Directory traversal vulnerability in ArsDigita Community System (ACS) 3.4.10 and earlier, and ArsDigita Community Education Solution (ACES) 1.1, allows remote attackers to read arbitrary files via .%252e/ (double-encoded dot dot slash) sequences in the URI.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:C/I:N/A:N
Base score: 7.8

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 2.97%
Percentile among all scored CVEs: 87
Score date: 10/7/2026

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).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
