CVE-2025-61593

Status: AnalyzedHigh (8.8)—

Cursor is a code editor built for programming with AI. In versions 1.7 and below, a vulnerability in the way Cursor CLI Agent protects its sensitive files (i.e. */.cursor/cli.json) allows attackers to modify the content of the files through prompt injection, thus achieving remote code execution. A prompt injection can lead to full RCE through modifying sensitive files on case-insensitive filesystems. This issue is fixed in a commit, 25b418f, but has yet to be released as of October 3, 2025.

CVSS

Version: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Base score: 8.8

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.41%
Percentile among all scored CVEs: 33
Score date: 10/5/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
