via static/dynamic analysis, but does not itself implement the fix.

prevents

Secure development lifecycle mandates input validation and path-handling controls that directly prevent relative path traversal.

prevents

Application security requirements explicitly call for controls against path traversal and other injection flaws.

prevents

Secure architecture principles include directory isolation and canonicalization, reducing but not eliminating traversal risk.

prevents

Secure coding standards require neutralizing path traversal sequences, directly addressing CWE-23.

mitigates

Information access restriction limits which files can be reached, mitigating impact but not preventing the traversal flaw.
