CVE-2024-4099

Status: AnalyzedMedium (5.3)—

An issue has been discovered in GitLab EE affecting all versions starting from 16.0 prior to 17.2.8, from 17.3 prior to 17.3.4, and from 17.4 prior to 17.4.1. An AI feature was found to read unsanitized content in a way that could have allowed an attacker to hide prompt injection.

CVSS

Exploitation probability (EPSS)

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).
